Abstract

A new series of phosphorus-containing 11beta-aryl-substituted Steroids have been synthesized in an eight-step sequence involving a palladium-catalyzed coupling reaction to introduce a phosphorus group onto the aromatic ring. The compounds were evaluated for Progesterone Receptor (PR) antagonist activity in a T47D cell-based assay and for Glucocorticoid Receptor (GR) antagonist activity in an A549 cell-based assay. The structure-activity relationships of these compounds are discussed. Selected compounds were tested in vivo in a rat complement C3 assay.
