Strictosamide possesses antibacterial and antiviral activities, it also may have important effects on inflammation and inflammatory pain. Strictosamide is slightly toxic to Charles River mouse (LD(50)=723.17 mg/kg), producing CNS depression and kidney toxicity. Strictosamide has nonsignificant in vitro and in vivo effect on kidney Na(+),K(+)-ATPase activity but produced an in vivo increase of Na(+),K(+)-ATPase activity of brain.
Gardneramine has a mild central depressive effect. Gardneramine and hirsutine show a local anesthetic action, they also can inhibit the ganglionic transmission of the dog urinary bladder and that the blockade of the nicotinic receptor plays a main role.
Mesuaxanthone A and mesuaxanthone B are two yellow pigments.They produce varying degrees of C.N.S. depression characterised by ptosis, sedation, decreased spontaneous motor activity, loss of muscle tone, potentiation of pentobarbitone sleeping time and ether anaerthesia in mice and rats; they also exhibit anti inflammatory activity both by intraperitoneal and oral routes in rats.
Reticuline is a key compound in the biosynthetic pathway for isoquinoline alkaloids in plants, which include morphine, codeine and berberine. Reticuline possesses potent central nervous system depressant action, it (50-100 mg/kg i.p.) can produce alteration of behaviour pattern, prolongation of pentobarbital-induced sleep, reduction in motor coordination and D-amphetamine-induced hypermotility and suppression of the conditioned avoidance response. (S)-Reticuline can elicit vasorelaxation probably due to the blockade of the L-type voltage-dependent Ca(2+) current in rat aorta, the effect may contribute to the potential cardioprotective efficacy of (S)-reticuline.
DL-Homocysteic acid application disrupts calcium homeostasis and induces degeneration of spinal motor neurons in vivo.
