Unprecedented community containment measures were taken following the recent outbreak of COVID-19 in Italy. The aim of the study was to explore the self-reported future compliance of citizens with such measures and its relationship with potentially impactful psychological variables.. An online survey was completed by 931 people (18-76 years) distributed across the Italian territory. In addition to demographics, five dimensions were measured: self-reported compliance with containment measures over time (today, at 7, 14, 30, 60, 90, and 180 days from now) at three hypothetical risk levels (10, 50, 90% of likelihood of contracting the COVID-19), perceived risk, generalized anxiety, intolerance of uncertainty, and relevance of several psychological needs whose satisfaction is currently precluded.. The duration of containment measures plays a crucial role in tackling the spread of the disease as people will be less compliant over time. Psychological needs of citizens impacting on the compliance should be taken into account when planning an easing of the lockdown, along with interventions for protecting vulnerable groups from mental distress.. La apendicitis aguda (AA) es la urgencia quirúrgica abdominal más frecuente. No encontramos estudios específicos que evalúen el impacto de la pandemia causada por el coronavirus 2 (SARS-Cov-2) sobre la AA y su tratamiento quirúrgico. Analizamos la influencia de esta nueva patología sobre la AA.. Estudio observacional retrospectivo en pacientes intervenidos por AA desde enero hasta abril de 2020. Fueron clasificados según el momento de la apendicectomía, antes de la declaración del estado de alarma (Pre-COVID19) y después de la declaración del estado de alarma (Post-COVID19) en España. Se evaluaron variables demográficas, duración de la sintomatología, tipo de apendicitis, tiempo quirúrgico, estancia hospitalaria y complicaciones postoperatorias.. La pandemia por SARS-Cov-2 influye en el momento de diagnóstico de la apendicitis, así como en su grado de evolución y estancia hospitalaria. La peritonitis fue lo más frecuentemente observado. Una sospecha y orientación clínica más temprana, es necesaria para evitar un manejo inadecuado de este trastorno quirúrgico común.. The primary outcome is improvement in PaO. Findings will provide timely information on the safety, efficacy, and optimal dosing of t-PA to treat moderate/severe COVID-19-induced ARDS, which can be rapidly adapted to a phase III trial (NCT04357730; FDA IND 149634).. None.. The gut barrier is crucial in cirrhosis in preventing infection-causing bacteria that normally live in the gut from accessing the liver and other organs via the bloodstream. Herein, we characterised gut inflammation by measuring different markers in stool samples from patients at different stages of cirrhosis and comparing this to healthy people. These markers, when compared with equivalent markers usually measured in blood, were found to be very different in pattern and absolute levels, suggesting that there is significant gut inflammation in cirrhosis related to different immune system pathways to that seen outside of the gut. This provides new insights into gut-specific immune disturbances that predispose to complications of cirrhosis, and emphasises that a better understanding of the gut-liver axis is necessary to develop better targeted therapies.. La surveillance de l’intervalle QT a suscité beaucoup d’intérêt durant la pandémie de la COVID-19 en raison de l’utilisation de médicaments prolongeant l’intervalle QT et les préoccupations quant à la transmission virale par les électrocardiogrammes (ECG) en série. Nous avons posé l’hypothèse que la surveillance en continu de l’intervalle QT par télémétrie était associée à une meilleure détection des épisodes de prolongation de l’intervalle QT.. Nous avons introduit la télémétrie cardiaque en continu (TCC) à l’aide d’un algorithme de surveillance automatisée de l’intervalle QT dans nos unités de COVID-19. Les mesures automatisées quotidiennes de l’intervalle QT corrigé (auto-QTc) en fonction de la fréquence cardiaque maximale ont été enregistrées. Nous avons comparé la proportion des épisodes de prolongation marquée de l’intervalle QTc (QTc long), définie par un intervalle QTc ≥ 500 ms, chez les patients montrant une suspicion de COVID-19 ou ayant la COVID-19 qui avaient été admis avant et après la mise en place de la TCC (groupe témoin. La surveillance en continu de l’intervalle QT est supérieure à la norme de soins dans la détection des épisodes de QTc long et exige peu d’ECG. La réponse clinique aux épisodes de QTc long est sous-optimale.. Exposure to a model wildfire air pollution source modifies cardiovascular responses to HC challenge, suggesting air pollution sensitizes the body to systemic triggers.. Though the majority of HIV-infected adults who were on HAART had shown viral suppression, the rate of suppression was sub-optimal according to the UNAIDS 90-90-90 target to help end the AIDS pandemic by 2020. Nonetheless, the rate of immunological recovery in the study cohort was low. Hence, early initiation of HAART should be strengthened to achieve good virological suppression and immunological recovery.. Dust in Egyptian laying hen houses contains high concentrations of microorganisms and endotoxins, which might impair the health of birds and farmers when inhaled. Furthermore, laying hens in Egypt seem to be a reservoir for ESBL-producing Enterobacteriaceae. Thus, farmers are at risk of exposure to ESBL-producing bacteria, and colonized hens might transmit these bacteria into the food chain.. The lack of significant differences in the absolute changes and relative ratios of injury and repair biomarkers by contrast-associated AKI status suggests that the majority of mild contrast-associated AKI cases may be driven by hemodynamic changes at the kidney.. Most comparisons for different outcomes are based on very few studies, mostly low-powered, with an overall low CoE. Thus, the available evidence is considered insufficient to either support or refute CH effectiveness or to recommend one ICM over another. Therefore, further well-designed, larger RCTs are required.. PROSPERO database Identifier: CRD42016041953.. Untouched root canal at cross-section perimeter, the Hero 642 system showed 41.44% ± 5.62% and Reciproc R40 58.67% ± 12.39% without contact with instruments. Regarding the untouched area, Hero 642 system showed 22.78% ± 6.42% and Reciproc R40 34.35% ± 8.52%. Neither instrument achieved complete cross-sectional root canal debridement. Hero 642 system rotary taper 0.02 instruments achieved significant greater wall contact perimeter and area compared to reciprocate the Reciproc R40 taper 0.06 instrument.. Hero 642 achieved higher wall contact perimeter and area but, regardless of instrument size and taper, vital pulp during.

