Description

GnRH-R antagonist 1 (compound 21a) is an orally safe and membrane-permeable GnRH-R antagonist with high binding affinity (IC50=0.57 nM) and potent in vitro antagonistic activity (IC50=2.18 nM). GnRH-R antagonist 1 can be used in studies of advanced prostate cancer and premature LH peaks preventing[1].

In Vitro

GnRH-R antagonist 1 has a 140-fold higher cell permeability than Relugolix and exhibits favorable stability in human and mouse microsome[1].

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.
