Cytochalasin B is a cyto-permeable mycotoxin, and it is isolated from an ascomycete fungus belonging to the Phoma genus[1-2]. Cytochalasin B is able to inhibit the formation of actin microfilaments through a direct effect on the polymerization of the cytoskeletal protein. By binding the fast-growing end of F-actin and interacting with capping proteins, influences the nucleation-elongation of actin microfilaments[3-4].
Cytochalasin B (0.1-10 µM; 0-72 h) influenced the metabolism, proliferation, and morphology of hASCs in a dose-dependent manner, in association with progressive disorganization of actin microfilaments[5]. Cytochalasin B is capable of inducing DNA fragmentation in a number of cells lines[6]. Cytochalasin B (10-8-10-1M; 24-96 h) effectively inhibited U251 cell proliferation in a dose- and time-dependent manner. Cytochalasin B increased the proportion of cells in the G2/M phase in a dose-dependent manner, thus increasing the mitotic index and decreasing CDC2 and cyclin B1 protein levels[7].
Cytochalasin B(Cytochalasins B was prepared in suspension form in 2% carboxymethyl cellulose 1% tween 20 (CMC/Tw); i.p.;10, 25, or 50 mg/kg; 8days ) dose-dependently increases the life expectancy of Balb/c mice bearing with P388/ADR leukemias[8].Cytochalasin B(5 µg/ml Cytochalasin B; 30 min) treatment of mouse oocytes during intracytoplasmic sperm injection (ICSI) increases embryo survival without impairment of development[9].
