生物活性

Vitedoamine A is a Phenylnaphthalene-type lignan alkaloid. Vitedoamine A can be isolated from Vitex negundo. Vitedoamine A inhibits the activity of IKKβ with an IC50 value of 39 μM. Vitedoamine A could inhibit the transcriptional activity of NF-κB, and suppress the production of NO and reduce the expressions of inflammatory cytokines (IL-1β, IL-6, and TNF-α). Vitedoamine A inhibits the phosphorylation of IKKα/β and p65, and prevents the degradation of IκBα. Vitedoamine A possesses anti-rheumatoid arthritis capacity[1].

体外研究
(In Vitro)

Vitedoamine A (5-60 μM) 可直接靶向 IKKβ 并抑制其酶活性,IC50 为 39 μM[1]
Vitedoamine A (1-80 μM;对于细胞活力检测,48 h) 可在 TNF-α 刺激的 293 T 细胞中剂量依赖性地抑制 NF-κB 转录活性,且不会降低细胞活力[1]
Vitedoamine A (1-40 μM; 4 h) 通过抑制 LPS/TNF-α 诱导的 RAW264.7 细胞中 IKKα/β 的磷酸化来抑制 NF-κB 的激活[1]
Vitedoamine A (1-40 μM; 4 h) 在 IL-1β 刺激的人成纤维样滑膜细胞中发挥抗类风湿关节炎 (RA) 活性,其机制为靶向 IKKβ 以抑制 NF-κB 通路激活并减少炎性细胞因子的产生[1]

Western Blot Analysis[1]

Cell Line: LPS/TNF-α-induced RAW264.7 cells
Concentration: 1, 10, 20, 40 μM
Incubation Time: 4 h
Result: Decreased LPS-induced expression of p-p65 and inhibited LPS-induced degradation of IκB; Inhibited the expression of p-IKKα/β, but had not effects on the expressions on IKKα and IKKβ; Had no effect on p-TAK1 expression induced by LPS; Decreased TNF-α-induced p-IKK expression level, and inhibited p-p65 expression level and IκB degradation.

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.
