Latrunculin A is a naturally occurring toxin that can be purified from the red sea sponge Latrunculia magnifica. It disrupts actin polymerization and prevents mitotic spindle formation; therefore preventing proper cellular replication. It was discovered that latrunculin A has strong anticancer effects, and it was investigated as a treatment candidate for peritoneal dissemination of gastric cancer.

Sample Use Guides
in mice: Mice bearing peritoneally disseminated MKN45 or NUGC-4 (gastric cancer cells) tumors were prepared by an i.p. inoculation of 1×107 cells in 5% DMSO/0.7 mL PBS. On day 3, 10 and 17 after tumor inoculation, each mouse was given an i.p.injection of latrunculin A. The i.p. injection group were treated with latrunculin A (0.05 mg/kg, 5% DMSO in 0.7 mL PBS, n=14, MKN45; and n=10, NUGC-4), and the control group was treated with 5% DMSO in 0.7 mL PBS (n=19, MKN45; and n=9, NUGC-4). Negative (n=10) group was given latrunculin A without tumor inoculation.
Route of Administration:
Intraperitoneal
It was reported that 25 µM Latrunculin A (LatA) blocked actin polymerization in the capacitated sperm head, resulting in a marked decrease in sperm with relocated IZUMO1 during the A23187-induced acrosome reaction and cumulus layer penetration. Treated sperm also exhibited reduced zona pellucida penetration and fertilizing capacity. Interestingly, LatA-treated sperm present in the perivitelline space of eggs did not show impaired IZUMO1 relocation.
