Development of 3-substituted-androsterone derivatives as potent inhibitors of 17β-hydroxysteroid dehydrogenase type 3
摘要:
17Beta-hydroxysteroid dehydrogenase type 3 (17 beta-HSD3) is a steroidogenic enzyme that catalyzes the transformation of 4-androstene-3,17-dione (Delta(4)-dione) into androgen testosterone (T). To provide effective inhibitors of androgen biosynthesis, we synthesized two different series (amines and carbamates) of 3 beta-substituted-androsterone derivatives and we tested their inhibitory activity on 17 beta-HSD3. From the results of our structure-activity relationship study, we identified a series of compounds producing a strong inhibition of 17 beta-HSD3 overexpressed in HEK-293 cells (homogenized cells). The most active compound when tested in intact HEK-293 transfected cells, namely (3 alpha,5 alpha)-3-{[trans-2,5-dimethyl-4-{[2-(trifluoromethyl)phenyl] sulfonyl}piperazin-1-yl]methyl}-3-hydroxyandrostan-17-one (15b), shows an IC50 value of 6 nM, this compound is thus eight times more active than our reference compound D-5-2 (IC50 = 51 nM). This new improved inhibitor did not stimulate the proliferation of androgen-sensitive Shionogi cells, suggesting a non-androgenic profile. Compound 15b is thus a good candidate for further in vivo studies on rodents. (C) 2011 Elsevier Ltd. All rights reserved.

The present application discloses 17β hydroxy steroid dehydrogenase (17β HSD) type 1, 3, 10 inhibitors and use thereof (alone and in combination) in the treatment of cancer and other afflictions. 17β HSDl inhibitors include estradiol derivatives with a nieta-carbamoylbenzyl substituent at C 16. 17β HSD3/HSD10 inhibitors include androsterone derivatives substituted at the C3 position with a sulfonamide piperazine. Also disclosed are compounds that are inhibitors of both 17β HSDl and 17β HSD3 that have a spiro-morpholine substituent at C20.
