Andrographolide (Andro) 穿心莲内酯是通过共价修饰 p50 的半胱氨酸 62 来影响 NF-κB 活性的小拮抗剂。Andrographolide (Andro) 穿心莲内酯是一种双环二萜内酯，主要由穿心莲 (Andrographis paniculate) 产生。Andrographolide (Andro) 穿心莲内酯抑制刺激的内皮细胞中 NF-κB 的活化，降低细胞粘附分子 E-选择素的表达，阻止 E-选择素介导的白细胞粘附，但对 IκBα 降解，p50 和 p65 核转位没有影响。

Background:

Andrographolide (Andro) is a small antagonist for NF-κB activation by covalent modifying reduced cysteine 62 of p50. Andrographolide is a bicyclic diterpenoid lactone mainly produced from the plant Andrographis (Andrographis paniculate).Andrographolide suppresses the activation of NF-κB in stimulated endothelial cells, which reduces the expression of cell adhesion molecule E-selectin and prevents E-selectin-mediated leukocyte adhesion, but has no effect on IκBα degradation, p50 and p65 nuclear translocation[1].

Andrographolide (15 μM; 12 hours) inhibited the luciferase activities induced by TNF-α in a time-dependent manner with an IC50 of 10 μM[1]. Cell Proliferation Assay[1] Cell Line: 293 cells
