  Potent and Selective Steroidal Inhibitors of 17β-Hydroxysteroid Dehydrogenase Type 7, an Enzyme That Catalyzes the Reduction of the Key Hormones Estrone and Dihydrotestosterone

  摘要：

  17 beta-Hydroxysteroid dehydrogenase type 7 (17 beta-HSD7) catalyzes the reduction of estrone (E-1) into estradiol (E-2) and of dihydrotestosterone (DHT) into 5 alpha-androstane-3 beta,17 beta-diol (3 beta-diol), therefore modulating the level of mitogenic estrogens and androgens in humans. By classical and parallel chemistry, we generated several 4-methyl-4-aza-5 alpha-androstane derivatives differing in their C-17 substituent: 17 beta-formamide, 17 beta-benzamide, and 17 beta-tertiary amine. Best candidates in each category had demonstrated good inhibitory potency toward the conversion of E-1 into E-2 (IC50 = 189-451 nM) and also toward the conversion of DHT into 3 beta-diol (69-91% at 3 mu M). Inhibition assays with 17 beta-HSD1, 17 beta-HSD5, 5 alpha-reductase (5 alpha-R) 1 and 5 alpha-R2 revealed that 17 beta-HSD7 inhibitors with a 4-methyl-4-aza nucleus were also able to inhibit 5 alpha-Rs but not the other enzymes tested. Two 4-aza-5 alpha-androstane inhibitors were, however, selective and still showed good inhibition of 17 beta-HSD7. First selective and efficient inhibitors of 17 beta-HSD7 are now available for additional mechanistic and therapeutic studies.
