Description

FIELD OF THE INVENTION

The invention relates to 2,4,5-trisubstituted pyrimidines of formula (I)

wherein the groups R_a to R_e have the meanings given in the claims and in the specification, processes for preparing them and the use thereof as pharmaceutical compositions, particularly as pharmaceutical compositions for the treatment of illnesses characterised by excessive or abnormal cell proliferation.

BACKGROUND OF THE INVENTION

International Patent Application WO 00/53595 describes the use of 2,4,5-substituted pyrimidines, with a heterocyclic group in the 4 position and an anilino group in the 2 position, which in turn carries a side chain with the length of at least one n-propyl group, as an active component with an anticancer activity.

Moreover, International Patent Application WO 00/39101 proposes the use of 2,4,5-substituted pyrimidines as compounds with an anticancer activity, which are linked in the 2 and 4 positions to an aromatic or heteroaromatic ring, at least one of which has a side chain with the length of at least one n-propyl group.

Antiviral 2,4,5-substituted pyrimidines, wherein the groups R_c and R_d at the nitrogen of the 4 position form a heteroaromatic five-membered ring, are known from International Patent Application WO 99/41253.

International Patent Application WO 97/19065 also proposes the use of 2,4,5-substituted pyrimidines, with a 3,4-dialkoxy-anilino group in the 2 position, as kinase inhibitors.

For 2,4,5-substituted pyrimidines which carry (hetero)aryls in the 2 and 4 positions (WO00/27825), as well as for 2,4,5-substituted pyrimidines which carry a (hetero)aryl group functionalised with a nitrile group in position 2 or 4 (EPO 945 443), an antiviral activity has been described.

The aim of the present invention is to find new active substances which can be used for the prevention and/or treatment of diseases characterised by excessive or abnormal cell proliferation.

DETAILED DESCRIPTION OF THE INVENTION

Surprisingly, it has now been found that the compounds of general formula (I)

have valuable pharmacological properties, particularly an inhibiting activity on protein kinases such as SRC kinases, PLK kinase and particularly cyclin-dependent kinases (CDKs, such as e.g. CDK1, CDK2, CDK3, CDK4, CDK5, CDK6, CDK7, CDK8 and CDK9 with their specific cyclins A, B1, B2, C, D1 D2, D3, E, F, G1, G2, H, I, K and viral cyclin) as well as on the kinase activity of Aurora B. The compounds exhibit valuable pharmacological properties, such as neuroprotection and an inhibiting activity on the proliferation of cultivated human tumour cells.

In view of their biological properties the new compounds of general formula I, their isomers and their physiologically acceptable salts are suitable for treating diseases characterised by excessive or abnormal cell proliferation.

Such diseases include (with no claim to completeness): viral infections (e.g. HIV and Kaposi's sarcoma); infections caused by adeno, influenza or cytomegaly viruses); bacterial, fungal and/or parasitic infections; skin diseases (e.g. psoriasis, eczema, keratoses); bone diseases; cardiovascular diseases (e.g. restenosis and hypertrophism). They may also be useful in protecting proliferating cells (e.g. hair, intestinal, blood and progenitor cells) against DNA damage caused by radiation, UV treatment and/or cytostatic treatment (Davis et al., 2001, Science, 291, 134-137).

In addition, the compounds are useful for immunosuppression (e.g. in organ transplantation) and for the prevention or treatment of inflammation and autoimmune diseases (e.g. colitis, arthritis, Alzheimer's disease, glomerulonephritis and wound healing).

In particular, these compounds are useful as cytotoxic or cytostatic active substances for the treatment or prevention of diseases based on the proliferation of tumour cells.

The term “cytotoxic compound” denotes a chemical which has a toxic effect on living cells, particularly an active substance which destroys cancer cells. The term “cytostatic compound” denotes a compound which suppresses cell growth and division and thus also suppresses cell proliferation.

