FIELD OF THE INVENTION
This invention pertains to compounds that inhibit protein kinases, compositions containing the compounds and methods of treating diseases using the compounds.
BACKGROUND OF THE INVENTION
Numerous human diseases are characterized by increased and uncontrolled cell growth. This biology is driven, in many cases, by increased growth factor signaling. In addition, these pathologies often require an expanding blood supply and new vessel growth. Protein kinases are key components of both cell proliferation and endothelial cell expansion. Kinases are thus important targets for therapeutic intervention in pathologies characterized by uncontrolled cell growth.

To determine the binding of compounds having Formula I to a representative protein kinase, protein tyrosine kinase, the following assay was used:
Homogenous time-resolved fluorescence (HTRF) in vitro kinase assays were used to detect and measure the inhibition of kinase activity. The HTRF assays were conducted as described in Mathis, G., HTRF(R) Technology. J Biomol. Screen, 1999. 4(6): pp. 309-314). The protocol was adapted for determining activity with respect to a specific protein tyrosine kinase (PTK). A preferred protocol for conducting the HTRF experiments is described hereinbelow. Adaptation of these protocols for determining a compound's activity for other kinases are well within the abilities of the skilled practioner.
In a representative experiment, 10 μL of KDR, prepared as described herein, was mixed with 10 μL of inhibitor (various concentrations, 2% final DMSO) and 10 μL of ATP (125 μM final concentration) in reaction buffer (50 mM HEPES, pH 7.5, 10 mM MgCl2, 2 mM MnCl2, 0.1% BSA and 1 mM DTT, 40 μL final volume). The reaction was initiated by addition of Bio-fgfr peptide (Genemed Biotechnologies, Inc., San Francisco, Calif.), 0.5 μM final concentration) in a black 96-well plate (Packard). After 45 minutes incubation at room temperature, the reaction was quenched by adding 60 μL of stop/revelation buffer to give 30 mM EDTA, 1 μg/mL streptavidin-APC (Prozyme), 50 ng/mL anti-phosphotyrosine mAb PT66-K Europium Cryptate, 30 mM HEPES, pH 7.5, 120 mM KF, 0.005% Tween-20, 0.05% BSA). The quenched reaction stood at room temperature for 1 hour and then read in a time-resolved fluorescence detector (Envision, Perkin Elmer) at 615 nm and 665 nm, simultaneously. The ratio between the signal of 615 nm and 665 nm was used in the calculation of the IC50's. Ki values were calculated as described in Biochem. Pharmacol. 1973, 22, 3099-3108.
The coding sequence for the human KDR intra-cellular domain (aa789-1354) was generated through PCR using cDNAs isolated from HUVEC cells. A poly-His6 sequence was also introduced at the N-terminus of this protein. This fragment was cloned into transfection vector pVL1393 at the Xba 1 and Not 1 site. Recombinant baculovirus (BV) was generated through co-transfection using the BaculoGold Transfection reagent (PharMingen). Recombinant BV was plaque purified and verified through Western analysis. For protein production, SF-9 cells were grown in SF-900-II medium at 2×106/mL, and were infected at 0.5 plaque forming units per cell (MOI). Cells were harvested at 48 hours post infection.
SF-9 cells expressing (His)6 KDR(aa789-1354) were lysed by adding 50 mL of Triton X-100 lysis buffer (20 mM Tris, pH 8.0, 137 mM NaCl, 10% glycerol, 1% Triton X-100, 1 mM PMSF, 10 μg/mL aprotinin, 1 μg/mL leupeptin) to the cell pellet from IL of cell culture. The lysate was centrifuged at 19,000 rpm in a Sorval SS-34 rotor for 30 min at 4° C. The cell lysate was applied to a 5 ml NiCl2 chelating sepharose column, equilibrated with 50 mM HEPES, pH7.5, 0.3 M NaCl. KDR was eluted using the same buffer containing 0.25 M imidazole. Column fractions were analyzed using SDS-PAGE and an ELISA assay (below) which measures kinase activity. The purified KDR was exchanged into 25 mM HEPES, pH7.5, 25 mM NaCl, 5 mM DTT buffer and stored at −80° C. Results are shown in TABLES 1 and 2.