La evaluación de riesgo es importante para predecir los resultados postoperatorios en pacientes con cáncer gastroesofágico. Este estudio de cohortes tuvo como objetivo evaluar los cambios en la composición corporal durante la quimioterapia neoadyuvante e investigar su asociación con complicaciones postoperatorias. MÉTODOS: Los pacientes consecutivos con cáncer gastroesofágico sometidos a quimioterapia neoadyuvante y cirugía con intención curativa entre 2016 y 2019, identificados a partir de una base de datos específica, se incluyeron en el estudio. Se utilizaron las imágenes de tomografía computarizada, antes y después de la quimioterapia neoadyuvante, para evaluar el índice de masa muscular esquelética, la sarcopenia y el índice de grasa visceral y subcutánea.. In this in vitro premature infant lung model, HF oscillation of BCPAP was associated with improved CO. Our results showed that HPC significantly promotes neurogenesis after MCAO and ameliorates neuronal injury.. Inflammatory markers are highly related to signs of systemic hypoperfusion in CS. Moreover, high PCT and IL-6 levels are associated with poor prognosis.. These findings indicate that Tetrapleura tetraptera fruit has a protective potential against stroke through modulation of redox and electrolyte imbalances, and attenuation of neurotransmitter dysregulation and other neurochemical dysfunctions. Tetrapleura tetraptera fruit could be a promising source for the discovery of bioactives for stroke therapy.

Diabetes mellitus type 2 (T2D) is a group of genetically heterogeneous metabolic disorders whose frequency has gradually risen worldwide. Diabetes mellitus Type 2 (T2D) has started to achieve a pandemic level, and it is estimated that within the next decade, cases of diabetes might get double due to increase in aging population. Diabetes is rightly called the 'silent killer' because it has emerged to be one of the major causes, leading to renal failure, loss of vision; besides cardiac arrest in India. Thus, a clinical requirement for the oral drug molecules monitoring glucose homeostasis appears to be unmet. GPR119 agonist, a family of G-protein coupled receptors, usually noticed in β-cells of pancreatic as well as intestinal L cells, drew considerable interest for type 2 diabetes mellitus (T2D). GPR119 monitors physiological mechanisms that enhance homeostasis of glucose, such as glucose-like peptide-1, gastrointestinal incretin hormone levels, pancreatic beta cell-dependent insulin secretion and glucose-dependent insulinotropic peptide (GIP). In this manuscript, we have reviewed the work done in the last five years (2015-2020) which gives an approach to design, synthesize, evaluate and study the structural activity relationship of novel GPR119 agonist-based lead compounds. Our article would help the researchers and guide their endeavours in the direction of strategy and development of innovative, effective GPR119 agonist-based compounds for the management of diabetes mellitus type 2.

