Design, synthesis and biological evaluation of thiazole- and indole-based derivatives for the treatment of type II diabetes

Present studies have shown that the lipid carrier has a significant role in several aspects of metabolic syndrome in A-FABP/ap2-deficient mice, including type 2 diabetes and atherosclerosis. 38 Thiazole- and indole-based derivatives were synthesized and investigated for their inhibitory effects on the production of LPS-stimulated TNF-alpha. Among them, 12b exhibited an excellent inhibitory efficiency compared to BMS309403 (95% vs. 85%) at the concentration of 10 mu M and a binding affinity for ap2 with the apparent K-i values 33 nM. Oral administration of 12b at a dosage of 50 mg/kg effectively reduced the levels of plasma blood glucose, triglycerides, insulin, total cholesterol and alanine aminotransferase in high-fat/diet-induced obesity model. The results highlighted that 12b was a potent anti-diabetic agent. (C) 2012 Elsevier Masson SAS. All rights reserved.
