cytochalasin b

Cytochalasin B is a mycotoxin binding to the barbed end of actin filaments. It can disrupt the formation of actin polymers (Kd: 1.4-2.2 nM for F-actin).

Cytochalasin A is a cell-permeable fungal toxin and is an oxidized derivative of cytochalasin B. Cytochalasin A is an inhibitor of HIV-1 protease (IC50 = 3 μM), inhibits actin polymerization and interferes with microtubule assembly by reacting with sulfhy

Evofolin B 是从Zanthoxylum ailanthoides 的茎皮中分离出来的天然化合物。Evofolin B 对人类中性粒细胞对甲酰-L-蛋氨酸-L-亮氨酸-L-苯丙氨酸/cytochalasin B（fMLP/CB）产生的超氧阴离子有抑制作用。

2'-Hydroxydaidzein 是一种在植物中发现的异黄酮类植物素，是一种天然化合物。2'-Hydroxydaidzein 具有抗氧化活性，主要由o -氢键解离焓(BDE)和氢原子转移(HAT)机制驱动。2'-Hydroxydaidzein 抑制炎症细胞中的化学介质，可能对治疗和预防与化学介质产生过多有关的中枢和外周炎症性疾病有作用。2'-Hydroxydaidzein 对大鼠中性粒细胞和formyl-Met-Leu-Phe/cytochalasin B（fMLP/CB）的释放具有抑制作用，IC（50）值分别为2.8+/-0.1和5.9+/-1.4 microM。

3'-O-Methylmurraol may have potential anti-inflammatory activity, it exhibits inhibition (IC50 ≤ 7.31 ug/mL) of superoxide anion generation by human neutrophils in response to formyl-l-methionyl-l-leucyl-l-phenylalanine/cytochalasin B (fMLP/CB).
