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.

| 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]. |

Solution Preparation Table | ||||||||||||||||
DMSO
| ||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
