DCW234, also known as butyl 4-(butyryloxy)benzoate, is a syntheticnonsteroidalestrogen and a selectiveagonist of the ERβ.[1][2][3] It shows modest selectivity in terms of affinity and transactivation for the ERβ over the ERα.[1] Its affinity for the ERβ was 3.43 μM and for the ERα was 22.5 μM, while it activated the ERβ and ERα with EC50 values of 1.71–2.5 μM and 19.8–22.5 μM, respectively.[1] As such, its binding selectivity for the ERβ over the ERα was 7-fold and its functional selectivity for the ERβ over the ERα was between 10- and 13-fold.[1]
