Cat # PKI-SU SU Size: 5.0 mg M.W.= Batch No.: 1A/ Gaither Drive Gaithersburg, MD FAX TEL Web: Description: SU11274 is a ATP-competitive small molecule inhibitor of the catalytic activity of Met which exhibited a selectivity for Met enzyme versus a panel of other tyrosine kinases (Met IC50 = 0.02 µM, Flk IC50 = 1.3, EGFR IC50 = >100 µM, PDGFßR IC50 = >20 µM, Tie2 IC50 = >100 µM, c-src IC50 = >10 µM, cdk2 IC50 = >10 µM, FGFR-1 IC50 = 9.7 µM). Inhibition of the Met kinase activity by SU11274 led to time- and dose-dependent reduced cell growth and induced G1 cell cycle arrest and apoptosis. Physical and Chemical Properties: Molecular Formula: C28H30CIN5O4S Molecular Weight: Physical appearance: orange solid powder Molecular Structure: Solubility: DMSO 10 mg/ml at 60 °C. Stability and Solubility Advice: Some solutions can be difficult to obtain and can be encouraged by rapid stirring, sonication or gentle warming (in a 45-60°C water bath). Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. Our standard recommendations are: SOLIDS: Provided storage is as stated on the product label and the vial is kept tightly sealed, the product can be stored for up to 6 months from date of receipt. SOLUTIONS: We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials at C or below and used within 1 month. Wherever possible solutions should be made up and stored on the same day. This product is for laboratory research ONLY and not for diagnostic use 2006 SignaGen Laboratories References: 1.
