Estrogen receptor ligands. II. Discovery of benzoxathiins as potent, selective estrogen receptor alpha modulators.
S.Kim, J.Y.Wu, E.T.Birzin, K.Frisch, W.Chan, L.Y.Pai, Y.T.Yang, R.T.Mosley, P.M.Fitzgerald, N.Sharma, J.Dahllund, A.G.Thorsell, F.DiNinno, S.P.Rohrer, J.M.Schaeffer, M.L.Hammond.
The discovery and synthesis of dihydrobenzoxathiins as potent, ERalpha subtype selective ligands are described. The most active analogue, 4-D, was found to be 50-fold selective in a competitive binding assay and 100-fold selective in a transactivation assay in HEK-293 cells. The alpha selectivity was postulated to lie in the interaction of the sulfur atom of the benzoxathiin ring with the two discriminating residues in the binding pocket of the receptor isoforms.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
