The selective ER\u03b2 agonist AC-131 has shown efficacy in animal models of Parkinson's disease and neuropathic pain. With the use of AC-131 as template, herein we report the discovery, synthesis, and structure-activity relationship (SAR) study of a new class of dihydrobenzofurans as potent and selective ER\u03b2 agonists. The SAR was established by enantioselective synthesis, molecular modeling, and whole-cell-based functional assays. The most potent diastereomer, cis-10-SR, was shown to have an EC50 value of <1 nM, potency 100-fold higher than that of AC-131. Even more interestingly, compound trans-10-SS exhibited 1000-fold ER\u03b2/ER\u03b1 selectivity while still maintaining good potency (\u223c10 nM). In addition, trans-10-SS showed only partial agonist activity (30-60 % Eff.) toward ER\u03b1 at 10 \u03bcM. This unprecedented selectivity could be rationalized by molecular modeling. Compound trans-10-SS appears to be the first molecule to take advantage of both conservative amino acid differences found in the \u03b1- and \u03b2-faces of the binding cavities of ER\u03b1 and ER\u03b2.", "doi": "10.1002/cmdc.201300175", "pmid": "23784708", "labels": {"Chemical Biology Consortium Sweden": "Collaborative"}, "xrefs": [], "notes": [], "created": "2017-10-20T14:59:35.171Z", "modified": "2025-10-17T13:04:30.324Z"}
