Cytochalasine b
Actin microfilaments have been widely studied using cytochalasins. Due to their chemical nature, cytochalasins can help researchers understand the importance of actin in various biological processes. The use of cytochalasins has allowed researchers to better understand actin polymerization, cell motility, ruffling, cell division, contraction, and cell stiffness. The use of cytochalasins has been so important to understanding cytoskeletal movement and many other b…

Did you know?
Cytochalasin B, the name of which comes from the Greek cytos (cell) and chalasis (relaxation), is a cell-permeable mycotoxin. It was found that substoichiometric concentrations of cytochalasin B (CB) strongly inhibit network formation by actin filaments. Due to this, it is often used in cytological research. It … See more 1960s Cytochalasin B was first described in 1967, when it had been isolated from moulds by Dr W.B. Turner. Smith et al. found that CB causes multinucleation in cells and … See more Cytochalasins can be isolated from the fungi in which they naturally occur. Originally, they were isolated from Helminthosporium … See more It is suggested that the predominant mechanism of cytochalasin B is the inhibition of actin filament polymerization through binding to the fast-growing (barbed) end of F-actin filaments. An alternative could involve capping proteins. By doing so, CB … See more Actin polymerization studies As cytochalasin B inhibits actin filament polymerization, many cellular processes depending on actin filament functions are affected. Cytokinesis is inhibited, however, mitosis is unaffected. Due to the effects on several cellular … See more Cytochalasin B contains several highly polar keto- and hydroxyl groups and one peripheric lipophilic benzyl unit. See more There are ten possible sites for the in vitro degradation of cytochalasin B. There is not yet any evidence that the same sites are used for degradation in vivo, but evidence has confirmed the … See more Interactions When adding cytochalasin B and the beta-andrenergic agonist (-)-isoproterenol, prostaglandin E1 or cholera toxin to wild type S49 lymphoma cells, cAMP accumulates. Cytochalasin B is unable to transform 3T3-like … See more WebCytochalasin D is a cell-permeable and potent inhibitor of actin polymerization. It disrupts actin microfilaments and activates the p53-dependent pathways causing arrest of the cell cycle at the G1-S transition. It is believed to bind to F-actin polymer and prevent polymerization of actin monomers. [1] References [ edit]