Based on non-clinical data, it is expected that azilsartan, an angiotensin II receptor blocker, will help improve insulin resistance in addition to its hypotensive action. The present study is aimed to explore the effect of azilsartan compared to telmisartan on insulin sensitivity in hypertensive patients in the clinical setting.. This multicenter, randomized, open-label, parallel-group exploratory study was conducted in Japan. We randomized adult patients (≥20 years old) with grade I or II essential hypertension and coexisting type 2 diabetes (1:1) to receive either oral azilsartan (20 mg/day;17 patients) or telmisartan (40 mg/day;16 patients) for 12 weeks. The primary endpoint was the change in the homeostasis model assessment ratio of insulin resistance (HOMA-R) from the baseline at the end of the treatment period. We also evaluated its safety and efficacy on other diabetes-related variables and blood pressure.. The mean changes in HOMA-R at the end of treatment were 0.22 (95% CI, -1.09-1.52) in the azilsartan group and -0.23 (95% CI, -0.72-0.27) in the telmisartan group. We found no clinically remarkable changes between the groups in diabetes-related variables such as fasting blood glucose, fasting insulin, HbA1c (NGSP), HOMA-β, or 1,5-anhydroglucitol. Reductions in clinic systolic and diastolic blood pressure were observed at week 4 and the reduced levels were maintained throughout the treatment period in both groups. No serious treatment-emergent adverse events (TEAEs) were observed. Only one drug-related TEAE (mild decrease in blood pressure) was reported in one patient in the azilsartan group.. Neither azilsartan nor telmisartan had any clinically remarkable effects on insulin resistance parameters when administered for 12 weeks to patients with grade I or II essential hypertension and coexisting type 2 diabetes mellitus. Azilsartan (20 mg/day) and telmisartan (40 mg/day) exerted comparable antihypertensive effects.. ClinicalTrials.gov NCT02079805.

Non-clinical study data suggest that DS-8500a, a G protein-coupled receptor 119 agonist, exhibits antidiabetic activity, inhibition of some transporters and induction of cytochrome P450 (CYP) 3A. Statins are substrates for some transporters and CYP3A that may be coadministered with DS-8500a in clinical practice.. To determine the potential effects of DS-8500a on the pharmacokinetics of statins, we evaluated the effects of repeated oral administration of DS-8500a 75 mg on the pharmacokinetics of rosuvastatin and atorvastatin in healthy adults.. We performed two single-center, open-label, single-sequence studies. In Study I, subjects received single-dose rosuvastatin 10 mg (Period A) and DS-8500a 75 mg once daily + single-dose rosuvastatin 10 mg (Period B). In Study II, subjects received single-dose atorvastatin 10 mg (Period A) and DS-8500a 75 mg once daily + single-dose atorvastatin 10 mg (Period B). Primary pharmacokinetic endpoints were maximum plasma concentration (C. In Study I, the C. Multiple doses of DS-8500a increased exposure to rosuvastatin and atorvastatin. This short-term study suggests that the impact of DS-8500a coadministration on atorvastatin exposure is limited and may not be clinically relevant. Nevertheless, caution may be necessary when patients are coadministered rosuvastatin with DS-8500a. CLINICALTRIALS.. NCT03699774.. JapicCTI-152878.

G protein-coupled receptor 119 (GPR119) is a promising target for the treatment of type 2 diabetes mellitus (T2DM), as both insulin and glucagon-like peptide-1 secretion can be promoted with a single drug. We compared the efficacy and safety of the GPR119 agonist DS-8500a with placebo and sitagliptin 50 mg in Japanese patients with T2DM.. DS-8500a demonstrated dose-dependent HbA1c lowering compared with placebo at week 12: change from baseline - 0.23% (p = 0.0173), - 0.37% (p = 0.0001), and - 0.44% (p < 0.0001) in the 25-mg, 50-mg, and 75-mg groups, respectively. At 50- and 75-mg doses, DS-8500a significantly lowered FPG, glucose AUC. DS-8500a was well tolerated and demonstrated significant glucose-lowering effects and favorable changes in lipid profiles up to 12 weeks in Japanese patients with T2DM.. Daiichi Sankyo Co. Ltd.

