Okadaic acid (or okadeic acid, CAS 78111-17-8, C 44 H 68 O 13) is produced by dinoflagelates Dinophysis sp. and Prorocentrum lima. Lipophilic okadaic acid is a potent inhibitor of protein phosphorylase phosphatase-1 and -2A in the cytosol of the mammalian cells that dephosphorylates serine and threonine.

Okadaic acid significantly increased phosphorylation of CaMKII; indicating a major role of PP1 in CaMKII dephosphorylation. Tocris Bioscience is the leading supplier of novel and exclusive tools for life science research with over 30 years' experience in the industry.

At frog junctions, the addition of 1 microM okadaic acid to the extracellular fluid caused almost a doubling of the amplitude of the end-plate potential. The effect of 19 Dec 2016 And stronger acids become negatively charged more easily than weak acids.

CAS 78111-17-8, is a 250 µM solution of Okadaic Acid in DMSO.

Okadaic acid promotes epithelial‐mesenchymal transition of hepatocellular carcinoma cells by inhibiting protein phosphatase 2A.

Marine Toxins Detection by Biosensors Based on Aptamers.

1).It is isolated from the black sponge, Halichondria okadai (Kadota), however, it is thought to be produced by marine dinoflagellates that attach to the black sponge.Okadaic is derived from the name of a Japanese educator Yaichiro Okada. When the structure of okadaic acid was elucidated in 1981, Paul Scheuer at the Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases. This cell permeable inhibitor targets the multiple isoforms of PP1 (IC50 = 10-50 nM), both isoforms of PP2A (IC50 = 0.5 nM) and PP3 (IC50 = 4 nM).[1],[2],[3] It is a very weak inhibitor of PP2B (IC50 > 2 μM) and does not inhibit PP2C or other phosphatases.[1],[3 ]Presumably through Lipid metabolism in visceral fat cells is correlated with metabolic syndrome and cardiovascular diseases. Okadaic-acid, a 38-carbon fatty acid isolated from the black sponge Halichondria okadai , can stimulate lipolysis by promoting the phosphorylation of several proteins in adipocytes.

Lipophilic okadaic acid is a potent inhibitor of protein phosphorylase phosphatase-1 and -2A in the cytosol of the mammalian cells that dephosphorylates serine and threonine. Okadaic acid is an inhibitor of the serine/theorine protein phosphatases PP1 (IC 50 = 15-20 nM) and PP2A (IC 50 = 0.1 nM), exhibiting much greater activity towards the latter. PP2A is completely inhibited at 1-2 nM, compared to greater than 1 µM for PP1 (1). InSolution Okadaic Acid, Prorocentrum sp.

OA was named from the marine sponge Halichondria okadai, from which OA was isolated for the first time. It has also been isolated from another marine sponge, H. malanodocia, as a cytotoxin.

Okadaic acid blocks LLC-PK cells in mitosis LLC-PK cells were treated with various concentrations of okadaic acid (OA) to determine its effect on cell growth. OA was added to the culture media 24 h after cells had been subcultured, and monolayers were maintained for an additional 24-48 h, at which time the number of cells remaining in the

This cell permeable inhibitor targets the multiple isoforms of PP1 (IC50 = 10-50 nM), both isoforms of PP2A (IC50 = 0.5 nM) and PP3 (IC50 Okadaic acid also enhanced the neurite degeneration of NGF-primed PC12 cells, indicating that continual phosphatase activity is required to maintain neurites. Taken together, these results reveal the presence of an okadaic acid-sensitive pathway in neurite outgrowth and imply that protein phosphatase plays a positive role in regulating the neuritogenic effects of NGE. Okadaic acid significantly increased phosphorylation of CaMKII; indicating a major role of PP1 in CaMKII dephosphorylation.

The three main results of the study were as follows: (1) The saxitoxin-group toxins, okadaic acid and analogues, and pectenotoxins were the major phycotoxin residues found in scallops; (2) Six kinds of toxic microalgae were identified, Protoperidinium spp., Gonyaulax spp., and Alexandrium spp. were the dominant taxa; Seven types of potential
