A series of ten N-(3-(1H-tetrazole-5-yl)phenyl)acetamide derivatives (NM-07 to NM-16) designed from a lead molecule identified previously in our laboratory were synthesized and evaluated for protein tyrosine phosphatase 1B (PTP1B) inhibitory activity. Among the synthesized molecules, NM-14, a 5-Cl substituted benzothiazole analogue elicited significant PTP1B inhibition with an IC50 of 1.88 mu M against reference standard suramin (IC50 >= 10 mu M). Furthermore, this molecule also showed good in vivo antidiabetic activity which was comparable to that of standard antidiabetic drugs metformin and glimepiride. Overall, the results of the study clearly reveal that the reported tetrazole derivatives especially NM-14 are valuable prototypes for the development of novel non-carboxylic inhibitors of PTP1B with antidiabetic potential.
