| | AJMALICINE HYDROCHLORIDE Usage And Synthesis |
| Uses | Ajmalicine (Raubasine) hydrochloride is a potent adrenolytic agent which preferentially blocks α1-adrenoceptor. Ajmalicine hydrochloride is an reversible but non-competitive nicotine receptor full inhibitor, with an IC50 of 72.3 μM. Ajmalicine hydrochloride also can be used as anti-hypertensive, and serpentine, with sedative activity[1][2]. | | in vivo | Ajmalicine hydrochloride blocking the pressor action of electrical stimulation and is active against sympathetic stimulation[1].
Ajmalicine hydrochloride (0.5-4 mg/kg) induces a marked dose-dependent inhibition against the pressor response to noradrenaline[1]. | Animal Model: | Male Wistar rats (300-350 g)[1] | | Dosage: | 0.5, 1, 2, and 4 mg/kg | | Administration: | IV, once | | Result: | Induced a marked dose-dependent inhibition against the pressor response to noradrenaline. |
| | IC 50 | α1-adrenergic receptor; α2-adrenergic receptor | | Purification Methods | This hydrochloride crystallises from MeOH or EtOH. Its solubility is 0.315g/100g of H2O at 100o.
