Cetrorelix acetate (SB-75)

InvivoChem Cat #:V4630CAS #:145672-81-7Purity >=98%

Description: Cetrorelix mono-acetate (SB-75) is a novel, potent and synthetic gonadotropin-releasing hormone (GnRH) receptor antagonist with an IC50 of 1.21 nM. Cetrorelix acetate is a decapeptide with the potential to be used in infertility treatment. The expression of GnRH (GnRH-I, LHRH) and its receptor as a part of an autocrine regulatory system of cell proliferation has been demonstrated in a number of human malignant tumors, including cancers of the ovary. The proliferation of human ovarian cancer cell lines is time- and dose-dependently reduced by GnRH and its superagonistic analogs.
