Cetrorelix diacetate (SB-075 diacetate) is a potent gonadotropin-releasing hormone (GnRH) receptor antagonist with an IC50 of 1.21 nM[1].

IC50 & Target

IC50: 1.21 nM GnRH[1].

In Vitro

Cetrorelix diacetate inhibits growth of ES-2 cell line at 1000 ng/ml. Cetrorelix diacetate has comparable antiproliferative effects as GnRH-I agonists indicating that the dichotomy of GnRH-I agonists and antagonists might not apply to the GnRH-I system in cancer cells[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