We evaluated the efficacy and safety of DS-8500a as add-on therapy to sitagliptin in Japanese type 2 diabetes mellitus patients.. This multicenter, randomized, double-blind, placebo-controlled, phase 2 trial randomized patients aged ≥20 years with hemoglobin A1c ≥7.0% and <9.0%, and inadequate glycemic control with sitagliptin 50-mg monotherapy to receive 25 or 75 mg DS-8500a, or a placebo, orally. The primary end-point was change from baseline to day 28 in 24-h weighted mean glucose. Secondary end-points included change from baseline in fasting plasma glucose, 2-h postprandial plasma glucose and lipid profiles.. Overall, 29, 28 and 27 patients in the placebo, 25- and 75-mg groups, respectively, were analyzed. A significant dose-dependent reduction was observed in 24-h weighted mean glucose (linear: P = 0.0006, saturated at 25 mg: P = 0.0003, responded from 75 mg: P = 0.0176) when compared with the placebo (25 mg: -13.19 mg/dL [-0.73 mmol/L], P = 0.0044 vs placebo and 75 mg: -16.12 mg/dL [-0.89 mmol/L], P = 0.0006 vs placebo). A significant reduction in fasting plasma glucose at 75 mg vs placebo was observed (P < 0.001). At 25 and 75 mg, significant reductions of 2-h postprandial plasma glucose (after breakfast), total cholesterol, low-cholesterol and triglycerides were observed (all P < 0.05), with a (non-significant) trend towards increased high-density lipoprotein cholesterol. Both doses of DS-8500a were well tolerated. There were no significant treatment-emergent adverse events leading to discontinuation during the study.. DS-8500a was well tolerated, and showed significant glycemic benefits and favorable changes in lipid profile in Japanese type 2 diabetes mellitus patients with inadequate glycemic control with sitagliptin therapy.

Angiotensin receptor blockers (ARBs) are preferred antihypertensive therapies in patients with type 2 diabetes mellitus (T2DM). Azilsartan medoxomil (AZL-M) is a potent ARB for the treatment of stages 1-2 hypertension. We compared the efficacy, safety, and metabolic effects of AZL-M to both valsartan (VAL) and olmesartan (OLM), separately in patients with impaired fasting glucose (prediabetes mellitus) and T2DM.. A pooled analysis of 3821 patients from three separate randomized placebo-controlled trials comparing the effects of AZL-M (40 and 80 mg), OLM (40 mg), VAL (320 mg), and placebo on changes in ambulatory and clinic blood pressure (BP) among patients with hypertension and prediabetes mellitus or T2DM was performed. Two analysis pools were created to facilitate comparisons: Pool A included patients who received placebo, AZL-M or OLM and Pool B included those who received AZL-M or VAL. Within each pool, patients were stratified by glycemic subgroups (normoglycemic, prediabetes mellitus, or T2DM) based on hemoglobin A1c values. Changes from baseline in both 24-h and clinic SBP were the primary efficacy assessments.. Baseline 24-h mean SBPs were approximately 145 and 146 mmHg in the prediabetes mellitus and T2DM subgroups, respectively; corresponding clinic SBPs were approximately 158 and 159 mmHg. Baseline hemoglobin A1c values for each subgroup (both pools) were normoglycemic, 5.3%; prediabetes mellitus, 6.0%; and T2DM, 6.9%. Changes from baseline in 24-h or clinic SBP were significantly greater with AZL-M, 80 mg compared with either OLM 40 mg or VAL 320 mg in all subgroups in each pool. Safety and tolerability were similar among the active treatment and placebo subgroups.. These analyses indicate that AZL-M, 80 mg/day lowers SBP by a greater magnitude than OLM or VAL at maximally approved doses in patients with prediabetes mellitus and T2DM. These findings have important clinical implications for this high-risk patient group.

GPR119 receptor agonists improve glucose metabolism and alter gut hormone profiles in animal models and healthy subjects. We therefore investigated the pharmacology of GSK1292263 (GSK263), a selective GPR119 agonist, in two randomized, placebo-controlled studies that enrolled subjects with type 2 diabetes. Study 1 had drug-naive subjects or subjects who had stopped their diabetic medications, and Study 2 had subjects taking metformin. GSK263 was administered as single (25-800 mg; n = 45) or multiple doses (100-600 mg/day for 14 days; n = 96). Placebo and sitagliptin 100 mg/day were administered as comparators. In Study 1, sitagliptin was co-administered with GSK263 or placebo on Day 14 of dosing. Oral glucose and meal challenges were used to assess the effects on plasma glucose, insulin, C-peptide, glucagon, peptide tyrosine-tyrosine (PYY), glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP). After 13 days of dosing, GSK263 significantly increased plasma total PYY levels by ∼ five-fold compared with placebo, reaching peak concentrations of ∼ 50 pM after each of the three standardized meals with the 300 mg BID dose. Co-dosing of GSK263 and metformin augmented peak concentrations to ∼ 100 pM at lunchtime. GSK263 had no effect on active or total GLP-1 or GIP, but co-dosing with metformin increased post-prandial total GLP-1, with little effect on active GLP-1. Sitagliptin increased active GLP-1, but caused a profound suppression of total PYY, GLP-1, and GIP when dosed alone or with GSK263. This suppression of peptides was reduced when sitagliptin was co-dosed with metformin. GSK263 had no significant effect on circulating glucose, insulin, C-peptide or glucagon levels. We conclude that GSK263 did not improve glucose control in type 2 diabetics, but it had profound effects on circulating PYY. The gut hormone effects of this GPR119 agonist were modulated when co-dosed with metformin and sitagliptin. Metformin may modulate negative feedback loops controlling the secretion of enteroendocrine peptides.. Clinicaltrials.gov NCT01119846 Clinicaltrials.gov NCT01128621.

