Description

Sulfonamido-Macrocycles and the Salts thereof, A Pharmaceutical Composition Comprising These Compounds, the Method of Preparing and the Use Thereof

The invention relates to sulfonamido-macrocycles and the salts thereof, to pharmaceutical compositions comprising the sulfonamido-macrocycles and to methods of preparing the sulfonamido-macrocycles as well as to the use thereof.

In order to defeat diseases with dysregulated vascular growth such as cancer different strategies were developed. One possible strategy is the blockade of angiogenesis to the tumour tissue, because tumour angiogenesis is a prerequisite for the growth of solid tumours.

The angiogenesis represents beside the vasculogenesis one of two basic processes during the genesis of vasculature. Vasculogenesis names the neoplasm of vasculature during the embryo development, wherein the angiogenesis describes the neoplasm of vasculature by sprouts or division of present vasculature. It has been found that two receptors expressed on endothelial cells, VEGF- (vascular endothelial growth factor) and Tie- receptors, are essential for normal development of vascular tissue as blood vessels (Dumont et at., (1994). Dominant-negative and targeted null mutations in the endothelial receptor tyrosine kinase Tie2 (also named tek) reveal a critical role in vasculogenesis of the embryo. Genes Dev, 8:1897-909; Sato et α/.: "Distinct roles of the receptor tyrosine kinases Tie-1 and Tie-2 in blood vessel formation" Nature. 1995, JuI 6; 376(6535):70-4.).

The mechanism of Tie2 signalling was characterized by different researchers, wherein different angiopoietins were found to be involved. So it could be explained that angiopoietin-1 if bound to the extracellular domain of the Tie2-receptor stimulates autophosphorylation and activates the intracellular kinase domain. Angiopoietin-1 activation of Tie2 however does not stimulate mitogenesis but rather migration. Angiopoietin-2 can block angiopoietin-1 mediated Tie2 activation and the resulting endothelial migration. This indicates that angiopoietin-2 is a naturally occurring inhibitor of Tie2 activation (Maisonpierre et al. \ "Angiopoietin-2, a natural antagonist for Tie2 that disrupts in vivo angiogenesis". Science. 1997, JuI 4; 277(5322):55-60; Witzenbichler et al.\ ,,Chemotactic properties of angiopoietin-1 and -2, ligands for the endothelial-specific receptor tyrosine kinase Tie2". J Biol Chem. 1998, JuI 17; 273(29): 18514-21 ). For an overview see Figure 1 modified by Peters et al. (Peters et al. : "Functional significance of Tie2 signalling in the adult vasculature". Recent Prog Horm Res. 2004; 59:51 -71. Review.).

Receptor dimerization results in cross-phosphorylation on specific tyrosine- residues. Receptor cross-phosphorylation has a dual effect: it enhances the receptor's kinase activity and it provides binding sites for signalling molecules possessing phosphotyrosine binding domains (SH2 and PTB domains) (Pawson T.: "Regulation and targets of receptor tyrosine kinases". Eur J Cancer. 2002, Sep, 38 Suppl 5:53-10. Review).

The signalling cross-talk between the PI3-K pathway and the Dok-R pathway is required for an optimal chemotactic response downstream of Tie2. Other recent studies have shown that Tie2-mediated activation of the PI3-K/Akt pathway is required for endothelial nitric oxide synthase (eNOS) activation, focal adhesion kinase activation, and protease secretion, all of which may contribute importantly to Tie2 function during angiogenesis (Kim I. et al.: "Angiopoietin-1 regulates endothelial cell survival through the phosphatidylinositol 3'-Kinase/Akt signal transduction pathway". Circ Res.

2000, Jan 7-21 ; 86(1 ):24-9; Babaei et al. : "Angiogenic actions of angiopoietin-1 require endothelium-derived nitric oxide". Am J Pathol. 2003,

Jun; 162(6):1927-36).

For normal development a balanced interaction between the receptors and so-called ligands is necessary. Especially the angiopoietins, which signal via Tie2 receptors, play an important role in angiogenesis (Babaei et al., 2003). The broad expression of Tie2 in adult vasculature has been confirmed in transgenic mice using Tie2 promoter driven reporters (Schlaeger et al. : "Uniform vascular-endothelial-cell-specific gene expression in both embryonic and adult transgenic mice". Proc Natl Acad Sci U S A. 1997, Apr 1 ; 94(7):3058-63; Motoike et at. : "Universal GFP reporter for the study of vascular development". Genesis. 2000, Oct; 28(2):75-81 ). lmmunohistochemical analysis demonstrated the expression of Tie2 in adult rat tissues undergoing angiogenesis. During ovarian folliculogenesis, Tie2 was expressed in the neo-vessels of the developing corpus luteum. Angiopoietin-1 and angiopoietin-2 also were expressed in the corpus luteum, with angiopoietin-2 localizing to the leading edge of proliferating vessels and angiopoietin-1 localizing diffusely behind the leading edge (Maisonpierre et al., 1997). It was suggested that angiopoietin-2-mediated inhibition of Tie2 activation serves to "destabilize" the vessel, to make it responsive to other angiogenic growth factors such as VEGF. Subsequently, angiopoietin-1 - mediated activation of Tie2 would trigger stabilization of the neovasculature.

