HSD-016（Cat No.:I028900）is an investigational compound that acts as a selective inhibitor of 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1), an enzyme involved in the conversion of estrone to estradiol, a potent estrogen. By inhibiting this enzyme, HSD-016 aims to lower estrogen levels, which could be beneficial in the treatment of estrogen-dependent conditions such as hormone receptor-positive breast cancer. Additionally, it may have potential applications in other diseases related to estrogen overproduction. HSD-016 is being studied for its ability to selectively target this pathway, offering a potential therapeutic option for managing estrogen-related disorders.