The application of QSAR along with other in silico tools like molecular docking, and molecular dynamics provide a lot of promise for finding new treatments for life-threatening diseases like Type 2 diabetes mellitus (T2DM). The present study is an attempt to develop Monte Carlo algorithm-based QSAR models using freely available CORAL software. The experimental data on the α-amylase inhibition by a series of benzothiazole-linked hydrazone/2,5-disubstituted-1,3,4-oxadiazole hybrids were selected as endpoint for the model generation. Initially, a total of eight QSAR models were built using correlation intensity index (CII) as a criterion of predictive potential. The model developed from split 6 using CII was the most reliable because of the highest numerical value of the determination coefficient of the validation set (

Regional differences in the profile and treatment strategies of patients with cardiometabolic diseases have been studied in several different countries. The Cardio-Vascular and metabolic treatments in Canada: Assessment of REal-life therapeutic value (CV-CARE) registry was designed to evaluate patient profiles and medical management of cardiometabolic diseases in routine clinical care settings across Canada. Primary objectives were to (1) evaluate regional variability of patient profiles with cardiometabolic disease(s) and (2) assess treatment differences of patients treated for type 2 diabetes (T2D), hypercholesterolemia (HCh), and hypertension (HTN) across Canada.. CV-CARE is a multi-center, observational, prospective registry that enrolled Canadian patients treated with metformin-extended release (MetER) for T2D, colesevelam (C) for HCh, azilsartan (AZI) for mild-to-moderate essential HTN and azilsartan/chlorthalidone (AZI/CHL) for severe, essential HTN. Patient characteristics and treatments were assessed at baseline.. The registry enrolled 6960 patients, with a total of 4194 patients making up the primary analysis population [MetER (n=995); C (n=1639); AZI (n=1364); AZI/CHL (n=498)]. First-line use of MetER was more common in British Columbia (BC; 45.5%) compared to Ontario (ON; 29.8%), and Quebec (QC; 12.9%). C treatment for HCh was used as monotherapy most readily in BC (68.7%) compared with QC (59.7%) and ON (35.8%). Dual action of low-density lipoprotein cholesterol and hemoglobin A1c reduction was the predominant reason for C add-on therapy (46.8%), with highest usage seen in ON (62.9%). AZI treatment for HTN was most frequently used in BC (43.8%), and AZI/CHL was most commonly used in ON (12.0%). First-line use of AZI was more common in QC (50%) vs. ON (34.9%) and BC (24.1%). The primary reason for switching to AZI and AZI/CHL from prior treatment was lack of efficacy across provinces.. This is the first regional description of the CV-CARE cohort. Significant variations in both baseline profile and treatments were observed which could have an impact on long-term outcomes.

The new class of PPARgamma non-TZD agonist originally derived from the backbone of anti-hypertensive Fimasartan, BR101549, was identified as a potential lead for anti-diabetic drug development. The X-ray crystallography of BR101549 with PPARgamma ligand binding domain (LBD) revealed unique binding characteristics versus traditional TZD full agonists. The lead candidate, BR101549, has been found activating PPARgamma to the level of Pioglitazone in vitro and indeed has demonstrated its effects on blood glucose control in mouse proof-of-concept evaluation. The attempts to improve its metabolic stability profile through follow-up SAR including deuterium incorporation have been also described.

As a potential treatment of type 2 diabetes, a novel PPARγ non-TZD full agonist, compound 18 (BR102375) was identified from the original lead BR101549 by the SAR efforts of the labile metabolite control through bioisosteres approach. In vitro assessments of BR102375 demonstrated its activating potential of PPARγ comparable to Pioglitazone as well as the induction of related gene expressions. Further in vivo evaluation of BR102375 in diabetic rodent models successfully proved its glucose lowering effect as a potential antidiabetic agent, but the anticipated suppression of weight gain was not evident. The X-ray co-crystal analysis of BR102375-PPARγ LBD unexpectedly revealed binding modes totally different from those of BR101549, which was found, instead, closely resembled to those of TZD full agonists.

