生物活性

Noribogaine hydrochloride is an orally active, blood-brain barrier permeable SERT inhibitor (IC50=50-300 nM) and hERG channel blocker. Noribogaine hydrochloride enhances serotonergic transmission, activates the κ-opioid receptor (OPRK) G protein signaling pathway and inhibits β-arrestin recruitment. Meanwhile, Noribogaine hydrochloride blocks the μ-opioid receptor (OPRM) signaling pathway as well as ion channels associated with cardiac repolarization. Noribogaine hydrochloride induces neuritogenesis, upregulates GDNF mRNA expression, and modulates opioid tolerance. Noribogaine hydrochloride reduces alcohol-seeking behavior in experimental animals, and is widely used in studies related to depression, addiction, alcoholism, and cardiotoxicity[1][2][3][4].

体外研究
(In Vitro)

Noribogaine hydrochloride 是一种 OPRK 的部分激动剂,刺激 [35S]GTPγS 结合的最大效应值 Emax=72%,EC50 为 8.75 µM。Noribogaine hydrochloride 与人 OPRK 的结合亲和力 (Ki=720 nM) 高于与人 OPRM 的结合亲和力 (Ki=1520 nM)[1]

Noribogaine hydrochloride (5-50 μM; 1-6 h) 可强效诱导人神经母细胞瘤细胞系 SH-SY5Y 中 GDNF 的表达呈剂量依赖性升高[2]

RT-PCR[2]

Cell Line: SH-SY5Y human neuroblastoma cells
Concentration: 5-50 μM
Incubation Time: 1 h; 3 h; 6 h
Result: Induced a dose-dependent increase in GDNF expression similar to ibogaine, with a statistically significant effect for the 3-hour incubation.
Increased GDNF expression at 1 hour and 6 hours of incubation.
体内研究
(In Vivo)

Noribogaine hydrochloride (10-40 mg/kg; i.p.) 在 10 和 20 mg/kg 剂量下可恢复吗啡耐受小鼠的吗啡抗伤害感受活性,在 40 mg/kg 剂量下可增强吗啡诱导的镇痛作用,并可预防吗啡镇痛耐受的形成[1]
Noribogaine hydrochloride 可在大鼠体内对多种成瘾剂的自身给药行为产生持久的抑制作用[1]
Noribogaine hydrochloride (40 mg/kg;i.p.;单次) 在大鼠单次腹腔注射 40 mg/kg Ibogaine 后可达到较高的脑内浓度 (-20 μM),且具有优异的血脑屏障通透性,并可诱导中枢介导的催乳素释放[1]
Noribogaine hydrochloride (1-100 μM;i.p.;持续 2 分钟;操作性自给药实验开始前 3 小时) 可显著、呈剂量依赖性且持久地降低有高自愿饮酒史大鼠的操作性乙醇自给药行为[2]
Noribogaine (20-40 mg/kg;i.p.;单次给药) hydrochloride 在大鼠腹腔注射单次 40 mg/kg 给药后 0.5 小时可诱导剂量依赖性的类抗抑郁作用,而给药后 3 小时或 20 mg/kg 剂量组未观察到显著作用[3]

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.
