Thiazolidinedione derivatives as novel GPR120 agonists for the treatment of type 2 diabetes.

ABSTRACT: GPR120, also called FFAR4, is preferentially expressed in the intestines, and can be stimulated by long-chain free fatty acids to increase the secretion of glucagon-like peptide-1 (GLP-1) from intestinal endocrine cells. It is known that GLP-1, as an incretin, can promote the insulin secretion from pancreatic cells in a glucose-dependent manner. Therefore, GPR120 is a potential drug target to treat type 2 diabetes. In this study, thiazolidinedione derivatives were found to be novel potent GPR120 agonists. Compound 5g, with excellent agonistic activity, selectivity, and metabolic stability, improved oral glucose tolerance in normal C57BL/6 mice in a dose-dependent manner. Moreover, compound 5g exhibited anti-diabetic activity by promoting insulin secretion in diet-induced obese mice. In summary, compound 5g might be a promising drug candidate for the treatment of type 2 diabetes.

Project description:No meta-analysis has analyzed the safety and efficacy of rivoglitazone in type-2 diabetes (T2DM). We undertook this meta-analysis to address this knowledge gap. Electronic databases were searched for RCTs involving T2DM patients receiving rivoglitazone in the intervention arm, and placebo/active comparator in the control arm. The primary outcome was to evaluate changes in HbA1c. Secondary outcomes were to evaluate alterations in glucose, lipids, and adverse events. From initially screened 24 articles, data from 3 RCTs (3591 patients) that fulfilled all criteria was analzsed. HbA1c was significantly lower with standard-dose (1 mg/d) [MD-0.86% (95%CI:-1.11--0.61); P < 0.01; I2 = 87%] and high-dose (1.5-2 mg/d) [MD-0.97%(95%CI:-1.03--0.90); P < 0.01; I2 = 19%] rivoglitazone compared to placebo. When compared to pioglitazone (30-45 mg/d), HbA1c lowering was comparable with standard-dose [MD 0.05%(95%CI:-0.01 - 0.11); P = 0.08; I2 = 11%], but superior with high-dose [MD -0.11%(95%CI:-0.18- -0.04); P < 0.01; I2 = 0%] rivoglitazone. Triglycerides were significantly lower with standard-dose [MD-17.95 mg/dl (95%CI:-34.23--1.66); P = 0.03; I2 = 0%] and high-dose [MD-40.41 mg/dl (95%CI:-72.90- -7.93);P = 0.01;I2 = 71%] rivoglitazone compared to placebo. Adiponectin significantly improved with standard-dose [MD 7.94 ng/ml (95%CI: 5.48-10.39); P < 0.01;I2 = 98%] and high-dose [MD 13.82 ng/ml (95%CI: 8.16-19.48); P < 0.01; I2 = 100%] rivoglitazone compared to placebo. hsCRP was significantly lower with standard-dose [MD -1.00 mg/L (95% CI: -1.20 - -0.80); P < 0.01; I2 = 6%] and high-dose [MD -1.50 mg/L (95%CI:-1.59- -1.40); P < 0.01; I2 = 0%] rivoglitazone compared to placebo. Treatment-emergent adverse events with standard-dose [Risk ratio (RR) 1.16 (95%CI: 0.84 -1.60); P = 0.38; I2 = 0%] and high-dose [RR1.34 (95%CI: 0.99-1.83); P = 0.06; I2 = 0%] rivoglitazone was comparable to placebo. Severe adverse events with standard-dose [RR1.88 (95%CI: 0.69-5.12);P = 0.22;I2 = 0%] and high-dose [RR 1.27 (95% CI: 0.45 - 3.59); P = 0.68; I2 = 0%] rivoglitazone was comparable to placebo. This meta-analysis highlights the good glycaemic efficacy and safety of both standard and high-dose rivoglitazone, and appears to be better than lobeglitazone in T2DM.
