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).
Dihydrocytochalasin B (H2CB) 是一种细胞分裂抑制剂,抑制胞质分裂并改变细胞的形态,破坏 Swiss 3T3 小鼠成纤维细胞的肌动蛋白结构,抑制血清生长因子在静止培养物中刺激 DNA 合成的能力,瓦解肌动蛋白细胞结构并抑制 3T3 细胞中 DNA 合成的启动。低剂量的 H2CB 会导致细胞变圆和肌动蛋白微丝束的丢失。
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
1-Oleoyl-2-palmitoyl-rac-glycerol (1,2-OP) is a diacylglycerol containing oleic acid at the sn-1 position and palmitic acid at the sn-2 position. It enhances the inhibition of superoxide anion production by cytochalasin B when used at a concentration of 10 μM. The concentration of 1,2-OP decreases from 25.7 to 11.15% during the dry-curing process of Iberian ham.
Sydowinin B is a xanthone polyketide that has been found inA. sydowiiand has immunosuppressant activity.1It inhibits LPS- or concanavalin A-induced proliferation of isolated mouse splenic lymphocytes (IC50s = 19.2 and 20.8 μg ml, respectively).2Sydowinin B inhibits superoxide generation in, and elastase release from, isolated human neutrophils induced by cytochalasin B and N-Formyl-Met-Leu-Phe with IC50values of 21.2 and 12.62 μM, respectively.3
L-858,051 is a water-soluble analog of forskolin , a cell-permeant activator of adenylate cyclase. L-858,051 activates adenylate cyclase (EC50 = 3 μM), inhibits glucose transport, and blocks cytochalasin B binding in rat adipocyte membranes. L-858,051 is used to activate adenylate cyclase and initiate signaling through elevated cAMP synthesis in a variety of cell types in culture.
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).
