Pricing Availability Delivery Time Qty
Cat.No. 3536 - Cetrorelix Acetate | Ac-D-2-Nal-D-(4-Cl-Phe)-D-(3-Pyridyl-Ala)-Ser-Tyr-D-Cit-Leu-Arg-Pro-D-Ala-NH2.CH3CO2H | CAS No. 145672-81-7
Description: Potent GnRH receptor antagonist

Biological Activity

Potent gonadotropin-releasing hormone (GnRH) receptor antagonist (KD = 0.202 nM, IC50 = 1.21 nM). Suppresses production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland, which inhibits ovulation. Exhibits antiproliferative effects and displays efficacy against hormone-sensitive cancers in vivo. Also exhibits anxiolytic and antidepressant activity in vivo.
