DCW234

DCW234, also known as butyl 4-(butyryloxy)benzoate, is a synthetic nonsteroidal estrogen and a selective agonist 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]
