Structural Optimization of 2,5-Thiophene Amides as Highly Potent and Selective 17β-Hydroxysteroid Dehydrogenase Type 2 Inhibitors for the Treatment of Osteoporosis
摘要:
Inhibition of 17 beta-HSD2 is an attractive mechanism for the treatment of osteoporosis. We report here the optimization of human 17 beta-HSD2 inhibitors in the 2,5-thiophene amide class by varying the size of the linker (n equals 0 and 2) between the amide moiety and the phenyl group. While none of the phenethylamides (n = 2) were active, most of the anilides (n = 0) turned out to moderately or strongly inhibit 17 beta-HSD2. The four most active compounds showed an ICso of around 60 nM and a very good selectivity toward 17 beta-HSD1, 17 beta-HSD4, 17 beta-HSD5, 11 beta-HSD1, 11 beta-HSD2 and the estrogen receptors alpha and beta. The investigated compounds inhibited monkey 17 beta-HSD2 moderately, and one of them showed good inhibitory activity on mouse 17 beta-HSD2. SAR studies allowed a first characterization of the human 17 beta-HSD2 active site, which is predicted to be considerably larger than that of 17 beta-HSD1.