Accordingly, in another aspect, the invention relates to the use of a compound of the invention for preparing a pharmaceutical composition for the treatment of cancer. The invention further relates to a method for treating cancer by administering an effective amount of a pharmaceutical composition according to the invention to the patient. The indications include the treatment of cancer, in particular:

• • 1) The treatment of malignant neoplasias and carcinomas including breast cancer, neoplasias of the digestive tract (colorectal carcinoma, anal carcinoma, pancreatic carcinoma, gastric carcinoma, oesophageal carcinoma, hepatocellular carcinoma, gall bladder carcinoma), lung cancer, tumours of the head and neck, ovarian tumours, tumours of the adnexa, endometrial carcinoma, prostate carcinoma, testicular tumours, urothelial carcinoma, kidney cell carcinoma, skin tumours, thyroid carcinoma and endocrinically active tumours.
  • 2) Sarcomas of the bones and soft tissues: osteosarcoma, soft tissue sarcoma, Ewing's sarcoma, chondrosarcoma, fibrosarcoma, malignant fibrous histiocytoma (NFH), leiomyosarcomas and other soft tissue sarcomas;
  • 3) Malignant tumours of haemopoiesis: Hodgkin's and non-Hodgkin's lymphomas; leukaemias, multiple myeloma, myeloproliferative and myelodysplastic syndromes;
  • 4) Neuroectodermal tumours: peripheral nerve sheath tumours, medulloblastomas; neuroblastomas, retinoblastomas, astrocytomas and other brain tumours;
  • 5) Melanomas;
  • 6) Mesotheliomas.

The new compounds of formula I may also be used for the short-term or long-term treatment of the abovementioned diseases, optionally in combination with other “state-of-the-art” compounds such as other cytostatics, antibodies, targeted therapies such as inhibitors of the EGF, Her2 or VEGF signal transduction pathway or angiogenesis inhibitors. The CDK1 inhibitor olomoucine was found to have a synergistic effect with cytotoxic substances in cell culture (Ongkeko et al., 1995, J. Cell Sci., 108, 2897). The compounds mentioned may be administered before or after the administration of known antitumour drugs or cytotoxic substances. It is known that the cytotoxic activity of the CDK inhibitor flavopiridol in conjunction with cancer drugs is influenced by the sequence in which they are administered. (Cancer Research, 1997, 57, 3375).

Examples of cytostatics which are suitable for use in conjunction with the compounds of formula I are anthracycline such as doxorubicin, analogues of methotrexate such as methotrexate, pritrexime, trimetrexate or DDMP, melphalan, analogues of cisplatin such as cisplatin, J216, JM335, bis(platinum), oxaliplatin or carboplatin, analogues of purines and pyrimidines such as cytarabine, gemcitabine, azacitidine, 6-thioguanine, fludarabine or 2-deoxycoformycin and analogues of other chemotherapeutic agents such as 9-amino-camptothecin, D,L-aminoglutethimide, trimethoprim, pyrimethamine, mitomycin C, mitoxantrone, cyclophosphamide, 5-fluorouracil, capecitabine, estramustine, podophyllotoxin, bleomycin, epothilone A, B, C or D and derivatives of epothilone as described for example in U.S. Pat. No. 6,204,388, as well as taxane.

The invention further relates to the physiologically acceptable salts of the compounds of the formula.

The invention also relates to the compounds of formula I for use as pharmaceutical compositions.

In another aspect the invention relates to a process for preparing the compounds of formula I, wherein

a. a compound of general formula

whereinR_c to R_e are as hereinbefore defined andZ₁ denotes a leaving group,is reacted with an amine of general formulaH—(R_aNR_b)  (III)whereinR_a and R_b are as hereinbefore defined; orb. a compound of general formula IV

whereinR_a, R_b and R_e are as hereinbefore defined, andZ₂ denotes a leaving group, is reacted with an amine of general formulaH—(R_cNR_d)  (V)whereinR_c and R_d are as hereinbefore defined.

