  • WGA- purified rat liver InsRK (1.25 ⁇ g) is preincubated with or without 330 nM insulin in 50 mmol Tris-Mes buffer, pH 7.6, for 30 minutes at 22°C. The assay is performed at 22°C and
  • the total volume of the assay is 40 ⁇ l. After 20 minutes, aliquots of 30 ⁇ l are applied on Whatman 3-mm paper and soaked in cold 10% TCA, containing 0.01 M sodium pyrophosphate.
  • A431 cells were grown to confluence on human fibronectin coated tissue culture dishes. After washing 2 times with icecold PBS, cells were lysed by the addition of 500 ⁇ l/dish of lysis buffer (50 mmol Hepes, pH 7.5, 150 mmol NaCl, 1.5 mmol MgCl 2 , 1 mmol EGTA, 10% glycerol, 1% triton X-100, 1 mmol PMSF, l mg/ml aprotinin, 1 mg/ml leupeptin) and incubating 5 minutes at 4°C.
  • lysis buffer 50 mmol Hepes, pH 7.5, 150 mmol NaCl, 1.5 mmol MgCl 2 , 1 mmol EGTA, 10% glycerol, 1% triton X-100, 1 mmol PMSF, l mg/ml aprotinin, 1 mg/ml leupeptin
  • IC 50 refers to the concentration of inhibitor ( ⁇ M) at which the rate of autophosphorylation is halved, compared with media containing no inhibitor.
  • IC 50 values for EGF will be lower than for PDGF, indicating a high degree of EGF
  • Cells were seeded at 1 x 10 5 cells per well in 24-well Costar dishes pre-coated with human fibronectin (by incubating for 30 minutes at room temperature with 10 ⁇ g/0.5 ml/well). The cells were grown to confluence for 2 days. The medium was changed to DMEM containing 0.5 calf serum for 36-48 hours and the cells were then incubated with PDGF, EGF (Toyobo, New York, NY) (20 ng/ml) or serum (10% calf serum, FCS) and different concentrations of the inhibitory compounds.
  • PDGF fetal growth factor
  • EGF Toyobo, New York, NY
  • serum 10% calf serum, FCS
  • IC 50 refers to the concentration of inhibitor (nM) at which
  • [ 3 H]thymidine incorporation is halved, compared with media containing no inhibitor.
  • FCS contains a broad range of growth factors
  • the IC 50 values for PDGF should be lower than for FCS, indicating that the compounds do not act as general inhibitors.
  • HER 14 and K721A were prepared by transfecting N1H3T3 cells (clone 2.2) (From C. Fryling, NCI, NIH), which lack endogenous EGF-receptors, with cDNA
  • Example 1A is a more potent inhibitor of EGF receptor kinase than C-1.
  • Example 1-A it can be seen from the test results that it has also a much better activity than that of its corresponding N-oxide.
