Cytochalasin B

Cytochalasin B is a cell-permeable mycotoxin which binds to the barbed end of actin, reversibly inhibiting the elongation and shortening of actin filaments. By disrupting actin polymerization, cytochalasin B blocks diverse cellular functions, including cell division, migration, phagocytosis, exocytosis, chemotaxis, and glucose transport. Cytochalasin B is broadly used in cytological studies involving any of these many processes that depend on actin polymerization.Formal Name: (3E,5R,9R,11E,12aS,13S,15S,15aS,16S,18aS)-6,7,8,9,10,12a,13,14,15,15a,16,17-dodecahydro-5,13-dihydroxy-9,15-dimethyl-14-methylene-2H-oxacyclotetradecino[2,3-d]isoindole-2,18(5H)-dione.
