In this work , we used a combined strategy to find new antagonist structures distinct from the 4 - cyano - 3 - ( trifluoromethyl ) phenyl group to avoid cross - resistance for these compounds and to find structures without agonist activity on mutant ARs ( AR W741C and AR T877A ) .
 Chemical: 4 - cyano - 3 - ( trifluoromethyl ) phenyl
