Cetrorelix Acetate (SB-075 acetate) is a synthetic gonadotropin-releasing hormone (GnRH) antagonist (IC50 = 1.21nM) [1]. Cetrorelix Acetate inhibits the GnRH signaling pathway, thereby reducing the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) [2-3]. Cetrorelix Acetate is used to treat premature ovulation [4].
In epithelial cells, treatment with Cetrorelix Acetate (1-20ng/mL; 10d) significantly reduced cell growth rate [5]. In HTOA cells, Cetrorelix Acetate (10nM-10μM; 24-96h) treatment showed a dose-dependent anti-proliferative effect on cells [6].
In C57BL/6J mice, Cetrorelix Acetate (5µg/kg; ip; 7d) improves superovulation efficacy in aged mice without compromising oocyte quality [7]. In CFLP male mice, Cetrorelix Acetate (2µg; 2µL; intraventricular injection; single injection) attenuates the effects of beta-amyloid 25-35 [8].
