Cytochalasin D (also known as Zygosporin A) is a cell-permeable fungal metabolite and a potent inhibitor of actin polymerization. It binds to G-actin, thereby disrupting the G-actin–cofilin interaction and preventing cofilin association with F-actin. Through this mechanism, Cytochalasin D reduces both actin polymerization and depolymerization rates in living cells, leading to profound effects on cytoskeletal organization and cell morphology. In addition, Cytochalasin D suppresses exosome release, consequently decreasing survivin levels within the tumor microenvironment. It also promotes phosphorylation and cytoplasmic retention of YAP, implicating it in the regulation of mechanotransduction and tumor cell signaling.
