Abstract

Traditional approaches to discovery of selective estrogen receptor modulators (SERMs) have relied on ER binding and cell-based estrogen response element-driven assays to identify compounds that are osteoprotective but nonproliferative in breast and uterine tissues. To discover new classes of potential SERMs, we have employed a cell-free microsphere-based binding assay to rapidly characterize ERalpha interactions with conformation-sensing cofactor or phage display peptides. Peptide profiles of constrained triarenes were compared to known proliferative and nonproliferative ER ligands to discover potent quinoline-based ligands with minimal Ishikawa cell stimulation.
