Biological Activity

Potent and selective GPER agonist (Ki = 11 nM, EC50 = 2 nM); displays no activity at ERα and ERβ at concentrations up to 10 μM. Increases cytosolic Ca2+ and inhibits migration of SKBr3 cells and MCF-7 cells in response to chemoattractants (IC50 values are 0.7 and 1.6 nM respectively) in vitro. Blocks MCF-1 cell cycle progression at the G1 phase. Displays therapeutic effects in the mouse EAE model of multiple sclerosis.