Diabetes mellitus (DM), a chronic multifarious metabolic disorder resulting from impaired glucose homeostasis has become one of the most challenging diseases with severe life threat to public health. The inhibition of α-glucosidase, a key carbohydrate hydrolyzing enzyme, could serve as one of the effective methodology in both preventing and treating diabetes through controlling the postprandial glucose levels and suppressing postprandial hyperglycemia. In this context, three series of diamine-bridged bis-coumarinyl oxadiazole conjugates were designed and synthesized by one-pot multi-component methodology. The synthesized conjugates (4a-j, 5a-j, 6a-j) were evaluated as potential inhibitors of glucosidases. Compound 6f containing 4,4'-oxydianiline linker was identified as the lead and selective inhibitor of α-glucosidase enzyme with an IC

GPR119 (G-protein coupled receptor 119) has been shown to be highly expressed in the lower small intestinal and colorectal L-cells and pancreatic β-cells, and mediates intracellular cAMP concentration, glucagon like peptide (GLP-1) secretion, and glucose stimulated insulin secretion (GSIS). As the next generation for the treatment of type 2 diabetes mellitus (T2DM), GPR119 agonist has been intensively studied by pharmaceutical companies and a lot of patents have been applied by them. In such highly competitive condition, biological differentiation and to find an advantage among GPR119 agonists were necessary to proceed the candidate compound in further clinical investigation. Firuglipel (DS-8500a) is an orally available GPR119 agonist synthesized in DAIICHI SANKYO CO., LTD (DS). It was originated from DS-chemical library and optimized in the aspect of bioavailability and safety. Firuglipel had a higher intrinsic activity (IA) of the production of intracellular cAMP in human GPR119 expressing CHO-K1 cells than those of other GPR119 agonists studied. The level of IA in each GPR119 agonist was correlated with the existence of agonist conformer. In parallel with the study for the differentiation from other GPR119 agonists, we compared firuglipel with dipeptidyl peptide-4 (DPP-4) inhibitor in NONcNZO10/LtJ mice and evaluated their combination in streptozotocin (STZ) treated C57BL/6J mice to clarify future positioning among anti-diabetics therapy. These pharmacological studies illustrated here can draw out a clinical value of compound and expected to lead the production of first-in-class agent in pharmaceutical companies.

Discovery of α-glucosidase inhibitors has been actively pursued with the aim to develop therapeutics for the treatment of type-II diabetes mellitus and the other carbohydrate mediated disease. In continuation of our drug discovery research on potential antidiabetic agents, we synthesized novel tris-indole-oxadiazole hybrid analogs (1-21), structurally characterized by various spectroscopic techniques such as

In type 2 diabetes mellitus (T2DM) patients, the gradual loss of pancreatic β-cell function is a characteristic feature of disease progression that is associated with sustained hyperglycemia. Recently, G protein-coupled receptor 119 (GPR119) has been identified as a promising anti-diabetic therapeutic target. It is predominantly expressed in pancreatic β-cells, directly promotes glucose stimulated insulin secretion and indirectly increases glucagon-like peptide 1 (GLP-1) levels reducing appetite and food intake. Activation of GPR119 leads to insulin release in β-cells by increasing intracellular cAMP. Here, we identified a novel structural class of small-molecule GPR119 agonists, HD0471042, consisting of substituted a 3-isopropyl-1,2,4-oxadiazol-piperidine derivative with promising potential for the treatment of T2DM. The GPR119 agonist, HD0471042 increased intracellular cAMP levels in stably human GPR119 expressing CHO cell lines and HIT-T15 cell lines, hamster β-cell line expressing endogenously GPR119. HD0471042, significantly elevated insulin release in INS-1 cells of rat pancreatic β-cell line. In in vivo experiments, a single dose of HD0471042 improved glucose tolerance. Insulin and GLP-1 level were increased in a dose-dependent manner. Treatment with HD0471042 for 6 weeks in diet induced obesity mice and for 4 weeks in ob/ob and db/db mice improved glycemic control and also reduced weight gain in a dose-dependent manner. These data demonstrate that the novel GPR119 agonist, HD0471042, not only effectively controlled glucose levels, but also had an anti-obesity effect, a feature observed with GLP-1. We therefore suggest that HD0471042 represents a new type of anti-diabetes agent with anti-obesity potential for the effective treatment of type 2 diabetes.

