We have developed a new series of Progesterone Receptor modulators based upon the 4-aryl-phenylsulfonamide. Initial work in the series afforded potent compounds with good properties, however an advanced intermediate proved to be genotoxic in a non-GLP Ames assay following metabolic activation. We subsequently solved this problem and identified advanced leads which demonstrated oral efficacy in rhesus monkey pharmacodynamic and kinetics models.
