The subsequent esterification or amidation is conveniently carried out by reacting a corresponding reactive carboxylic acid derivative with a corresponding alcohol or amine as described hereinbefore.
In the reactions described hereinbefore, any reactive groups present such as carboxy, amino, alkylamino or imino groups may be protected during the reaction by conventional protecting groups which are cleaved again after the reaction.
1 For example, a protecting group for a carboxyl group may be a trimethylsilyl, methyl, ethyl, tert.butyl, benzyl 24 or tetrahydropyranyl group and protecting groups for an amino, alkylamino or imino group may be an acetyl, trifluoroacetyl, benzoyl, ethoxycarbonyl, tert.butoxycarbonyl, benzyloxycarbonyl, benzyl, methoxybenzyl or 2,4-dimethoxybenzyl group and additionally, for the amino group, a phthalyl group.

Moreover, chiral compounds of general formula I obtained may be resolved into their enantiomers and/or diastereomers.
Thus, for example, 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 SUS an optically active solvent or by reacting with an 0 6iC 26 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, Nacetylaspartic 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 (-)-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, maleic acid or methanesulphonic acid.
Moreover, if the new compounds of formula I thus obtained contain 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, cyclohexylamine, ethanolamine, diethanolamine and triethanolamine.
27 The compounds of general formulae I to VIII used as starting materials are known from the literature in some cases or may be obtained by methods known from the literature or are described in the Examples.
As already mentioned, the new compounds of general formula I wherein R1 represents a hydrogen atom or a prodrug group have valuable pharmacological properties, particularly inhibitory effects on various kinases and cycline/CDK-complexes, on the proliferation of cultivated human tumour cells and, when administered orally, on the growth of tumours in nude mice infected with human tumour cells.
For example, the compounds listed in Table 1 were tested for their biological properties as follows: Test 1 Inhibition of cycline/CDK enzyme, in vitro activity High FiveTM insect cells (BTI-TN-5Bi_ 4 which had been infected with a high titre of recombinant baculovirus were used to produce active human cycline/CDK holoenzymes. By using a baculovirus vector which contained two promoters (polyhedrin enhancer promoter, enhancer promoter), GST-tagged cyclines (e.g.
cycline D1 or cycline D3) with the corresponding His6tagged CDK subunit for CDK4 or CDK6) were expressed in the same cell. The active holoenzyme was isolated by affinity chromatography on glutathione sepharose. Recombinant GST-tagged pRB (aa 379-928) was produced in E. coli and purified by affinity chromatography on glutathione sepharose.
The substrates used for the kinase assays depended on the specific kinases. Histone H1 (Sigma) was used as 28 the substrate for cycline E/CDK2, cycline A/CDK2, cycline B/CDK1 and for v-cycline/CDK6. GST-tagged pRB (aa 379-928) was used as substrate for cycline D1/CDK4, cycline D3/CDK4, cycline D1/CDK6 and for cycline D3/CDK6.
Lysates of the insect cells infected with recombinant baculovirus or recombinant kinases (obtained from the lysates by purification) were incubated together with radiolabelled ATP in the presence of a suitable substrate with various concentrations of the inhibitor in a 1% DMSO solution (dimethyl sulphoxide) for minutes at 30 0 C. The substrate proteins with associated radioactivity were precipitated with 5% TCA (trichloroacetic acid) in water-repellent PVDF multiwell microtitre plates (Millipore) or with phosphoric acid solution on Whatman P81 filters. After the addition of scintillation liquid the radioactivity was measured in a Wallace 1450 Microbeta Liquid Scintillation Counter. For each concentration of the substance double measurements were carried out; values were calculated for the enzyme inhibition.
Test 2 Inhibition of the proliferation of cultivation human tumour cells Cells of the Leimyosarcoma tumour cell line SK-UT-1B (obtained from the American Type Culture Collection (ATCC)) were cultivated in Minimum Essential Medium with non-essential amino acids (Gibco), supplemented with sodium pyruvate (1 mmol), glutamine (2 mmol) and foetal calf serum (Gibco) and harvested during the loggrowth phase. Then the SK-UT-1B cells were added to Cytostar® multi-well plates (Amersham) at a density of L 4000 cells per well and incubated overnight in an 29 incubator. Various concentrations of the compounds (dissolved in DMSO; final concentration: were added to the cells. After 48 hours' incubation 14C-thymidine (Amersham) was added to each well and incubation was continued for a further 24 hours. The quantity of 14Cthymidine incorporated into the tumour cells in the presence of the inhibitor and representing the number of cells in the S phase was measured in a Wallace 1450 Microbeta Liquid Scintillation Counter. IC50 values for the inhibition of proliferation inhibition of incorporated 14C-thymidine) were calculated, correcting for the background radiation. All the measurements were done twice.
Test 3 In vivo effects on tumour-bearing nude mice 106 cells [SK-UT-1B, or non-small cell lung tumour NCI- H460 (obtained from ATCC)] in a volume of 0.1 ml were injected subcutaneously into male and/or female nude mice (NMRI nu/nu; 25-35g; N 10-20); alternatively, small fragments of SK-UT-1B or NCI-H460 cell clumps were implanted subcutaneously. One to three weeks after the injection or implantation a kinase inhibitor was administered daily by oral route for a period of 2 to 4 weeks (by oesophageal tube). The size of the tumour was measured three times a week using a digital sliding gauge. The effect of a kinase inhibitor on the tumour growth was determined as a percentage inhibition compared with a control group treated with placebo.
