Chaetoglobosin Vb是一种新型的细胞毒素生物碱，具有抗炎和抗氧化活性。Chaetoglobosin Vb能够抑制LPS刺激引起的氧化应激，减少反应性氧物质的产生并增加抗氧化酶超氧化物歧化酶（SOD）的表达。Chaetoglobosin Vb显著降低了LPS诱导的诱导型一氧化氮合酶（iNOS）和环氧合酶-2（COX-2）的基因和蛋白质表达，同时减轻了促炎细胞因子（如TNF-α、IL-6和IL-1β）的产生。Chaetoglobosin Vb通过TLR4介导的MyD88依赖性信号通路和TRIF依赖性信号通路发挥其生物学活性，具体表现为抑制p38、ERK、JNK MAPK的磷酸化以及NF-κB p65亚基转移到细胞核的过程。Chaetoglobosin Vb在25-100 μM的浓度范围内表现出无细胞毒性的影响，且剂量依赖性促进SOD酶活性及p38、ERK1/2和JNK的磷酸化。

生物活性

Chaetoglobosin Vb is a novel cytotoxic alkaloid with anti-inflammatory and antioxidant activities. Chaetoglobosin Vb can inhibit oxidative stress induced by LPS stimulation, reduce the production of reactive oxygen species and increase the expression of the antioxidant enzyme superoxide dismutase (SOD). Chaetoglobosin Vb significantly reduced the gene and protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) induced by LPS, and alleviated the production of proinflammatory cytokines such as TNF-α, IL-6 and IL-1β. Chaetoglobosin Vb exerts its biological activity through the TLR4-mediated MyD88-dependent signaling pathway and the TRIF-dependent signaling pathway, which is specifically manifested by inhibiting the phosphorylation of p38, ERK, and JNK MAPK and the translocation of NF-κB p65 subunit to the nucleus. Chaetoglobosin Vb showed no cytotoxic effect in the concentration range of 25-100 μM and promoted SOD enzyme activity and phosphorylation of p38, ERK1/2 and JNK in a dose-dependent manner[1].

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.
