Cytochalasin D

产品描述
Cytochalasin D is a selective inhibitor of actin polymerization with with IC50 value of 25 nM [1].Actin is a globular multi-functional protein and found nearly in all eukaryotic cells. it has been shown that actin polymerization plays a pivotal role in chemotaxis and cytokinesis. Cytochalasin D is reported as an inhibitor in the process of actin polymerization via disrupting actin microfilaments and activating p53-dependent pathways which in turn causes the arrest of cell cycle at the G1-S transition [2]. Cytochalasin D is a potent actin polymerization inhibitor. When tested with differentiating neurons, Cytochalasin D slowed down protrusion/retraction cycles and decreased lamellipodia axial motion via inhibiting actin polymerization [1]. In epithelial cell line HEp-2 cells, Cytochalasin D treatment regulated late and very late phases of viral transcription and shut down host transcription through blocking actin polymerization [3]. In the model of IPEC-J2 cells infected with PCV2, Cytochalasin D treatment could suppress PCV2 invasion, replication and release thus inhibited virus invasion [4].References: [1].
