Cytochalasin D (Zygosporin A; NSC 209835) 是一种有效、细胞渗透性的肌动蛋白聚合抑制剂,由真菌产生,通过绑定 G-actin 抑制 G-actin–cofilin 的相互作用。Cytochalasin D 还能抑制 cofilin 与 F-actin 的结合,降低了活细胞中肌动蛋白聚合和解聚的速率。Cytochalasin D 可以减少外泌体的释放,进而减少肿瘤环境中 survivin 的量。 Cytochalasin D 诱导 YAP 磷酸化,阻止其核易位保留在胞质中。
生物活性
Cytochalasin D (Zygosporin A; NSC 209835) is a potent and cell-permeable inhibitor of actin polymerization derived from fungus, inhibits the G-actin–cofilin interaction by binding to G-actin. Cytochalasin D (Zygosporin A; NSC 209835) also inhibits the binding of cofilin to F-actin and decreases the rate of both actin polymerization and depolymerization in living cells[1][2][3].Cytochalasin D can reduce exosome release, in turn reducing the amount of survivin present in the tumour environment[4]. Cytochalasin D induces phosphorylation and cytoplasmic retention of YAP[5].
