Number of heterocyclic compounds has been exploited to develop pharmaceutically important molecules, out of which biheterocyclic coumarins are clinically used potential drug candidates showing oral hypoglycemic and antidiabetic activities. A new series of 3-[5'-methyl-2'-aryl-3'-(thiazol-2ʺ-yl amino)thiazolidin-4'-one]coumarin derivatives were designed and synthesized. The title compounds were synthesized from starting material 3- acetyl coumarin. All the synthesized compounds were characterized and screened for hypoglycemic activity. Some of the compounds exhibited promising activity.
