curcumin and allicin

The aim of this review is to evaluate the different medicinal interventions available for the management of oral submucous fibrosis (OSF).. We conducted a comprehensive electronic search on PubMed, Web of Science, and Cochrane Library databases for articles related to OSF patients treated with medications from December 2011 to September 2022. GRADE system was used to evaluate the evidence quality. The reporting of the systematic review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The main outcomes were the improvement of maximum mouth opening, burning sensation, cheek flexibility, and tongue protrusion.. Twenty-nine randomized controlled trials (RCTs), five clinical trials (CCTs) were included, and the use of drugs for OSF treatment were evaluated. Drugs like steroids, hyaluronidase, pentoxifylline, lycopene, curcumin, dpirulina, aloe vera, omega3, oxitard, allicin, colchicine have been used. It was found that drugs with evidence high quality were salvia miltiorrhiza combined with triamcinolone acetonide, lycopene, pentoxifylline, curcumin, and aloe vera, and those with evidence moderate quality were allicin, colchicine, omega 3, and oxitard.. Based on the results of our comprehensive analysis, for long-term treatment, we found lycopene with low side effects, whereas for relieving the symptoms of severe burning sensation, aloe vera is the most effective. Although the recent review has made some progress, drug therapy for OSF remains unclear, and more high-quality RCTs are needed to identify better treatments for OSF.

The blockade of the progression or onset of pathological events is essential for the homeostasis of an organism. Some common pathological mechanisms involving a wide range of diseases are the uncontrolled inflammatory reactions that promote fibrosis, oxidative reactions, and other alterations. Natural plant compounds (NPCs) are bioactive elements obtained from natural sources that can regulate physiological processes. Inflammation is recognized as an important factor in the development and evolution of chronic renal damage. Consequently, any compound able to modulate inflammation or inflammation-related processes can be thought of as a renal protective agent and/or a potential treatment tool for controlling renal damage. The objective of this research was to review the beneficial effects of bioactive natural compounds on kidney damage to reveal their efficacy as demonstrated in clinical studies.. This systematic review is based on relevant studies focused on the impact of NPCs with therapeutic potential for kidney disease treatment in humans.. Clinical studies have evaluated NPCs as a different way to treat or prevent renal damage and appear to show some benefits in improving OS, inflammation, and antioxidant capacity, therefore making them promising therapeutic tools to reduce or prevent the onset and progression of KD pathogenesis.. This review shows the promising clinical properties of NPC in KD therapy. However, more robust clinical trials are needed to establish their safety and therapeutic effects in the area of renal damage.

Gastric cancer is one of the most common causes of cancer-related death worldwide. Medicinal plants are one of the main sources for discovery of new pharmacological agents especially for treatment of cancers. The aim of the present study is to review pharmacotherapeutic aspects of three mostly studied phytochemicals including curcumin, quercetin, and allicin for management of gastric cancer.. Scopus, PubMed, Web of Science, and Google Scholar were searched for the effects of curcumin, quercetin, allicin, and their analogs in gastric cancer. Data were collected up to November 2015. The search terms were "curcumin," "quercetin," "allicin," and "gastric cancer" or "cancer.". Curcumin demonstrated anti-angiogenic, anti-proliferative, anti-metastatic, pro-apoptotic, and anti-helicobacter activities. Quercetin inhibited cell growth and induced apoptosis, necrosis, and autophagy as well as anti-Helicobacter activity. Allicin showed apoptotic and anti-Helicobacter properties. All three natural compounds had low bioavailability.. Although preclinical studies demonstrated the activity of curcumin, quercetin, and allicin in gastric cancer, clinical trials are needed to confirm their effectiveness. Applying their possible synergistic action and suitable drug delivery system in clinical studies can be also an attractive approach with the purpose of finding new extremely efficient anti-gastric cancer agents. Curcumin, quercetin, and allicin seem to be good candidates for management of gastric cancer through their pro-apoptotic, anti-proliferative, and anti-helicobacter activities.

Certain industrial chemicals and food contaminants have been demonstrated to possess neurotoxic activity and have been suspected to cause brain-related disorders in humans. Acrylamide (ACR), a confirmed neurotoxicant, can be found in trace amount in commonly consumed human aliments as a result of food processing or cooking. This discovery aroused a great concern in the public, and increasing efforts are continuously geared towards the resolution of this serious threat. The broad chemical diversity of plants may offer the resources for novel antidotes against neurotoxicants. With the goal of attenuating neurotoxicity of ACR, several plants extracts or derivatives have been employed. This review presents the plants and their derivatives that have been shown most active against ACR-induced neurotoxicity, with a focus on their origin, pharmacological activity, and antidote effects.

