G36 is a cell-permeable non-steroidal antagonist of GPER. G36 inhibits activation by either 17β-estradiol or the GPER-selective agonist G-1 (IC50 = 112 and 165 nM, respectively).

G36 blocks the activation of PI3K or calcium mobilization triggered by estrogen through GPER and it suppresses ERK activation by estrogen or G-1 but not by EGF. G-36 can be used in combination with GPER-selective agonists, like G-1, to distinguish the roles of GPER from those of ERα and ERβ in complex biological systems.
