Cat. No. 3678
Chemical Name: (3aS*,4R*,9bR*)-4-(6-Bromo-1,3-benz
Biological ActivityHigh affinity and selective GPER receptor antagonist (Ki = 20 nM) that displays no affinity for ERα and ERβ at concentrations up to 10 μM. Inhibits agonist-induced calcium mobilization in vitro (EC50 of ~185 nM) and antagonizes the antidepressive and renoprotective effects of estrogen in vivo.
