Cytochalasin D (Synonyms: 細(xì)胞松弛素D; Zygosporin A; NSC 209835)

生物活性

Cytochalasin D (Zygosporin A) is a potent actin polymerization inhibitor, could be derived from fungus. Cytochalasin D has cell-permeable activity. Cytochalasin D inhibits the G-actin–cofilin interaction by binding to G-actin. Cytochalasin D also inhibits the binding of cofilin to F-actin and decreases the rate of both actin polymerization and depolymerization in living cells. Cytochalasin D can reduce exosome release, in turn reducing the amount of survivin present in the tumour environment. Cytochalasin D induces phosphorylation and cytoplasmic retention of Yap

體外研究(In Vitro)

Cytochalasin D (3 and 10 μM; 30 min) causes retraction and arborization of COS-7 cells and conversion of F-actin from long fibers to punctate structures^[1].
Cytochalasin D (0.3, 1, 3 and 10 μM; 30 min) concentration-dependently decreases the rate of actin depolymerization in COS-7 cells^[1].
Cytochalasin D (1 μM; NIH3T3 cells) disrupts stress fibers, induces phosphorylation of Yap, while cells maintains original area and lost nuclear Yap localization
