WAY-166818 is a synthetic, nonsteroidal estrogen related to WAY-200070 which is used in scientific research.[1][2] It acts as a highly selective full agonist of the ERβ, with 57- and 164-fold selectivity for the ERβ over the ERα in the rat and mouse, respectively.[1][2] At the human ERβ and ERα, WAY-166818 has IC50 values of 29 nM and 1227 nM (25-fold difference), respectively.[1] The compound has been verified to cross the blood-brain-barrier in rodents.[1][2]
