生物活性

Acutissimalignan B is a natural product. Acutissimalignan B can be isolated from Daphne kiusiana var. atrocaulis (Rehd.) F. Maekawa. Acutissimalignan B can reduce the mRNA expression of inflammatory cytokines (iNOS, TNF-α, IL-1β, and IL-6), inhibit the phosphorylation of IκBα, and inhibit the nuclear translocation of NK-κB p65. Acutissimalignan B shows anti-neuroinflammatory effects[1].

体外研究
(In Vitro)

Acutissimalignan B 可抑制 LPS 诱导的 BV-2 小胶质细胞中 NO 的生成,其 IC₅₀ 为 5.41 μM[1]
Acutissimalignan B (1-10 μM;2 小时) 可降低 LPS 诱导的 BV-2 小胶质细胞中 *iNOS*、*TNF-α*、*IL-1β* 和 *IL-6* 的 mRNA 表达[1]
Acutissimalignan B (1-10 μM;预处理 2 小时) 通过上调 IκBα 水平、降低 IκBα 磷酸化水平及阻断 NF-κB p65 核转位,抑制 LPS 诱导的 BV-2 小胶质细胞中的 NF-κB 信号通路[1]

体内研究
(In Vivo)

Acutissimalignan B (10 mg/kg;灌胃;3 天) 通过抑制小胶质细胞活化、炎症因子表达及 NF-κB 信号通路,在 LPS 诱导的神经炎症小鼠模型中发挥抗神经炎症作用[1]

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

Animal Model: C57BL/6 (male, 18–22 g, LPS-induced via lateral ventricle injection)[1]
Dosage: 10 mg/kg
Administration: i.g.; 3 days
Result: Attenuated microglial activation in the cortex and hippocampus (decreased number and cell body area of Iba-1 positive cells); inhibited mRNA expression of iNOS, TNF-α, IL-1β, and IL-6 in the cortex; increased IκBα protein level, decreased IκBα phosphorylation, and inhibited nuclear translocation of NF-κB p65 in the cortex.

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.
