Latrunculin A

    • Cell permeable marine toxin [1].
    • Disrupts microfilament-mediated processes [2].
    • Actin polymerization inhibitor in vitro and in vivo by the formation of a 1:1 complex with monomeric G-actin [1, 2, 3, 6].
    • Depolymerizes actin filaments (F-actin) [3].
    • Potent phagocytosis inhibitor [4].
    • Anticancer compound [7, 8]. Suppresses hypoxia-induced HIF-1 activation in tumor cells [7]. Inhibits tumor cell invasion [7].
    • Acts via a different mechanism than cytochalasins.
