Discovery of novel PTP1B inhibitors via pharmacophore-oriented scaffold hopping from Ertiprotafib
摘要:
An integrated molecular design strategy combining pharmacophore recognition and scaffold hopping was exploited to discover novel PTP1B inhibitors based on the known PTP1B inhibitor Ertiprotafib. A composite pharmacophore model was proposed from the interaction mode of Ertiprotafib, and 21 diverse molecules from five distinct structural classes were designed and synthesized accordingly. New compounds with considerable inhibition against PTP1B were identified from each series, and the most active compound 3a showed IC50 value of 1.3 mu mol L-1 against human recombinant PTP1B. Docking study indicated that the new inhibitors assumed binding modes similar to that of Ertiprotafib. (C) 2013 Elsevier Ltd. All rights reserved.

The microsomal prostaglandin E-2 synthase 1 (mPGES-1) became a desirable target in recent years for the research of new anti-inflammatory drugs. Even though many potent inhibitors of human mPGES-1, tested in vitro assay systems, have been synthesized, they all failed in preclinical trials in rodent models of inflammation, due to the lack of activity on rodent enzyme. Within this work we want to present a new class of mPGES-1 inhibitors derived from a benzenesulfonamide scaffold with inhibitory potency on human and murine mPGES-1. Starting point with an IC50 of 13.8 mu M on human mPGES-1 was compound 1 (4-benzyl[(4-methoxyphenyl) methyl] sulfamoyl} benzoic acid; FR4), which was discovered by a virtual screening approach. Optimization during a structure-activity relationship (SAR) process leads to compound 28 (4-[(cyclohexylmethyl)[(4-phenylphenyl) methyl] sulfamoyl] benzoic acid) with an improved IC50 of 0.8 mu M on human mPGES-1. For the most promising compounds a broad pharmacological characterization has been carried out to estimate their anti-inflammatory potential. (C) 2013 Elsevier Ltd. All rights reserved.
