Synthesis, Hypoglycaemic, Hypolipidemic and PPAR gamma Agonist Activities of 5-(2-Alkyl/aryl-6-Arylimidazo[2,1-b][1,3,4]thiadiazol-5-yl) methylene-1,3-Thiazolidinediones

Abstract

A novel series of 5-(2-alkyl/aryl-6-arylimidazo[2,1-b][1,3,4]thiadiazol-5-yl)methylene-1,3-thiazolidinediones were synthesized as possible PPAR agonists. The structures of these target molecules were established by spectral and analytical data. All the newly synthesized compounds were screened for their in vivo hypoglycaemic and hypolipidemic activity in male Wistar rats. Further, compounds with good activity were screened for PPAR agonist activity. Among the screened compounds, 5-{[2-Cyclohexyl-6-(4-methoxyphenyl)imidazo[2,1-b] [1,3,4]thiadiazol-5-yl]methylene}-1,3-thiazolidine-2,4-dione (3i) exhibits promising hypoglycaemic and hypolipidemic activity via potential PPAR agonist activity.
