{"product_id":"m12140","title":"Piericidin A","description":"\u003cp style=\"padding-left:1em;\"\u003ePiericidin A (AR-054) is a natural mitochondrial NADH-ubiquinone oxidoreductase (complex I) inhibitor. Piericidin A is a potent neurotoxin and inhibits mitochondrial respiration by disrupting the electron transport system through its action on NADH-ubiquinone reductase. Piericidin A is also a potential quorum-sensing inhibitor that suppresses the expression of the virulence genes of Erwinia carotovora subsp. atroseptica (Eca). Piericidin A is an ADC cytotoxin and has anti-bacterial, anticancer, insecticidal activity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct information\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 2738-64-9\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 415.57\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFormula:\u003c\/strong\u003e C25H37NO4\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSynonym:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"padding-left:1em;\"\u003eAR-054\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eChemical Name:\u003c\/strong\u003e 2-[(2E, 5E, 7E, 9R, 10R, 11E)-10-hydroxy-3, 7, 9, 11-tetramethyltrideca-2, 5, 7, 11-tetraen-1-yl]-5, 6-dimethoxy-3-methylpyridin-4-ol\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eSmiles:\u003c\/strong\u003e C[C@H](\/C=C(\\C)\/C=C\/C\/C(\/C)=C\/CC1=NC(OC)=C(OC)C(O)=C1C)[C@@H](O)\/C(\/C)=C\/C\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChiKey:\u003c\/strong\u003e BBLGCDSLCDDALX-LKGBESRRSA-N\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChi:\u003c\/strong\u003e InChI=1S\/C25H37NO4\/c1-9-18(4)22(27)19(5)15-17(3)12-10-11-16(2)13-14-21-20(6)23(28)24(29-7)25(26-21)30-8\/h9-10,12-13,15,19,22,27H,11,14H2,1-8H3,(H,26,28)\/b12-10+,16-13+,17-15+,18-9+\/t19-,22+\/m1\/s1\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAppearance:\u003c\/strong\u003e Solid Power\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥98% (or refer to the Certificate of Analysis)\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eSolubility:\u003c\/strong\u003e Soluble in DMSO\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eShipping Condition:\u003c\/strong\u003e Shipped under ambient temperature as non-hazardous chemical or refer to Certificate of Analysis\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eStorage Condition:\u003c\/strong\u003e Dry, dark and -20 \u003csup\u003eo\u003c\/sup\u003eC for 1 year or refer to the Certificate of Analysis.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eShelf Life:\u003c\/strong\u003e ≥360 days if stored properly.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eStock Solution Storage:\u003c\/strong\u003e 0 - 4 \u003csup\u003eo\u003c\/sup\u003eC for 1 month or refer to the Certificate of Analysis.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eDrug Formulation:\u003c\/strong\u003e To be determined\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHS Tariff Code:\u003c\/strong\u003e 382200\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow to use\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIn Vitro:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"padding-left:1em;\"\u003eIn a cell free assay, the potency of Piericidin A to inhibit mitochondrial complex I is ∼2 fold smaller than the one of annonacin. In cultured neurons, Piericidin A potently induces the redistribution of phosphorylated tau from the dendrites into the cell soma and induces cell death. The viability of Tn5B1-4 cells is inhibited by Piericidin A in a time- and concentration-dependent manner with IC50 value of 0.061 μM, whilst Piericidin A shows slight inhibitory effect on the viability of HepG2 and Hek293 cells with IC50 value of 233.97 μM and 228.96 μM, respectively. Piericidin A induces apoptosis of Tn5B1-4 cells coincides with a decrease in the mitochondrial membrane potential.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIn Vivo:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"padding-left:1em;\"\u003ePiericidin A (0.5 mg\/kg\/d; for 28 days via osmotic minipumps) significantly increases the number of phospho-tau immunoreactive cells in the cerebral cortex in P301S+\/+ mice. Piericidin A leads to increased levels of pathologically phosphorylated tau only in P301S+\/+ mice. The synaptic density is reduced by Piericidin A treatment in P301S+\/+ mice. Exposure to Piericidin A aggravates the course of genetically determined tau pathology.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReferences:\u003c\/strong\u003e\u003c\/p\u003e\u003col style=\"padding-left:1em;\"\u003e\n\u003cli\u003eMatthias Höllerhage, et al.
