      Currents were elicited by 10 µM 5-HT, delivered every 3 minutes. 3-AQC (#A-205) was applied 30 seconds before stimulation at 10 and 100 µM, as indicated, and inhibited the 5-HT induced current in a dose-dependent and reversible manner.

    Scientific background

    Serotonin (5-hydroxytryptamine, 5-HT) is a monoamine neurotransmitter synthesized from the amino acid tryptophan by the enzyme tryptophan-decarboxylase. The 5-HT3 channel is a ligand gated ion channel receptor of the cys-loop channel family. It is a pentamer with five subunits surrounding a central channel1.

    3-AQC is a potent and selective antagonist of the 5-HT3A channel. 3-AQC is a derivative of Piperazinyquinoxaline synthetically designed to be 100 times more potent in blocking Serotonin receptors than Tropisetron.
