Mechanism Of Toxicity | Cytochalasins are known to bind to the barbed, fast growing plus ends of microfilaments, which then blocks both the assembly and disassembly of individual actin monomers from the bound end. Once bound, cytochalasin essentially caps the end of the new actin filament. One cytochalasin will bind to one actin filament. By blocking the polymerization and elongation of actin, cytochalasins can change cellular morphology, inhibit cellular processes such as cell division, and cause cells to undergo apoptosis. Cytochalasin B also inhibits glucose transport and platelet aggregation. It blocks adenosine-induced apoptotic body formation without affecting activation of endogenous ADP-ribosylation in leukemia HL-60 cells. |
Toxicity | LD50: 11 mg/kg (Intraperitoneal, Rat). |
