  • the amount of incorporated 33 P (substrate phosphorylation) was determined by scintillation measurement in a gamma radiation meter (Wallac).
  • the data were normalized to 0% inhibition (enzyme reaction without inhibitor) and 100% inhibition (all assay components except enzyme).
  • the IC50 values were determined using a 4-parameter fit using proprietary
  • Cultured human MCF7 breast tumor cells (ATCC HTB-22) were incubated at a density of 5000 cells / measurement point in a 96-well multititer plate in 200 ⁇ l growth medium (RPMM 640, 10% fetal calf serum, 2 mU / ml insulin, 0.1 nM estradiol). plated. After 24 hours, the cells of one plate (zero plate) were stained with crystal violet (see below), while the medium of the other plates was replaced by fresh culture medium (200 ⁇ l) containing the test substances at various concentrations (0 ⁇ M and in the range 0.01 - 30 ⁇ M, the final concentration of the solvent dimethylsulfoxide was 0.5%) were added replaced.
  • the cells were incubated for 4 days in the presence of the test substances. Cell proliferation was determined by staining the cells with crystal violet.
  • the cells were fixed by adding 20 ⁇ l / measuring point of an 11% glutaraldehyde solution for 15 minutes at room temperature. After washing the fixed cells three times with water, the plates were dried at room temperature.
  • the cells were stained by adding 100 ⁇ l / measuring point of a 0.1% crystal violet solution (pH adjusted to pH 3 by addition of acetic acid). After washing the stained cells three times with water, the plates were dried at room temperature.
  • the dye was dissolved by adding 100 ⁇ l / measuring point of a 10% acetic acid solution and the absorbance was determined photometrically at a wavelength of 595 nm.
  • the IC50 values were determined using a 4-parameter fit using proprietary software.
  • Example 1 to 22 were tested for their inhibitory effect in the various kinase assays as well as in a proliferation assay with MCF7 human breast tumor cells (Table 1).
  • the data demonstrate that the example compounds act as potent, nanomolar protein kinase inhibitors.
  • selectivity profiles can be adjusted (Examples 9, 15, 17: CDK-selective, Example 16: preferential KDR inhibition).
  • Example compounds 1-8, 10-12, 15, 17-20 inhibit the proliferation of human MCF7 breast tumor cells at half-maximal concentrations in the sub-micromolar range.
