Cytochalasin B inhibits glucose transport [3] and platelet aggregation. It blocks adenosine -induced apoptotic body formation without affecting activation of endogenous ADP -ribosylation in leukemia HL-60 cells. [4] It is also used in cloning through nuclear transfer. See more 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 … 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 … 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 in vitro sites. Degradation is initialized by a periodate cleavage of the … See more Cytochalasins can be isolated from the fungi in which they naturally occur. Originally, they were isolated from Helminthosporium dematioideum. Other producers include See more It is suggested that the predominant mechanism of cytochalasin B is the inhibition of actin filament polymerization through binding to … See more Interactions When adding cytochalasin B and the beta-andrenergic agonist (-)-isoproterenol, prostaglandin E1 or cholera toxin to wild type S49 … See more WebCytochalasin B is a cell-permeable fungal toxin which binds to the barbed end of actin filaments inhibiting both the association and dissociation of subunits. It causes the disruption of actin filaments and inhibition of actin polymerization. ... Effect of cytochalasin B on glucose uptake, utilization, oxidation and insulinotropic action in ...
