Cytochalasin D is a cell-permeable fungal toxin that acts as a potent inhibitor of actin polymerization; disrupts actin microfilaments; activates the p53-dependent pathways. It is about 10-fold more effective than Cytochalasin B and does not inhibit monosaccharide transport across cell membranes. Inactivates low conductance K+ channels. Modulates CD4 cross-linking in T-lymphocytes and increases intracellular Ca2+levels. Exhibits antitumor activity. Induces apoptosis. MW: 507.6. Purity ≥95%
