CAS 41727-47-3: Methyl 3,5-dibromo-4-hydroxybenzoate

Methyl 3,5-dibromo-4-hydroxybenzoate

Estrogens are steroid hormones that regulate a variety of physiological processes including reproduction, bone metabolism, and the development of certain cancers. Estrogens are synthesized from C-19 and C-20 steroids such as progesterone and testosterone. The conversion of these precursors to estrogens is catalyzed by the cytochrome P450 enzyme 17 beta-hydroxysteroid dehydrogenase (17βHSD). Methyl 3,5-dibromo-4-hydroxybenzoate is a selective inhibitor for 17βHSD. It binds to the active site of 17βHSD, preventing it from catalyzing the conversion of C-19 or C-20 steroids to estrogens. This inhibition has been shown to lead to an increase in circulating levels of sex hormone binding globulin (SHBG) and consequently a decrease in free estrogen levels.

Methyl 3,5-dibromo-4-hydroxybenzoate is used to produce 4-hydroxy-3,5-di-pyridin-2-yl-benzoic acid methyl ester at temperature of 90-100°C.