The disruption of Tie2 function shows the relevance of Tie2 for neoangiogenesis in transgenic mice resulting in early embryonic lethality as a consequence of vascular abnormalities (Dumont et al. , 1994; Sato et al., 1995). Tie2-/- embryos failed to develop the normal vessel hierarchy, suggestive of a failure of vascular branching and differentiation. Tie2-/- embryos have a decreased number of endothelial cells and furthermore less contact between endothelial cells and the underlying pericytes/smooth muscle cells. This implies a role in the maturation and stabilization of newly formed vasculature.

The studies in mice with transgenic or ablated Tie2 gene suggest a critical role for Tie2 in maturation of vascular development in embryos and in adult vasculature. Conditional expression of Tie2 in the endothelium of mice homozygous for a Tie2 null allele partially rescued the embryonic lethality of the Tie2 null phenotype (Jones N et al. : "Tie receptors: new modulators of angiogenic and lymphangiogenic responses." Nat Rev MoI Cell Biol. 2001 Apr; 2(4):257-67. Review). Mice lacking functional angiopoietin-1 expression and mice over-expressing angiopoietin-2 both displayed a phenotype similar to Tie2-/- mice (Suri et α/.: "Requisite role of angiopoietin-1 , a ligand for the Tie2 receptor, during embryonic angiogenesis." Ce//. 1996 Dec 27; 87(7): 1171 -80; Maisonpierre PC et α/.: "Angiopoietin-2, a natural antagonist for Tie2 that disrupts in vivo angiogenesis. Science. 1997 JuI 4; 277(5322):55-60.).

Angiopoietin-2 -/- mice have profound defects in the growth and patterning of lymphatic vasculature and fail to remodel and regress the hyaloid vasculature of the neonatal lens (Gale et α/. : "Angiopoietin 2 is required for postnatal angiogenesis and lymphatic patterning, and only the latter role is rescued by Angiopoietin-1 ". Dev Cell. 2002, Sep; 3(3):411 -23). Angiopoietin-1 rescued the lymphatic defects, but not the vascular remodelling defects. So angiopoietin-2 might function as a Tie2 antagonist in blood vasculature but as a Tie2 agonist in developing lymph vasculature.

Tie2 also plays a role in pathological angiogenesis. It was shown that mutations in Tie2 cause inherited venous malformations and enhance both ligand dependent and independent Tie2 kinase activity (Vikkula et α/. : "Dysmorphogenesis caused by an activating mutation in the receptor tyrosine kinase Tie2". Ce//. 1996, Dec 27; 87(7): 1181 -90). Tie2 expression was investigated in human breast cancer tumour specimens and Tie2 expression was found in the vascular endothelium both in normal breast tissue and in breast tumours. The proportion of Tie2-positive tumour microvessels was increased in tumours as compared to normal breast tissue (Peters KG et o/. : "Expression of Tie2/Tek in breast tumour vasculature provides a new marker for evaluation of tumour angiogenesis. Br J Cancer. 1998, 77(1 ):51 -6).

Angiopoietin-1 overexpression in tumour models resulted in decreased tumour growth. The effect is possibly related to angiopoietin-1 mediated stabilization of the tumour vasculature, which renders the vessels resistant to angiogenic stimuli (Hayes et α/. : "Expression and function of angiopoietin-1 in breast cancer". Br J Cancer. 2000, Nov; 83(9):1154-60; Shim et α/. : "Inhibition of angiopoietin-1 expression in tumour cells by an antisense RNA approach inhibited xenograft tumour growth in immunodeficient mice", lnt J Cancer. 2001 , Oct 1 ; 94(1 ):6-15; Shim et al. : "Angiopoietin 1 promotes tumour angiogenesis and tumour vessel plasticity of human cervical cancer in mice". Exp Cell Res. 2002, Oct 1; 279(2):299-309; Hawighorst et al. : "Activation of the Tie2 receptor by angiopoietin-1 enhances tumour vessel maturation and impairs squamous cell carcinoma growth". Am J Pathol. 2002, Apr;160(4):1381 -92.; Stoeltzing et al. \ "Angiopoietin-1 inhibits vascular permeability, angiogenesis, and growth of hepatic colon cancer tumours". Cancer Res. 2003, Jun 15; 63(12):3370-7.).