Homogenous time-resolved fluorescence (HTRF) in vitro kinase assays were also sed to measure inhibition of kinase activity. The HTRF assays were conducted according to known protocols (Technology. J. Biomol. Screen, 1999, 4(6): pp 309-314).
The protocol was adapted for determining activity with respect to a specific PTK. For example, a preferred protocol for conducting the HTRF experiments is provided below. Adaptation of these protocols for determination of a compound's activity for other kinases are well within the abilities of the skilled practioner.
In a representative experiment, 10 μL KDR, prepared as described herein, was mixed with 10 μL inhibitor (various concentrations, 2% final DMSO) and 10 μL of ATP (125 μM final concentration) in reaction buffer (50 mM HEPES, pH 7.5, 10 mM MgCl2, 2 mM MnCl2, 0.1% BSA and 1 mM DTT; final volume: 40 μL). The reaction was initiated by adding Bio-fgfr peptide (purchased from Genemed Biotechnologies Inc., San Francisco, Calif., 0.5 M final concentration) in a black 96-well plate (Packard). After 45 minutes incubation at room temperature, the reaction was quenched by adding 60 μL stop/revelation buffer to give 30 mM EDTA, 1 μg/mL Streptavidin-APC (Prozyme), 50 ng/mL anti-phosphotyrosine mAb PT66-K Europium Cryptate, 30 mM HEPES, pH 7.5, 120 mM KF, 0.005% Tween-20, 0.05% BSA). The quenched reaction stood at room temperature for 1 hour and was read in a time-resolved fluorescence detector (Envision, Perkin Elmer) at 615 nm and 665 nm to calculate the IC50. Ki values were calculated as described in Biochem. Pharmacol. 1973, 22, 3099-3108.
Related procedures were used to assay the inhibitory effect of compounds of this invention on c-Kit, IGF-IR, EGFR, Src and ErbB2 tyrosine kinase activity.
The coding sequence for human KDR intra-cellular domain (aa789-1354) was generated through PCR using cDNAs isolated from HUVEC cells. A poly-His6 sequence was introduced at the N-terminus of this protein, as well. This fragment was cloned into transfection vector pVL1393 at the Xba 1 and Not 1 site. Recombinant baculovirus (BV) was generated through co-transfection using the BaculoGold Transfection reagent (PharMingen). Recombinant BV was plaque purified and verified through western analysis. For protein production, SF-9 cells were grown in SF-900-II medium at 2×106/mL, and were infected at 0.5 plaque forming units per cell (MOI). Cells were harvested at 48 hours post infection.
SF-9 cells expressing (His)6 KDR (aa789-1354) were lysed by adding 50 ml of Triton X-100 lysis buffer (20 mM Tris, pH 8.0, 137 mM NaCl, 10% glycerol, 1% Triton X-100, 1 mM PMSF, 10 μ/mL aprotinin, 1 μg/mL leupeptin) to the cell pellet from IL of cell culture. The lysate was centrifuged at 19,000 rpm in a Sorval SS-34 rotor for 30 minutes a 4° C. The cell lysate was applied to a 5 mL NiCl2 chelating sepharose column equilibrated with 50 mM HEPES, pH 7.5 and 0.3 M NaCl. KDR was eluted using the same buffer containing 0.25 M imidazole. Column fractions were analyzed using SDS-PAGE and ELISA assay, which measures kinase activity. The purified KDR was exchanged into 25 mM HEPES, pH 7.5, 25 mM NaCl and 5 mM DTT buffer and stored at −80° C.
The data from these assays demonstrate the utility of compounds having Formula I as protein kinase inhibitors and are therefore expected to have utility in treatment of diseases during which any kinase family member is expressed.
