Latrunculin A

Latrunculin A (LAT-A), found in the red sea sponge Latrunculia magnifica, is a G-actin polymerization inhibitor. Latrunculin A binds to actin monomers and inhibits polymerization of actin with Kds of 0.1, 0.4, 4.7 μM and 0.19 μM for ATP-actin, ADP-Pi-actin, ADP-actin and G-actin, respectively. Latrunculin A has effective anti-metastatic properties for cancer research. Latrunculin A blocks cell migration[1][2][3][4][5][6].
