In vitro study | Tropisetron is a high affinity ligand for the α7 choline receptor and 5HT3R. Tropisetron has very low affinity for the other nicotine subtypes tested. Tropisetron is a potent and selective serotonin 3(5-hydroxytryptamine3;5-HT 3) receptor antagonist with antiemetic effects, it may be mediated by receptor antagonism in the peripheral region and in the central nervous system. Tropisetron is an early and late potent inhibitor of TCR-mediated T cell activation. Tropisetron specifically inhibited transcription and synthesis of IL-2 of the genes in stimulated T cells. Ttropisetron inhibited NFAT and AP-1 binding to DNA and transcriptional activity. Ttropisetron is a potent inhibitor of PMA and ionomycin-induced NF-(kappa)B activation, but TNF(alpha)-mediated NF-(kappa)B activation is not affected by Ttropisetron. In isolated porcine retinal ganglion cells (RGCs), Tropisetron acts on the α7 nicotinic receptor, providing neuroprotection from glutamate-induced excitotoxicity. Tropisetron acts to reduce p38 MAP kinase levels to inhibit apoptosis. Tropisetron dose-dependently protects retinal ganglion cells (RGCs) from glutamate toxic effects when added to the Culture 1 hour prior to glutamate addition. |
In vivo study | In DBA/2 mice, Tropisetron(1 mg/kg I. p.) significantly ameliorated deficient inhibition of P20-N40 of the auditory evoked potential. |
