COA 产品使用指南

Mitragynine ((-)-Mitragynine) 是一种精神类化合物。Mitragynine 对 μ-阿片受体 (μ-opioid receptors) 有较高的亲和力,通过作用于脊椎上的 μ- 和 δ- 阿片受体来发挥镇痛作用。Mitragynine 可抑制神经母细胞瘤细胞 Ca2+ 通道 (calcium channel) 电流,也能抑制豚鼠输精管对电刺激的抽搐反应。具有止痛、止咳、止泻、肾上腺素能和抗疟活性。

生物活性

Mitragynine ((-)-Mitragynine) is a psychoactive compound. Mitragynine has a high affinity to μ-opioid receptors, acts at supraspinal μ- and δ-opioid receptors for its antinociceptive effects. Mitragynine can inhibit Ca2+ channel currents in neuroblastoma cells and inhibit the twitch response to electrical stimulation in guinea-pig vas deferens. Analgesic, antitussive, antidiarrheal, adrenergic, antimalarial activity[1][2].

IC50 & Target[1]

L-type calcium channel

 

μ Opioid Receptor/MOR

 

δ Opioid Receptor/DOR

 

体外研究
(In Vitro)

Mitragynine (1 μM) blocks T- and L-type Ca2+ channel currents in N1E-115 neuroblastoma cells[2].
Mitragynine (10 nM-1 μM) reduces KCl-induced Ca2+ influx in neuroblastoma cells[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Mitragynine (300 nM-10 μM) inhibits the twitch response to electrical stimulation in guinea-pig vas deferens in a concentration-dependent manner[2].
Mitragynine (3-10 μM) inhibits nicotine-induced (1 mM) contraction of guinea-pig vas deferens in a concentration-dependent manner[2].
Mitragynine (1.5 mg/kg for IV, 50 mg/kg for PO, single dosage) exhibits a biphasic elimination from plasma, and the oral absorption is slow, prolonged and incomplete[3].

Animal Model: Male Sprague-Dawley rats (12-16 weeks old, 280-315 g)[3]
Dosage: 1.5 mg/kg for IV, 50 mg/kg for PO
Administration: IV or PO, single dosage (Pharmacokinetic analysis)
Result: Exhibited a biphasic elimination from plasma, and the oral absorption was slow, prolonged and incomplete, with a calculated absolute oral bioavailability value of 3.03%.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
