Graphical Abstract:


Protein tyrosine phosphatase 1B (PTP1B) is a well known drug target for the treatment of type 2 diabetes mellitus (T2DM). Diverse inhibitors have been reported in literature that inhibit PTP1B. We have reported 2-substituted benzoxazole class of In PTP1B inhibitors earlier. Present work describes 2-substituted benzothiazole compounds as PTP1B inhibitor as an extension of our previous study. Compound 23c, a disubstituted para-Bromobenzyl sulfonamide compound, exhibited moderate biochemical potency (Ki) of 1.4 µM. SAR on synthesized compounds was explained using molecular modeling study.

Keywords: Benzothiazoles, Oxamic acids, PTP1B, Type 2 Diabetes, pTyr mimetics, Disubstituted sulfonamides.
