Latrunculin A  (Synonyms: LAT-A)

Cat. No.: HY-16929 Purity: ≥97.0%
COA Handling Instructions

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.

Description

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].

IC50 & Target

Kd: 0.1 μM (ATP-actin), 0.4 μM (ADP-Pi-actin), 4.7 μM (ADP-actin), 0.19 μM (G-actin)[2]

In Vitro

Latrunculin A (50-1000 nM) exhibits potent anti-invasive activity against human prostate cancer PC-3M cells, inhibits PC-3M-CT+ spheroids disaggregation and cell migration[3].
? Latrunculin A (3-30 μM) inhibits hypoxia-induced HIF-1 activation with an IC50 value of 6.7 μM in human breast carcinoma T47D cells[3].
? Latrunculin A (0-0.2 μM, 4 hours) has a significant inhibitory effect on HuR levels at high concentrations such as 0.2 μM in human hepatoma HepG2 cells while inhibits HuR only at 0.02 μM but no inhibitory effect at high concentrations in human hepatoma Huh7 cells[4].
? Latrunculin A (0.1 μM, 24 hours) can lead to a significant decrease in cell migration and has an inhibitory effect on cell proliferation in human hepatoma cell lines HepG2[4].

In Vivo

Latrunculin A (intraperitoneal injection, 0.05 mg/kg, three doses in the first 20 days, 120 days) has strong antitumor effect in male BALB/c nude mice models infected with adenocarcinoma (MKN45) or carcinoma (NUGC-4)[5].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
