Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases. Okadaic acid induces tau phosphorylation in SH-SY5Y cells in an estrogen-preventable manner Okadaic acid is a naturally occurring polyether toxin that was originally derived from marine dinoflagellates, Prorocentrium spp..Okadaic Acid is a reversible, potent and selective inhibitor of two serine threonine protein phosphatases: PP2A-C (PP2A) which is inhibited completely at 1 nM and PP1 which is inhibited at higher concentrations (IC 50 = 10-15 nM). Okadaic acid is a causative agent of diarrhetic shellfish poisoning isolated from the sponge Halichondria Okadai. Okadaic Acid exhibits various activities as follows: Contractile effect on smooth muscles in Ca 2+ free solution. Non-TPA type promoting agent of carcinogenesis. Okadaic acid is extracted from black sponges of the genus Halichondria. Okadaic acid is a non-comepetitive, selective and reversible serine/threonine-specific protein phosphatases 1 ( PP1 ), PP2A and PP3 inhibitor with IC50 s of 10-15 nM, 0.5 nM and 4 nM, respectively.

Okadaic acid

产品使用信息. 冈田酸以冻干粉形式保存。如需 1 mM 原液,则在 31.1 μl DMSO 中放入 25 μg 重新配制。使用浓度和处理时长根据所需效果进行调整,但通常的使用浓度为 10-1000 nM,时长 15-60 分钟。 Okadaic acid is a polyether fatty acid. It is a marine toxin produced by the genera of Prorocentrum and Dinophysis. Application Okadaic acid from Prorocentrum concavum has been used as a phosphatase inhibitor: • to inhibit protein phosphatase 2 in spermatocytes culture • to treat SH-SY5Y cells to prevent dephosphorylation to maintain tau Okadaic acid (OKA) is one of the main polyether toxins produced by marine microalgae which causes diarrhetic shellfish poisoning. It is a selective and potent inhibitor of serine/threonine phosphatases 1 and 2A induces hyperphosphorylation of tau in vitro and in vivo.

Okadaic Acid: Equivalent Term Ocadaic Acid: CAS Registry Number 78111-17-8 Definition : A specific inhibitor of phosphoserine/threonine protein phosphatase 1 and 2a. It is also a potent tumor promoter. It is produced by DINOFLAGELLATES and causes diarrhetic SHELLFISH POISONING.
