Cytochalasines
WebOct 13, 2024 · Scientific background . Cytochalasins are a group of fungal toxin metabolites which bind to actin and alter its polymerization. Cytochalasins bind to the barbed end of the actin filament and prevent both the association and dissociation of actin subunits by inhibiting cell microtubule formation, cell division and cell migration. 1-4 … WebAdult toxicity, embryo lethality, and teratogenicity of cytochalasins D and E (CD and CE) were determined for A/J, C57BL/6JH, aeae, and OELN mouse strains. The adult LD50 for CD (1.9-2.6 mg/kg) and CE (3.1-3.3) were similar for the strains. Although adult LD50s were similar, the embryo lethality and …

WebCytochalasins A, B, D, and E, and Dihydrocytochalisin B are stored at –20 °C. Cytochalasin A, C, D, and E should be stored in the dark since the conjugated double bond undergoes slow isomerization from trans to cis in the presence of light. Cytochalasin B is a solid believed to be photostable in the solid form and reasonably stable in solution.