We have shown that Goto-Kakizaki (GK) rats, a lean model of type 2 diabetes, develop significant cerebrovascular remodeling by the age of 18 weeks, which is characterized by increased media thickness and matrix deposition. Although early glycemic control prevents diabetes-mediated remodeling of the cerebrovasculature, whether the remodeling can be reversed is unknown. Given that angiotensin II type 1 receptor blockers reverse pathologic vascular remodeling and function independent of changes in blood pressure in other vascular beds, we hypothesized that azilsartan medoxomil, a new angiotensin II type 1 receptor blocker, is vasculoprotective by preventing and reversing cerebrovascular remodeling in diabetes. Control Wistar and diabetic GK rats (n = 6-8 per group) were treated with vehicle (water) or azilsartan medoxomil (3 mg/kg/d) from the age of 14 to 18 or 18 to 22 weeks before or after vascular remodeling is established, respectively. Blood glucose and blood pressure were monitored and middle cerebral artery structure and function were evaluated using pressurized arteriography. Blood glucose was higher in GK rats compared with Wistar rats. Azilsartan treatment lowered blood glucose in diabetic animals with no effect on blood pressure. Diabetic animals exhibited lower myogenic tone, increased wall thickness, and cross-sectional area compared with control group animals, which were corrected by azilsartan treatment when started at the onset of diabetes or later after vascular remodeling is established. Azilsartan medoxomil offers preventive and therapeutic vasculoprotection in diabetes-induced cerebrovascular remodeling and myogenic dysfunction and this is independent of blood pressure.

Agonism of GPR119 is viewed as a potential therapeutic approach for the treatment of type II diabetes and other elements of metabolic syndrome. During progression of a previously disclosed candidate 1 through mice toxicity studies, we observed tonic-clonic convulsions in several mice at high doses. An in vitro hippocampal brain slice assay was used to assess the seizure liability of subsequent compounds, leading to the identification of an aryl sulfone as a replacement for the 3-cyano pyridyl group. Subsequent optimization to improve the overall profile, specifically with regard to hERG activity, led to alkyl sulfone 16. This compound did not cause tonic-clonic convulsions in mice, had a good pharmacokinetic profile, and displayed in vivo efficacy in murine models. Importantly, it was shown to be effective in wild-type (WT) but not GPR119 knockout (KO) animals, consistent with the pharmacology observed being due to agonism of GPR119.

We describe herein the design, syntheses and structure-activity relationships (SAR) of novel zwitterionic compounds as non-thiazolidinedion (TZD) based peroxisome proliferator activated receptor (PPAR) α/γ dual agonists. In the previous report, we obtained compound 1 showing potent PPARα/γ dual agonistic activities, together with a great glucose lowering effect in the db/db mice. However, this compound possessed fatal issues such as potent cytochrome P450 (CYP)3A4 direct inhibitory activity. Thus, we carried out the medicinal optimization to improve these while maintaining the potent PPAR agonistic activity. As a result, the issues were addressed by changing the furan ring to a low lipophilic 1,3,4-oxadiazole ring. Additionally, these oxadiazole derivatives exhibited a significant decrease in plasma glucose and plasma triglyceride levels without marked weight gain.

5-(O-Perbenzoylated-β-D-glucopyranosyl)tetrazole was obtained from O-perbenzoylated-β-D-glucopyranosyl cyanide by Bu(3)SnN(3) or Me(3)SiN(3)-Bu(2)SnO. This tetrazole was transformed into 5-ethynyl- as well as 5-chloromethyl-2-(O-perbenzoylated-β-D-glucopyranosyl)-1,3,4-oxadiazoles by acylation with propiolic acid-DCC or chloroacetyl chloride, respectively. The chloromethyl oxadiazole gave the corresponding azidomethyl derivative on treatment with NaN(3). These compounds were reacted with several alkynes and azides under Cu(I) catalysed cycloaddition conditions to give, after removal of the protecting groups by the Zemplén protocol, β-D-glucopyranosyl-1,3,4-oxadiazolyl-1,2,3-triazole, β-D-glucopyranosyl-1,2,3-triazolyl-1,3,4-oxadiazole, and β-D-glucopyranosyl-1,3,4-oxadiazolylmethyl-1,2,3-triazole type compounds. 5-Phenyltetrazole was also transformed under the above conditions into a series of aryl-1,3,4-oxadiazolyl-1,2,3-triazoles, aryl-1,2,3-triazolyl-1,3,4-oxadiazoles, and aryl-1,3,4-oxadiazolylmethyl-1,2,3-triazoles. The new compounds were assayed against rabbit muscle glycogen phosphorylase b and the best inhibitors had inhibition constants in the upper micromolar range (2-phenyl-5-[1-(β-D-glucopyranosyl)-1,2,3-triazol-4-yl]-1,3,4-oxadiazole 36: K(i)=854μM, 2-(β-D-glucopyranosyl)-5-[1-(naphthalen-2-yl)-1,2,3-triazol-4-yl]-1,3,4-oxadiazole 47: K(i)=745μM).

