  Synthesis and antihormonal properties of novel 11β-benzoxazole-substituted steroids

  摘要：

  Early studies led to the identification of 11 beta-aryl-4',5'-dihydrospiro[estra-4,9-diene-17 beta,4'-oxazole] analogs with potent and more selective antiprogestational activity compared to antiglucocorticoid activity than mifepristone. In the present study, we replaced the 4'-dimethylaminophenyl group of mifepristone with the benzoxazol group to give 5a-d. We also prepared the 17 beta-formamido analogs 6a,b using a new synthetic strategy via the intermediate epoxide 21. These compounds were evaluated for their antagonist hormonal properties using the T47D cell-based alkaline phosphatase assay and the A549 cell-based functional assay. Compound 5c showed potent antagonist activity at GR with better selectivity for GR versus PR than mifepristone and is a promising lead for further development. (C) 2011 Elsevier Ltd.
