Abstract

A series of 6-nitro-3-(m-tolylamino) benzo[d]isothiazole 1,1-dioxide analogues were synthesized and evaluated for their inhibition activity against 5-lipoxygenase (5-LOX) and microsomal prostaglandin E2 synthase (mPGES-1). These compounds can inhibit both enzymes with IC50 values ranging from 0.15 to 23.6μM. One of the most potential compounds, 3g, inhibits 5-LOX and mPGES-1 with IC50 values of 0.6μM, 2.1μM, respectively.

Keywords: 5-Lipoxygenase; Benzo[d]isothiazole 1,1-dioxide; Dual functional inhibitor; Microsomal prostaglandin E(2) synthase.
