High-throughput screening of a small-molecule compound library resulted in the identification of a series of arylsulfonylpiperazines that are potent and selective inhibitors of human 11β-Hydroxysteroid Dehydrogenase Type 1 (11β-HSD1). Optimization of the initial lead resulted in the discovery of compound (R)-45 (11β-HSD1 IC50 = 3 nM).

A series of 4-(2-pyridyl)piperazine-1-benzimidazole analogues based on compound 1 was synthesized and evaluated for TRPV1 antagonist activity in capsaicin-induced (CAP) and pH 5.5-induced (pH) FLIPR assays in a human TRPV1-expressing HEK293 cell line. Potent TRPV1 antagonists were identified through SAR studies. From these studies, several antagonists were found, with IC50 values ranging from 32 nM to ~5000 nM. Among these, 11 [IC50 = 90 nM (CAP) and 104 nM (pH)] was further evaluated and found to be orally available in rats (F% = 19.7).