The reaction is expediently carried out in a solvent such as ethanol, isopropanol, butanol, tetrahydrofuran, dioxan, toluene, chlorobenzene, dimethylformamide, dimethylsulphoxide, ethylenglycolmonomethylether, ethylenglycoldiethylether or sulpholane optionally in the presence of an inorganic base, e.g. sodium carbonate or potassium hydroxide, or a tertiary organic base, e.g. triethylamine, N-ethyl-diisopropylamine or pyridine, while the latter may simultaneously also act as solvent, and optionally in the presence of a reaction accelerator such as a copper salt, a corresponding amine-hydrohalide or alkali metal halide at temperatures between 0 and 250° C., preferably however at temperatures between 20 and 200° C. The reaction may however also be carried out without a solvent or in an excess of the compound of formula III or V used.

Moreover the compounds of general formula I obtained as mentioned hereinbefore may be resolved into their enantiomers and/or diastereomers. Thus, for example, cis-/trans mixtures may be resolved into their cis- and trans-isomers, and compounds with at least one optically active carbon atom are resolved into their enantiomers.

Thus, for example, the cis/trans mixtures obtained may be resolved by chromatography into the cis and trans isomers thereof, the compounds of general formula I obtained which occur as racemates may be separated by methods known per se (cf. Allinger N. L. and Eliel E. L. in “Topics in Stereochemistry”, Vol. 6, Wiley Interscience, 1971) into their optical antipodes and compounds of general formula I with at least 2 asymmetric carbon atoms may be resolved into their diastereomers on the basis of their physical-chemical differences using methods known per se, e.g. by chromatography and/or fractional crystallisation, and, if these compounds are obtained in racemic form, they may subsequently be resolved into the enantiomers as mentioned above.

The enantiomers are preferably separated by column separation on chiral phases or by recrystallisation from an optically active solvent or by reacting with an optically active substance which forms salts or derivatives such as e.g. esters or amides with the racemic compound, particularly acids and the activated derivatives or alcohols thereof, and separating the diastereomeric mixture of salts or derivatives thus obtained, e.g. on the basis of their differences in solubility, whilst the free antipodes may be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Optically active acids in common use are e.g. the D- and L-forms of tartaric acid or dibenzoyltartaric acid, di-o-tolyltartaric acid, malic acid, mandelic acid, camphorsulphonic acid, glutamic acid, N-acetylglutamic acid, aspartic acid, N-acetylaspartic acid or quinic acid. An optically active alcohol may be for example (+)- or (−)-menthol and an optically active acyl group in amides, for example, may be a (+)- or (−)-menthyloxycarbonyl group.

Furthermore, the compounds of formula I obtained may be converted into the salts thereof, particularly for pharmaceutical use into the physiologically acceptable salts with inorganic or organic acids. Acids which may be used for this purpose include for example hydrochloric acid, hydrobromic acid, sulphuric acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid.

Moreover, if the new compounds of formula I thus obtained contain an acid group such as a carboxy group, they may subsequently, if desired, be converted into the salts thereof, with inorganic or organic bases, particularly for pharmaceutical use into the physiologically acceptable salts thereof. Suitable bases for this purpose include for example sodium hydroxide, potassium hydroxide, arginine, cyclohexylamine, ethanolamine, diethanolamine and triethanolamine.

The compounds of general formulae II to V used as starting materials are known from the literature in some cases or may be obtained by methods known from the literature.

As already mentioned, the compounds of formula I according to the invention and the physiologically acceptable salts thereof have valuable pharmacological properties, particularly an inhibitory effect on the proliferation of cells, particularly endothelial cells. This effect of the new compounds was tested by the following standard procedure, as follows:

The invention also relates to the use of compounds of formula (I) for preparing a medicament for the treatment and prevention of diseases characterised by excessive or anomalous cell proliferation, as well as pharmaceutical compositions which are characterised by a content of one or more compounds of formula I.

