Biological Description

Storage & Solubility Information

Description	Ajmalicine (Raubasine) (Raubasine) is a potent adrenolytic agent which preferentially blocks α1-adrenoceptor. Ajmalicine is an reversible but non-competitive nicotine receptor full inhibitor, IC50 = 72.3 μM. Ajmalicine also can be used as anti-hypertensive, and serpentine, with sedative activity。
In vitro	Ajmalicine preferentially blocks α1-adrenoceptor than α2-adrenoceptor[1]. Ajmalicine inhibits contractions in a concentration-dependent manner, IC50=72.3 ± 22.5 μM[2]. Ajmalicine acts preferentially at postsynaptic sites, competitively antagonizes the effect of noradrenaline on postsynaptic alpha-adrenoceptor with a pA2 value of 6.57, blocks the inhibitory effect of clonidine with an pA2 value of 6.2[3].
In vivo	Ajmalicine blocks the pressor action of electrical stimulation and is active against sympathetic stimulation. Ajmalicine (0.5-4 mg/kg) induces a marked dose-dependent inhibition against the pressor response to noradrenaline[1].
