apigenin and Diabetes-Mellitus--Type-2

Diabetes is a fast growing chronic metabolic disorder around the world. Dipeptidyl peptidase-4 (DPP-4) is a new promising target during type 2 diabetes glycemic control. Thus, a number of potent DPP-4 inhibitors were developed and play a rapidly evolving role in the management of type 2 diabetes in recent years. This article reviews the development of synthetic and natural DPP-4 inhibitors from 2012 to 2017 and provides their physico-chemical properties, biological activities against DPP-4 and selectivity over dipeptidyl peptidase-8/9. Moreover, the glucose-lowering mechanisms and the active site of DPP-4 are also discussed. We also discuss strategies and structure-activity relationships for identifying potent DPP-4 inhibitors, which will provide useful information for developing potent DPP-4 drugs as type 2 diabtes treatments.

This study aimed at assessing the effects of chamomile tea consumption on glycemic control and serum lipid profile in patients with type 2 diabetes mellitus (T2DM).. This single-blind randomized controlled clinical trial was conducted on 64 individuals with T2DM (males and females) aged between 30 and 60 years. The intervention group (n = 32) consumed chamomile tea (3 g/150 mL hot water) three times per day immediately after meals for 8 weeks. The control group (n = 32) followed a water regimen for the same intervention period. Fasting blood samples, anthropometric measurements, and 3-day, 24-h dietary recalls were collected at the baseline and at the end of the trial. Data were analyzed by independent t test, paired t test, Pearson correlation test, and analysis of covariance.. Chamomile tea significantly decreased concentration of HbA1C (p = 0.03), serum insulin levels (p < 0.001), homeostatic model assessment for insulin resistance (p < 0.001), total cholesterol (p = 0.001), triglyceride (p < 0.001), and low-density lipoprotein cholesterol (p = 0.05) compared with control group. No significant changes were shown in serum high-density lipoprotein cholesterol levels in both groups.. Chamomile tea has some beneficial effects on glycemic control and serum lipid profile in T2DM patients.

An abundant literature suggests that obesity-associated with taking a high fat diet is related to an elevated risk of type 2 diabetes and metabolic syndrome. However, metabolic disorders may be involved in the induction of the anxiogenic-like symptoms. The current study was designed to elucidate the mechanisms by which a high fat diet (HFD) can cause several complications in the WISTAR rats (
