17β-Hydroxysteroid dehydrogenase type 1 (17β-HSD1) represents a promising therapeutic target for breast cancer treatment. To reduce the undesirable estrogenic activity of potent 17β-HSD1 inhibitor 16β-(m-carbamoylbenzyl)estradiol (1) (IC(50) = 27 nM), a series of analogues with a small functionalized side chain at position 3 were synthesized and tested. The 3-(2-bromoethyl)-16β-(m-carbamoylbenz...

17-β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) is an important enzyme involved in the final steps of androgen synthesis and is required for the development of normal male external genitalia. 46,XY individuals with deficiency of this enzyme present a wide clinical spectrum from a female appearance of the external genitalia through ambiguous genitalia to a predominantly male genitalia with m...

Sex steroid hormones such as estrogens and androgens are involved in the development and differentiation of the breast tissue. The activity and concentration of sex steroids is determined by the availability from the circulation, and on local conversion. This conversion is primarily mediated by aromatase, steroid sulfatase, and 17β-hydroxysteroid dehydrogenases. In postmenopausal women, this is...

Androstenone is one of the main compounds responsible for boar taint, and 3β-hydroxysteroid dehydrogenase (3βHSD) might be involved in its metabolism. In this study, the gene expression of 3βHSD and 17β-hydroxysteroid dehydrogenase (17βHSD) were determined by real-time PCR analysis and related to the concentrations of androstenone, testosterone, and estrone sulphate (E1S). The experiments were ...
