Description

General description

A cell-permeable benzylidine-thioxothiazolidinone compound that blocks the steroidogenesis of testosterone by directly inhibiting 17β-HSD3- (17β-hydroxysteroid dehydrogenase type 3) catalyzed, NADPH-dependent, reduction of Δ⁴-dione C17 ketone in a Δ⁴-dione- (4-androstene-3,17-dione) competitive, highly potent (IC₅₀ = 0.6, 6.0, and 40 nM, respectively, against momoset, human, and mouse 17β-HSD3 activity in testes homogenate), and selective manner, displaying no activity against 17β-HSD1 and 17β-HSD2 activity. Poor pharmacokinetic properties limit its use to culture treatments and cell-free assays only.

A cell-permeable benzylidine-thioxothiazolidinone compound that blocks the steroidogenesis of the potent androgen testosterone by directly inhibiting 17β-HSD3- (17β-hydroxysteroid dehydrogenase type 3) catalyzed, NADPH-dependent, reduction of Δ⁴-dione C17 ketone in a Δ⁴-dione- (4-androstene-3,17-dione) competitive, highly potent (IC₅₀ = 0.6, 6.0, and 40 nM, respectively, against momoset, human, and mouse 17β-HSD3 activity in testes homogenate; IC₅₀ = 14 nM using 17β HSD3-transfected HeLa cells), and selective manner, displaying no activity against 17β-HSD1 and 17β-HSD2 activity in HeLa transfectants or AR- (andogen receptor), ERα- (estrogen receptor α), and GR- (glucocorticoid receptor) dependent transcription activities. Low aqueous solubility, lack of oral availability, and other poor pharmacokinetic properties limit its use to culture treatments and cell-free assays only.
