Synthesis and hypoglycemic activity of new nicotinonitrile-furan molecular hybrids

Abstract

New hybrid molecules bearing 4-(2-furyl)-1,4-dihydronicotinonitrile and 4-(2-furyl)-1,4,5,6-tetrahydronico- tinonitrile fragments were prepared starting from cyanothioacetamide and furfural. The hypoglycemic activity in dexamethasone-induced diabetes mellitus was investigated in vivo in senile rats. Some compounds revealed hypoglycemic effects superior to that of the reference drug (metformin).
