Relugolix-D6 is a deuterated compound of Relugolix. Relugolix (
T3630) has a CAS number of 737789-87-6. Relugolix (
T3630) is an orally available, non-
peptide gonadotropin-
releasing hormone (GnRH or luteinizing
hormone-
releasing hormone (LHRH)) antagonist, with potential antineoplastic activity. Relugolix (
T3630) competitively binds to and blocks the GnRH receptor in the anterior pituitary gland, which both prevents GnRH binding to the GnRH receptor and inhibits the secretion and release of both luteinizing
hormone (LH) and follicle stimulating
hormone (FSH). In males, the inhibition of LH secretion prevents the release of testosterone from Leydig cells in the testes. Since testosterone is required to sustain prostate
growth, reducing testosterone levels may inhibit
hormone-dependent prostate cancer cell proliferation.
