boron-modified GW7604 derivative (GLL398, 9), a SERD candidate, in which a boronic acid functional group replaces the phenolic hydroxyl group of GW7604. Compound9 strongly binds to ERα in a fluorescence resonance energy transfer binding assay (IC50 = 1.14 nM) and potently degrades ERα in MCF-7 breast cancer cells (IC50 = 0.21 μM). Most importantly, the introduction of the boronic acid group confers superior oral
