Irosustat (Cat No.: I007362) is a potent and orally active steroid sulfatase inhibitor. It functions by irreversibly inhibiting the activity of steroid sulfatase, an enzyme involved in the metabolism of steroid hormones, including estrogens. By inhibiting this enzyme, Irosustat can reduce the levels of active estrogens in the body. This property makes it of interest in the field of hormone-related conditions, particularly in hormone-dependent cancers like breast and prostate cancer.