Medicinal plants have been known to provide the essential raw material for the majority of antiviral drugs. This study demonstrated the putative inhibitory potential of curcumin, allicin, and gingerol towards cathepsin K, COVID-19 main protease, and SARS-CoV 3 C-like protease. The pharmacokinetic properties were predicted through the SwissADME server while the corresponding binding affinity of the selected phytocompounds towards the proteins was computed using PyRx-Python Prescription 0.8 and the binding free energy were computed based on conventional molecular dynamics using LARMD server. The ADMET properties revealed all the drugs possess drug-like properties. Curcumin has the highest binding affinities with all the selected proteases while allicin has the lowest binding affinities towards the proteases. Moreover, it was observed that curcumin exhibited the highest binding free energy of -17.90 ± 0.23,  -18.21 ± 0.25, and -9.67 ± 0.08 kcal/mol for Cathepsin K, COVID-19 main protease, and SARS-CoV 3 C-like protease, respectively. Based on the activities of the phytocompounds against coronavirus target proteases involved in the viral entry as evident from the results, the study, therefore, suggests that these phytocompounds could be valuable for the development of drugs useful for the prevention of coronavirus entry and replication.Communicated by Ramaswamy H.

This study evaluated the growth performance, immunity, and jejunum morphology of chicks hatched from laying breeder hens given dietary additive supplementation, as well as chicks receiving direct antibiotic supplementation in early life. Hy-line breeder hens were allotted to 2 groups with 3 replicates. A control group (CON) was fed a basal diet, and the treatment group (CCAB) received β-carotene, curcumin, allicin, and sodium butyrate in addition to basal diet for 5 wk. Breeder-hen eggs were collected and hatched. The chicks hatched from the CON group were assigned to 2 treatments: a chick control group (cCON) and a chick treatment group (Cipro) given ciprofloxacin lactate into drinking water; the cCON group, Cipro group, and the chicks hatched from the CCAB group (cCCAB) were fed the same diet for 4 wk. The results demonstrated that there were significant differences between the CON and CCAB groups in the serum levels of IgA, IgG, IgM (triple P < 0.01), lysozyme (P < 0.05), and β-defensin (P < 0.05). The body weights of the cCCAB group's chicks increased at 1, 7, and 28 D of age (P < 0.05, P < 0.05, P < 0.01, respectively), and those of the Cipro group's chicks increased at 7 and 21 D of age (P < 0.01, P < 0.05). The tibial lengths of the cCCAB group's chicks increased at 1, 7, 14, 21, and 28 D of age (P < 0.01, P < 0.05, triple P < 0.01), and the lengths in the Cipro group increased at 7 and 14 D of age (P < 0.01, P < 0.01). Intestinal development, including intestinal length, jejunum morphology, and IgA positive cells, helps to explain these results. The breeder eggs from the CCAB group had higher IgG (P < 0.05) and IgM (P < 0.05) levels in the egg whites and higher IgA, IgG, and IgM levels (triple P < 0.01) in the egg yolks. In conclusion, β-carotene, curcumin, allicin, and sodium butyrate supplementation of laying breeder hen diets produced more advantages in growth performance and intestinal development in offspring than in chicks directly supplemented with antibiotics.

Our long-term goal is to improve chick health and reduce the use of antibiotics in the poultry industry via maternal effects. To link jejunal microbes with chicks' different immune levels and growth performance in our previous research, this study investigated jejunal microbes, jejunal inflammation, and immune responses based on a comparison between different groups. Newly hatched Hy-Line chicks were allotted into 3 groups: a chick control group (cCON), a ciprofloxacin lactate treatment group (Cipro)-the chicks of the cCON and Cipro groups were hatched from laying breeder hens given a basal diet-and a 5-wk β-carotene, curcumin, allicin, and sodium butyrate supplementation group (cCCAB), wherein chicks hatched from laying breeder hens. All groups were fed the same diet for 4 wk; the Cipro group was given ciprofloxacin lactate in drinking water continuously. At the end of the experiment, the results demonstrated that the jejunal microbes of the Cipro group showed significant changes in alpha and beta diversity, and in taxonomy at phylum and genus levels. Statistically, a total of 67 significantly enriched (P < 0.05) taxa were identified between groups by linear discriminant analysis effect size; Firmicutes was significantly enriched (P < 0.05) in the cCCAB group, 65 taxa were significantly enriched (P < 0.05) in the Cipro group, and 32 of the 65 enriched (P < 0.05) taxa were in the Proteobacteria phylum of the Cipro group. Levels of lipopolysaccharide in jejunal content, and nuclear factor kappa-B, and tumor necrosis factor-α in jejunums of the Cipro and cCCAB groups were increased (all P < 0.05) compared to those in the cCON group. There was obvious neutrophil infiltration and upregulated (all P < 0.05) IL-6 mRNA in the Cipro group jejunums compared to the cCON and cCCAB groups. The expression of PSME3 and PSME4 genes was upregulated (all P < 0.05) in the cCCAB group compared to the cCON and Cipro groups. In conclusion, ciprofloxacin lactate administration led to potential hazards in health and growth in chicks via microbial disturbances-induced jejunal inflammation, and laying breeder hens dietary supplementation with β-carotene, curcumin, allicin, and sodium butyrate could enhance jejunal immunity of their offspring via the interaction between host innate immunity selected microbial colonization and microbiota educated adaptive immunity.
