Perhydroquinolylbenzamides as novel inhibitors of 11beta-hydroxysteroid dehydrogenase type 1.

摘要

High-throughput screening identified 5 as a weak inhibitor of 11beta-HSD1. Optimization of the structure led to a series of perhydroquinolylbenzamides, some with low nanomolar inhibitory potency. A tertiary benzamide is required for biological activity and substitution of the terminal benzamide with either electron-donating or -withdrawing groups is tolerated. The majority of the compounds show selectivity of >20 to >700-fold over 11beta-HSD2. Analogues which showed >50% inhibition of 11beta-HSD1 at 1 muM in an cellular assay were screened in an ADX mouse model. A maximal response of >70% reduction of liver corticosterone levels was observed for three compounds; 9m, 25 and 49.
