Biological Activity for Ondansetron hydrochloride
Ondansetron hydrochloride is a selective 5-HT3 receptor antagonist (Ki = 6.16 nM). Also an inhibitor of human multidrug and toxin extrusion (MATE) transporter 1 (IC50 = <10-160 nM). Ondansetron blocks 5-HT-evoked transient inward currents (IC50 = 0.1 nM) in human recombinant h5-HT3A receptors. In an animal model of Parkinson's disease, Ondansetron reduces both the severity of dyskinesia and psychosis-like behaviors. Antiemetic; prevents emesis induced by cytotoxic drugs and radiation.