Some procedures for preparing the compounds according to the invention will be described in detail hereinafter by way of example. The following Examples of synthesis are intended solely as a detailed illustration without restricting the object of the invention thereto.

Preparation of Recombinant Cyclin-CDK Enzymes

The corresponding cDNAs for human cyclin B1 (cyclin E, or. cyclin D1) and human CDK1 (CDK2, or. CDK4) were cloned by standard methods using RT-PCR, and cloned into a transfer vector (cyclin in pAcG2T made by Pharmingen, CDKs in p2Bac made by Invitrogen) for the baculovirus system. Recombinant cyclin B1-CDK1 (or cyclin E-CDK2, cyclin D1-CDK4) was expressed in High Five insect cells (Trichoplusia ni) by coinfection with both recombinant baculoviruses (after the 4th round of amplification, >1×10⁸ viruses/ml). 72 h after the infection the High Five cells were harvested, and deep-frozen in liquid nitrogen. After thawing the cells were resuspended in lysing buffer (50 mM HEPES pH 7.5, 10 mM MgCl₂, 1 mM DTT, 5 μg/ml leupeptin, 5 μg/ml aprotinin, 100 μM NaF, 100 μM PMSF, 10 mM β-glycerolphosphate, 100 μM Na₃VO₄, 30 mM nitrophenylphosphate, 17.5 ml of lysing buffer per 10⁸ cells) and incubated on ice for 30 min. The cell lysate was freed from the cell debris by centrifugation and the quantity of recombinant cyclin B1-CDK1 enzyme (or cyclin E-CDK2, cyclin D1-CDK4) in the total lysate (about 1-5 mg/ml) was determined by SDS-polyacrylamide gel electrophoresis. Cyclin D1-CDK4 was purified by means of a GST-tag on cyclin D1 and then using glutathione beads (total protein about 0.2 mg/ml).

Example 13

Cyclin B1-CDK1 Kinase Inhibition Test

All the kinase tests were carried out in 96-well microtitre plates (Greiner PS) in a final volume of 60 μl. The kinase test contained 1% DMSO (v/v), 5 μg of histone H1 (calf thymus, Roche Molecular Biochemicals), 1 to 5 μg of a cell lysate with recombinant cyclin B1/CDK1, the test substance (in a final concentration of 1 nM to 10 μM) and kinase buffer (15 mM MgCl₂, 25 mM MOPS, pH 7.0, 0.1 mM DTT). As a negative control the kinase reaction was carried out in the absence of the substrate histone H1. As a positive control the kinase reaction was carried out in the absence of a test substance. As an internal control 30 μM and 300 μM (final concentration) of the kinase inhibitor olomoucin (Alexis) were used.

The PS microtitre plates were placed on ice, and 10 μl of the test substance, in different concentrations (in each case in 6% DMSO), 20 μl of the histone H1 (250 μg/ml in kinase buffer) and 20 μl of cyclin B1/CDK1 (1 to 5 μg of the recombinant cell lysate in 20 μl of kinase buffer) were pipetted in and mixed together. The kinase reaction is started by the addition of 10 μl of ATP mix (0.045 mM ATP, 0.5 μCi ³³P-ATP in kinase buffer) and incubated for 30 min at 30° C. and 600 rpm in a shaking incubator. After incubation the plates were placed on ice and the proteins were precipitated by the addition of 125 μl of ice-cold 5% trichloroacetic acid. After 15 min on ice the precipitates were transferred onto Packard Unifilter 96 GF/B plates with the Packard Harvester System, and collected by vacuum filtration. The precipitates were washed 4 times with dist. H₂O at ambient temperature. The filter plates were then dried at 60° C. and 50 μl of scintillation liquid were added to each well (Ultima Gold, Packard). The plate was sealed up with Sealing Tape and after 1 h measured in a scintillation measuring apparatus (Micro Beta made by Wallac).

