Actin disruption is used to study cell functions in vitro (e.g., migration, endocytosis) and in vivo (e.g., tumor cell invasion). Latrunculin A is a bioactive 2-thiazolidinone macrolide derived from sponges that sequesters G-actin and prevents F-actin assembly. It binds monomeric actin with 1:1 stoichiometry and can...

Isolated from Latrunculia magnifica. Cell permeable marine toxin. Disrupts microfilament-mediated processes. Actin polymerization inhibitor in vitro and in vivo by the formation of a 1:1 complex with monomeric G-actin. Potent phagocytosis inhibitor. Anticancer compound. Suppresses hypoxia-induced HIF-1 activation in...
