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

Dopamine neurons mediate the association of conditioned stimuli (CS) with reward (unconditioned stimuli, US) by signaling the discrepancy between predicted and actual reward during the US. Some theoretical models suggest that learning is also influenced by the salience or associability

Many bacteria, including Vibrio spp., regulate virulence gene expression in a cell-density dependent way through a communication process termed quorum sensing (QS). Hence, interfering with QS could be a valuable novel antipathogenic strategy. Cinnamaldehyde has previously been shown to inhibit
