New nonsteroidal human androgen receptor (hAR) agonists were developed from an hAR antagonist pharmacophore, 2(1H)-piperidino[3,2-g]quinolinone. (+/-)-trans-7,8-Diethyl-4-trifluoromethyl-2(H)-piperidino-[3,2-g]quinoli none was synthesized and demonstrated potent hAR agonist activity (EC50=3 nM) in the cell-based cotransfection assay and high binding affinity (Ki=16 nM) in the
