CP-690550 doesn"t have potent activity against 30 other kinases (all median IC50 > 3000 nM). CP-690,550 inhibits IL-2–induced proliferation with 30-fold greater potency than its effects on GM-CSF–induced proliferation [1]. CP-690550 effectively inhibits a murine mixed lymphocyte reaction (MLR) (IC50 = 91 nM) [2]. CP-690550 potently inhibits IL-4 induced upregulation of CD23 (IC50=57 nM) and class II major histocompatibility complex (MHCII) expression (IC50=71 nM) on murine B cells [3]. in vivo: In a murine model of heterotopic heart transplantation (DBA2 donor heart into C57/BL6 host), CP-690550 results in a dose-dependent increase in survival of transplanted hearts.The EC50 (drug concentrati...Purity: >98%Molecular formula: C16H20N6OMolecular Weight: 312.37Storage Instructions: Two years -20°C Powder, 2 weeks4°C in DMSO,6 months-80°C in DMSOReferences: for more information, please visit images/AffixScientific/
