Description

General description

Cytochalasin D is a cell-permeable fungal toxin. It disrupts actin microfilaments and activates the p53-dependent pathways causing arrest of the cell cycle at the G1-S transition. Cytochalasin D inhibits smooth muscle contraction and insulin-stimulated but not basal transport of glucose.

Cytochalasin D (CytoD) is commonly used to inhibit actin dynamics and study its role in cellular processes. This fungal-derived small organic compound acts as an inhibitor of the interaction between G-actin and cofilin by binding to G-actin. Additionally, CytoD inhibits the binding of cofilin to F-actin and reduces the rate of actin polymerization and depolymerization in living cells.

Application

Cytochalasin D has been used:

• to treat H9c2 cells to study the relationship between cell stiffness and the F-actin cytoskeleton
• as inhibitor of receptor-mediated endocytosis to treat oligodendrocyte precursor cells (OPCs) to investigate the effect of inhibiting specific extracellular vesicle (EV) uptake pathways
• in in vitro embryo culture to artificially activate oocytes

Biochem/physiol Actions

Potent inhibitor of actin polymerization; disrupts actin microfilaments; activates the p53-dependent pathways; inhibits smooth muscle contraction; inhibits insulin-stimulated glucose transport.
