α-Glucosidase Inhibitory Activity of 4-Aryl-N-(2,4-Thiazolidinedione-5-Acetyl)-1,3-Thiazol-2-Amines.

ABSTRACT

A series of N-(4-aryl-1,3-thiazol-2-yl)-2-(2,4-dioxo-1,3-thiazolidin-5-yl)acetamides 3a-k and N- (1,3-benzothiazol-2-yl)-2-(2,4-dioxo-1,3-thiazolidin-5-yl)acetamides 3l-n are synthesized and evaluated for their α-glucosidase inhibitory activity. N-[4-(m-Chlorophenyl)-1,3-thiazol-2yl]-2-(2,4-dioxo-1,3-thiazolidin-5- yl)acetamide (3g) and N-[4-(o-fluorophenyl)-1,3-thiazol-2-yl]-2-(2,4-dioxo-1,3-thiazolidin-5-yl)acetamide (3j) have shown very good inhibition. The remaining compounds have exhibited moderate to good activity ranging from 37- 63 % of α-glucosidase enzyme inhibition.
