產(chǎn)品名稱:PIK-90, Free Base 產(chǎn)品貨號(hào):LC P-9050 產(chǎn)品規(guī)格:10 MG PIK-90 is a synthetic phosphoinositide 3-kinase (PI3K) inhibitor. The p110α isoform of PI3K is the primary insulin-responsive PI3K in cultured cells. Compounds targeting p110α block the acute effects of insulin treatment in vivo. A p110β inhibitor has no effect on insulin treatment. Zachary, A., et al. "A Pharmacological Map of the PI3-K Family Defines a Role for p110α in Insulin Signaling." Cell 125: 733-747 (2006). PIK-90 is a class I p110α inhibitor (IC50 = 11 nM). It also blocks p110γ (IC50 = 18 nM), and to a lesser extent p110δ (IC50 = 58 nM) and p110β (IC50 = 350 nM). Niedermeier, M., et al. "Isoform-selective phosphoinositide 3'-kinase inhibitors inhibit CXCR4 signaling and overcome stromal cell-mediated drug resistance in chronic lymphocytic leukemia: a novel therapeutic approach." Blood 113: 5549-5557 (2009). PIK-90, PI-103, or IC87114 inactivated PI3K and led to uncontrolled sequential switching from IgG1 to IgE. Zhang, T.T., et al. "Genetic or pharmaceutical blockade of p110δ phosphoinositide 3-kinase enhances IgE production." J. Allergy Clin. Immunol. 122: 811-819 (2008). PIK-90 induced the proliferative arrest of a panel of glioma cell lines. Combining PIK-90 and the mTORC1 inhibitor rapamycin induced a profound cell cycle arrest, which is similiar to PI-103 treatment alone. Fan, Q., et al. "A dual PI3 kinase/mTOR inhibitor reveals emergent efficacy in glioma." Cancer Cell 9: 341-349 (2006). PI3K inhibitors (PIK-90 and PI-103) enhanced the cytotoxic effects of radiation in PTEN wild type and mutant glioma cells. Chen, J.S., et al. "Characterization of structurally distinct, isoform-selective phosphoinositide 3'-kinase inhibitors in combination with radiation in the treatment of glioblastoma." Mol. Cancer Ther. 7: 841-850 (2008). Our PIK-90 product, whose CAS number appears above, is the free base. The CAS number of the hydrochloride salt is 677338-13-5. Other CAS numbers previously assigned to PIK-90, namely 1029940-40-6 and 1206911-27-4, have been deleted by CAS and are no longer in use. Storage: Store at or below -20 ºC. Solubility: Soluble in DMSO at 0.5 mg/mL with warming; very poorly soluble in ethanol; very poorly soluble in water; maximum solubility in plain water is estimated to be about 20-50 µM buffers, serum, or other additives may increase or decrease the aqueous solubility. Disposal: A
