GPR30 is a transmembrane G protein-coupled receptor (GPCR) localized to endoplasmic reticulum (ER) that binds estradiol with high affinity, activating multiple intracellular signaling pathways. G-1 is a nonsteroidal, high-affinity, selective agonist of GPR30 that binds with a K_i value of 11 nM. Competitive binding studies in estrogen receptor α- (ERα-) and ERβ-expressing cells yielded K_i values for estradiol of 0.30 and 0.38 nM, respectively, with no substantial binding of G-1 at 1 μM. The discovery of G-1, a compound that does not bind classical ERs, should facilitate further physiological experiments to define the role of GPR30 in vivo.

G-1 is a potent and selective G protein-coupled estrogen receptor (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.

ChEBI: 1-[4-(6-bromo-1,3-benzodioxol-5-yl)-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinolin-8-yl]ethanone is a member of quinolines.
