Chemical Name: (3aS*,4R*,9bR*)-4-(6-Bromo-1,3-benzodioxol-5-yl)-3a,4,5,9b-3H-cyclopenta[c]quinoline

Biological Activity

High 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.

Technical Data

Soluble to 50 mM in DMSO
>99 %
Store at -20°C
