5-Chloroindole: a potent allosteric modulator of the 5-HT3 receptor: Allosteric modulation of the 5-HT3receptor

Research output: Contribution to journalArticlepeer-review



The 5-HT3 receptor is a ligand-gated ion channel that is modulated allosterically by various compounds including colchicine, alcohols and volatile anaesthetics. However the positive allosteric modulators (PAMs) identified to date have low affinity, which hinders investigation because of non-selective effects at pharmacologically active concentrations. The present study identifies 5-chloroindole (Cl-indole) as a potent PAM of the 5-HT3 receptor.
