生物活性:
Okadaic acid, a marine toxin, is an inhibitor of protein phosphatases (PP). Okadaic acid has a significantly higher affinity for PP2A (IC50=0.1-0.3 nM), and inhibits PP1 (IC50=15-50 nM), PP3 (IC50=3.7-4 nM), PP4 (IC50=0.1 nM), PP5 (IC50=3.5 nM), but does not inhibit PP2C. Okadaic acid increases of phosphorylation of a number of proteins by inhibiting PP, and acts a tumor promoter. Okadaic acid induces tau phosphorylation.

体内研究:
Okadaic acid 可用于动物建模,构建阿尔兹海默症模型。

体外研究:
Okadaic acid (0-100 nM; 24 h or 48 h) inhibits the proliferation of AGS, MNK-45, Caco 2 cells.?Okadaic acid (10 nM; 8 hours) increases Drp1 phosphorylation and mitochondrial fission in rat cortical neurons.
