{"product_id":"m23358","title":"Sephin1","description":"\u003cp style=\"padding-left:1em;\"\u003eSephin1 is a selective inhibitor of stress-induced PPP1R15A and targets disease associated with accumulation of misfolded protein.  PPP1R15A is a regulator subunit of protein phosphatase 1 and regulates stress-induced eIF2α (α subunit of eukaryotic translation initiation factor 2). It brings PP1 (serine\/threonine-protein phosphatase) to dephosphorylate eIF2α. Phosphorylation of eIF2α reduces protein synthesis and prevents the accumulation of misfolded protein in ER (endoplasmic reticulum). Thus inhibiting PPP1R15A prolongs the phosphorylation of eIF2α, and benefits the treatment for protein misfolding disease.  In cells treated with 5μm Sephin1 for 6 hours, Sephin1 specifically disrupted the PPP1R15A-PP1c complex without affecting PPP115B-PP1c complex. As a consequence, Sephin1 prolonged eIF2a phosphorylation in HeLa cells after stress (*2.5 μg\/ml tunicamycin treatment) and delayed translational recovery. Sephin1 recused cell from cytotoxic ER stress* in wild-type cell but not the PPP1R15A mutant cell.  In mice administrated orally with 1-5mg\/kg Sephin1 for given time, Sephin1 exhibited no adverse effects on rotarod performances, total body weight gain or memory. Treating MPZ (Deletion of serine 63 of myelin protein zero) mutant mice with 1mg\/kg orally twice a day, prevented the molecular, morphological and motor defects. Oral treatment of 5 mg\/kg of Sephin1 once a day, prevented motor deficits, motor neuron loss and the molecular defects in SOD1 (Mutant and misfolding-prone superoxide dismutase 1) mutant mice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct information\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 13098-73-2\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 196.64\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFormula:\u003c\/strong\u003e C8H9ClN4\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eChemical Name:\u003c\/strong\u003e N-[(E)-[(2-chlorophenyl)methylidene]amino]guanidine\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eSmiles:\u003c\/strong\u003e NC(=N)N\/N=C\/C1=CC=CC=C1Cl\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChiKey:\u003c\/strong\u003e PDWJALXSRRSUHR-LFYBBSHMSA-N\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChi:\u003c\/strong\u003e InChI=1S\/C8H9ClN4\/c9-7-4-2-1-3-6(7)5-12-13-8(10)11\/h1-5H,(H4,10,11,13)\/b12-5+\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\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 ≥12 months 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\u003eProducts are for research use only.
