Abstract
The G protein-coupled estrogen receptor (GPER, GPR30) represents a promising target for the treatment of estrogen receptor α and β negative breast cancers. Previously reported agonists of GPER have shown that activation of GPER inhibits breast cancer cell proliferation. We report herein a new GPER agonist scaffold based upon in silico pharmacophore screening. Three of these compounds were found to increase cAMP at similar levels as the known GPER-selective agonist G-1. Compound 5 was found to be selective for GPER (over estrogen receptor α and β) and inhibit breast cancer cell proliferation at levels consistent with G-1. Docking studies go on to suggest that both 5 and G-1 bind within the same binding pocket in GPER and point to possible key residues that are important in GPER activation.