The inhibition of the substances was calculated as a percentage of the control (cyclin B1-CDK1 without inhibitor) and the active substance concentration which inhibits the enzyme activity by 50% (IC50) was derived.

Example 14

Cyclin E-CDK2 Kinase Inhibition Test

The inhibition test with cyclin E-CDK2 was carried out using the same method as for cyclin B1-CDK1, except that recombinant cyclin E-CDK2 was used as the enzyme.

Example 15

Cyclin D1-CDK4 Kinase Inhibition Test

For the inhibition test with cyclin D1-CDK4, recombinant Retinoblastoma Protein (pRB) from aa379-928, which contains a GST-tag at the N-terminus, was used as the substrate. GST-pRB was expressed in bacteria and then purified using glutathione beads (about 0.2 mg/ml).

The kinase test contained 1% DMSO (v/v), 10 μg pRB, 0.4 μg of a cell lysate with recombinant cyclin D1-CDK4, the test substance (final concentration from 1 nM to 10 μM) and kinase buffer (15 mM MgCl₂, 25 mM MOPS, pH 7.0, 0.1 mM DTT). As a negative control the kinase reaction was carried out in the absence of the substrate pRB. As a positive control the kinase reaction was carried out in the absence of a test substance. As an internal control 30 μM and 300 μM (final concentration) of the kinase inhibitor olomoucin (Alexis) were used.

The PS microtitre plates were placed on ice, and 10 μl of the test substance, in different concentrations (in each case in 6% DMSO), 20 μl of pRB (10 μg in kinase buffer) and 20 μl of cyclin D1-CDK4 (0.4 μg of the recombinant cell lysate in 20 μl of kinase buffer) were pipetted in and mixed together. The kinase reaction was started by the addition of 10 μl of ATP mix (0.045 mM ATP, 1 μCi ³³P-ATP in kinase buffer) and incubated for 45 min at 32° C. and 600 rpm in a vibrating incubator. After incubation, 50 μl of the reaction mixture were pipetted onto P81 filters (Whatmann). After 20 sec reaction time the filters were washed 4 times with 1.5% phosphoric acid (about 5 min per washing step) while shaking them gently. After washing the filters were dried at 85° C., scintillation liquid was added and the scintillation was measured in a scintillation counter (Micro Beta made by Wallac).

Measurement of the Cytotoxicity on Cultivated Human Tumour Cells

Cells of the non-small cell lung tumour cell line NCI H-460 (obtained from American Type Culture Collection (ATCC)) were cultivated in RPMI1640 medium (Gibco) and 10% foetal calf serum (Gibco) and harvested in the log growth phase. Then the NCI H-460 cells were placed in 96-well plates (Costar) at a density of 1000 cells per well and incubated overnight in an incubator (at 37° C. and 5% CO₂), each plate containing 6 wells which were filled only with medium (3 wells as a medium control and 3 wells for incubation with reduced AlamarBlue). The active substances were added to the cells in various concentrations (dissolved in DMSO; final concentration: 1%) (each measurement being done three times). After 72 hours incubation 20 μl AlamarBlue (AccuMed International) were added to each well, and the cells were incubated for a further 5 hours. As a control 20 μl of reduced Alamar Blue were added to three wells (AlamarBlue Reagent autoclaved for 30 min) After 5 h incubation the colour change of the AlamarBlue Reagent in the individual wells was determined in an Perkin Elmer Fluorescence spectrophotometer (excitation 530 nm, emission 590 nm, slits 15, integrate time 0.1). The quantity of AlamarBlue Reagent reacted represents the metabolic activity of the cells. The relative cell activity was calculated as a percentage of the control (NCI H-460 cells without an inhibitor) and the active substance concentration which inhibits the cell activity by 50% (IC50) was derived. The values were calculated from the average of three separate measurements, correcting for the control value (medium control).
