In Vivo
The effects of Rhynchophylline, Corynoxeine, and Isocorynoxeine, isorhynchophylline-related alkaloids present are tested in Uncaria species, on 5-MeO-DMT-induced head-twitch behaviour in reserpinized mice. Neither Rhynchophylline [H=1.369, P=0.504] nor Corynoxeine [H=0.242, P=0.886] affects the behaviour, while Isocorynoxeine significantly attenuates it at 30 mg/kg (i.p.) [H=7.582, P<0.01].
In Vitro
Isocorynoxeine inhibits 5-HT2A receptor-mediated 5-HT currents. Isocorynoxeine prefer to interact with 5-HT2A receptors rather than with 5-HT2C receptors in the brain. Isocorynoxeine exhibits less potent inhibitory activity (with IC50 values of > 100 μM) against the 5-HT2C receptor-mediated response than the 5-HT2A receptor-mediated response in oocytes. Isocorynoxeine dose-dependently and competitively inhibits 5-HT-evoked currents in Xenopus oocytes expressing 5-HT2A receptors, but has less of a suppressive effect on those in oocytes expressing 5-HT2C receptors.
