| + | To increase the chemical diversity of bioactive molecules by incorporating unusual elements, we have examined the replacement of a C=C double bond with the isoelectronic, isostructural B-N bond in the context of nonsteroidal estrogen receptor (ER) ligands. While the B-N bond was hydrolytically labile in the unhindered cyclofenil system, the more hindered anilino dimesitylboranes, analogs of triarylethylene estrogens, were easily prepared, hydrolytically stable, and demonstrated substantial affinity for ERs. X-ray analysis of one ERalpha-ligand complex revealed steric clashes with the para methyl groups distorting the receptor; removal of these groups resulted in an increase in affinity, potency, and transcriptional efficacy. These studies define the structural determinants of stability and cellular bioactivity of a B-N for C=C substitution in nonsteroidal estrogens and provide a framework for further exploration of "elemental isomerism" for diversification of drug-like molecules. | ||
