| Background | Latrunculin A is an inhibitor. In addition, latrunculin A was able to bind to actin monomers and inhibit actin aggregation. |
| Biological Activity | Latrunculin A 来自 Latrunculia magnifica，是一种 G 肌动蛋白聚合抑制剂，可与肌动蛋白单体结合，抑制肌动蛋白的聚合，对 ATP-肌动蛋白、ADP-Pi-肌动蛋白、ADP-肌动蛋白和 G-肌动蛋白的 Kds 分别为 0.1、0.4、4.7 μM 和 0.19 μM。[1-2] |
| In Vitro | Latrunculin A bound ATP-actin monomers with a higher affinity(Kd = 0.1 μM)than ADP-Pi-actin(Kd = 0.4 μM)or ADP-actin(Kd = 4.7 μM). Latrunculin A binds weakly to actin filaments with a Kd >100 μM.[1] Latrunculin A and carbamates 4- 6 displayed potent anti-invasive activity against the human highly metastatic human prostate cancer PC-3M cells in a Matrigel assay at a concentration range of 50 nM to 1 microM. Latrunculin A(500 nM)decreased the disaggregation and cell migration of PC-3M-CT+ spheroids by 3-fold. Latrunculin A(IC 50 6.7 microM)suppress hypoxia-induced HIF-1 activation in T47D breast tumor cells.[3] Latrunculin A caused a dose- and time-dependent reduction in the high cytoplasmic HuR content of HepG2 and Huh7 hepatocellular carcinoma(HCC)cells.[4] Latrunculin A induced acute cell injury and programmed cell death through activating the caspase-3/7 pathway.[5] |
| In Vivo | Intraperitoneal(i.p.)injection of latrunculin A significantly improved survival rate in mice without any major side-effects.[5] |
