BioAssay: AID 644974

Antagonist activity at glucocorticoid receptor in human A549 cells assessed as inhibition of dexamethasone-induced transcription at GRE after 24 hrs by luciferase reporter gene assay

Early studies led to the identification of 11beta-aryl-4',5'-dihydrospiro[estra-4,9-diene-17beta,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 17beta-formamido more ..

Title: Synthesis and antihormonal properties of novel 11beta-benzoxazole-substituted steroids.

Abstract: Early studies led to the identification of 11beta-aryl-4',5'-dihydrospiro[estra-4,9-diene-17beta,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 17beta-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.
