资料参考

Cytochalasin B is a cell-permeable mycotoxin which binds to the barbed end of actin, reversibly inhibiting the elongation and shortening of actin filaments, with Kd value of 1.4-2.2 nM for F-actin[1].

Cytochalasin B (0.1-10 μM) shows inhibitory effect on multiple murine cancer cell lines[2]. In addition, Cytochalasin B accelerates the transformation from F-actin to G-actin, lowering the content of F-actin and significantly increasing G-actin bands during postmortem conditioning[3].

Cytochalasin B dose-dependently increases the life expectancy of Balb/c mice bearing with P388/ADR leukemias. Cytochalasin B at 50 mg/kg produces 10 % long-term survival in the multidrug resistant P388/ADR cohort, and 40 % long-term survival in the drug sensitive P388/S cohort[2].
