Estrogens are the major female sex steroid hormones, estradiol (E2) being the most potent form in humans. Disturbing the balance between E2 and its weakly active oxidized form estrone (E1) leads to diverse types of estrogen-dependent diseases such as endometriosis or osteoporosis. 17\u03b2-Hydroxysteroid dehydrogenase type 1 (17\u03b2-HSD1) catalyzes the biosynthesis of E2 by reduction of E1 while the type 2 enzyme catalyzes the reverse reaction. Thus, 17\u03b2-HSD1 and 17\u03b2-HSD2 are attractive targets for treatment of estrogen-dependent diseases. Recently, we reported the first proof-of-principle study of a 17\u03b2-HSD2 inhibitor in a bone fracture mouse model, using s.c. administration. In the present study, our aim was to improve the in vitro ADME profile of the most potent 17\u03b2-HSD1 and 17\u03b2-HSD2 inhibitors described so far. The optimized compounds show strong and selective inhibition of both the human enzymes and their murine orthologs. In addition, they display good metabolic stability in human liver microsomes (S9 fraction), low in vitro cytotoxicity as well as better aqueous solubility and physicochem. properties compared to the lead compounds These achievements make the compounds eligible for testing in preclin. in vivo animal model studies on the effects of inhibition of 17\u03b2-HSD1 and 17\u03b2-HSD2.<\/p>\n<p>269410-08-4, 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole, also known as 4-Pyrazoleboronic acid pinacol ester , is a useful research compound.