The novel hypoglycemic agent, YM440 ((Z)-1,4-bis{4-[(3,5-dioxo-1,2,4-oxadiazolidin-2-yl) methyl] phenoxy}but-2-ene) is a ligand of the peroxisome proliferator-activated receptor, (PPAR) gamma. YM440 has been shown to counteract insulin resistance in diabetic rodent models. However, it is not clear whether this compound has a significant effect on hyperlipidemia in vivo. Hyperlipidemia has been reported to be a risk factor for the early development of renal disease. The aim of this study is to examine the effects of chronic treatment with YM440 on hyperlipidemia and renal injury in obese Zucker fatty (ZF) rats. Treatment of 8-week-old ZF rats with YM440 (100 mg/kg/day) for 16 weeks decreased plasma triglyceride and cholesterol concentrations. YM440 markedly reduced the rate of progression of both albuminuria and proteinuria. YM440 normalized urinary N-acetyl-beta-D-glucosaminidase (NAG) activity, which is a marker for renal proximal tubular damage, and ameliorated the rise in systolic blood pressure compared to the vehicle control. YM440 also blocked the development of nephromegaly. Histological analyses revealed that both glomerular area expansion and tubular cast accumulation gradually lessened in YM440-treated ZF rats. Regression analyses between the plasma triglyceride levels and the renal parameters (urinary protein excretion and albumin excretion) indicated that the renal parameters correlated positively with the plasma triglyceride levels. In conclusion, the hypolipidemic effects of YM440 prevent renal injury in ZF rats. YM440 might be useful for preventing the early development of diabetic nephropathy in subjects with type 2 diabetes by ameliorating metabolic control problems.

A series of 1,2,4-oxadiazolidine-3,5-diones was synthesized and evaluated as oral antihyperglycemic agents in the obese insulin resistant db/db and ob/ob mouse - the two models for Type 2 diabetes mellitus. The majority of the prepared methoxy- and ethoxy-linked oxazole 1,2,4-oxadiazolidine-3,5-diones normalized plasma glucose levels at the 100 mg kg(-1) oral dose in the db/db diabetic mouse model, and several amongst them reduced the glucose levels at the 20 mg kg(-1) oral dose. The most potent compounds in the db/db mouse model were also active in the ob/ob mouse model normalizing the plasma glucose levels at the 20 mg kg(-1) oral dose. The trifluoromethoxy analog 32 was the most active compound of the series, reducing significantly the plasma glucose levels at the 5 mg kg(-1) oral dose. Oxadiazole-tailed 1,2,4-oxadiazolidine-3,5-diones were also active in both the db/db and ob/ob diabetic mouse models normalizing plasma glucose levels at the 100 mg kg(-1) oral dose.

To determine the relationship between hypoglycemic activity and body weight gain induced by insulin sensitizers, we compared the effects of thiazolidinedione analogs (troglitazone and pioglitazone) and the oxadiazolidinedione analog (Z)-1,4-bis4[(3,5-dioxo-1,2,4-oxadiazolidin-2-yl)methyl]phen oxy¿but-2-ene (YM440) in diabetic db/db mice. Oral treatment with YM440(100 mg/kg) for 28 days decreased the blood glucose concentration (control v YM440, 418 +/- 12 v243 +/- 44 mg/dL). The hypoglycemic activity of this agent was comparable to that of troglitazone (300 mg/kg) and pioglitazone (100 mg/kg). There were no changes in food intake among the groups. Troglitazone and pioglitazone, but not YM440, significantly increased body weight gain during treatment (control, 7.2 +/- 0.5 g; YM440, 7.5 +/- 0.8 g; troglitazone, 10.9 +/- 0.8 g; and pioglitazone, 14.5 +/- 1.1 g). To further assess whether the increase in body weight by troglitazone or pioglitazone was due to adipogenesis, the weight of intraabdominal fat tissue (epididymal, retroperitoneal, and perirenal) was determined. There were no differences in the total weight of visceral fat between the control and YM440 treatment (3.53 +/- 0.23 and 3.60 +/- 0.16 g). In contrast, troglitazone and pioglitazone significantly increased the fat weight (4.31 +/- 0.13 and 4.66 +/- 0.19 g). Thiazolidinediones are known as ligands for peroxisome proliferator-activated receptor gamma (PPARgamma), a nuclear receptor responsible for adipogenesis. Troglitazone and pioglitazone activated PPARgamma and increased triglyceride accumulation and mRNA expression of fatty acid-binding protein (FABP) in 3T3-L1 cells. However, YM440 had no effect on these indices for adipocyte differentiation. These results suggest that the mechanism is different for the hypoglycemic action of YM440 versus the thiazolidinediones. YM440 ameliorates hyperglycemia without changing PPARgamma activity, adipocyte differentiation, or fat weight. Thus, YM440 could be a useful hypoglycemic agent for the treatment of non-insulin-dependent diabetes mellitus (NIDDM) without affecting body weight.