Corneal angiogenesis induced by tumour cell conditioned medium was inhibited by recombinant sTie, despite the presence of VEGF. Mammary tumour growth was significantly inhibited in a skin chamber tumour model by recombinant sTie2 (Lin et al. : "Inhibition of tumour angiogenesis using a soluble receptor establishes a role for Tie2 in pathologic vascular growth". J Clin Invest. 1997, Oct 15;100(8):2072-8; Lin et al. : "Antiangiogenic gene therapy targeting the endothelium-specific receptor tyrosine kinase Tie2". Proc Natl Acad Sci U S A. 1998, JuI 21 ; 95(15):8829-34). Similar sTie constructs have shown comparable effects in different tumour models (Siemeister et al. : "Two independent mechanisms essential for tumour angiogenesis: inhibition of human melanoma xenograft growth by interfering with either the vascular endothelial growth factor receptor pathway or the Tie-2 pathway". Cancer Res. 1999, JuI 1 ; 59(13):3185-91 ; Stratmann et al.: "Differential inhibition of tumour angiogenesis by Tie2 and vascular endothelial growth factor receptor-2 dominant-negative receptor mutants". lnt J Cancer. 2001 , Feb 1 ; 91 (3):273-82; Tanaka et al. : "Tie2 vascular endothelial receptor expression and function in hepatocellular carcinoma". Hepatology. 2002, Apr; 35(4):861 -7).

When the interaction of angiopoietin -2 with its receptor is blocked by application of a neutralizing anti-angiopoietin-2 monoclonal antibody, the growth of experimental tumours can be blocked efficiently again pointing to the important role of Tie2 in tumour angiogenesis and growth (Oliner et al. : "Suppression of angiogenesis and tumour growth by selective inhibition of angiopoietin-2". Cancer Cell. 2004, Nov; 6(5):507-16.) So inhibiting the Tie2 pathway will inhibit pathological angiogenesis.

To influence the interaction between receptor and ligand it could be shown that angiogenesis may be blocked with blockers such as Avastin which interfere with VEGF signal transduction to endothelial cells.

Avastin is a clinically effective antibody that functions as tumour growth inhibitor by blockade of VEGFR mediated angiogenic signalling. Thus interference with VEGF signalling is a proven clinical principle. VEGF-C is a molecule inducing lymph angiogenesis via VEGFR 3. The blockade of this signal pathway is inhibiting diseases associated with lymph angiogenesis as is lymphedema and related diseases (Saharinen et al.: "Lymphatic vasculature: development, molecular regulation and role in tumour metastasis and inflammation." Trends Immunol. 2004, Jul:25(7): 387-95. Review).

Pyrimidines and their derivatives have been frequently described as therapeutic agents for diverse diseases. A series of recently published patent applications describes their use as inhibitors of various protein kinases, for example WO 2003/032994 A, WO 2003/063794 A, and WO 2002/096888 A. More specifically, certain pyrimidine derivatives have been disclosed as inhibitors of protein kinases involved in angiogenesis, such as VEGF or Tie2, for example benzimidazole substituted 2,4-diaminopyrimidines (WO 2003/074515 A) or (bis)anilino-pyrimidines (WO 2003/066601 A). Very recently, pyrimidine derivatives in which the pyrimidine constitutes a part of a macrocyclic ring system have been reported to be inhibitors of CDKs and/or VEGF (WO 2004/026881 A), or of CDK2 and/or CDK5, respectively (WO 2004/078682 A).

A particular problem in using such known substances as inhibitors or blockers is that their use at the same time is often accompanied with undesired cytotoxic side effects on normal developing and proliferating tissue. This originates from substances which are less selective and at the same time dose tolerability problems. Therefore the aim of the present invention is to provide compounds, which are useful for the treatment of diseases of dysregulated vascular growth or diseases which are accompanied by dysregulated vascular growth. Furthermore the prior art problems shall be prevented, especially compounds shall be provided, which show low toxic side effects on normal proliferating tissue but are effectively inhibiting endothelial cell migration at small concentrations. This will further reduce undesired side effects.

The solution to the above problems is achieved by providing compounds derived from a class of sulfonamido-macrocycles and the salts thereof, methods of preparing sulfonamido-macrocycles, a pharmaceutical composition containing said sulfonamido-macrocycles, use of said compounds as a medicament, and a method for treating diseases with said compounds, all in accordance with the description, and as defined in the claims, of the present Application.

The amount of polar solvents, in particular water, may exist in a stoichiometric or unstoichiometric ratio.

As used herein, the term "isomers" refers to chemical compounds with the same number and types of atoms as another chemical species. There are two main classes of isomers, constitutional isomers and stereoisomers.

As used herein, the term "constitutional isomers" refers to chemical compounds with the same number and types of atoms, but they are connected in differing sequences. There are functional isomers, structural isomers, tautomers or valence isomers.

In stereoisomers, the atoms are connected sequentially in the same way, such that condensed formulae for two isomeric molecules are identical. The isomers differ, however, in the way the atoms are arranged in space. There are two major sub-classes of stereoisomers; conformational isomers, which interconvert through rotations around single bonds, and configurational isomers, which are not readily interconvertable.

Configurational isomers are, in turn, comprised of enantiomers and diastereomers. Enantiomers are stereoisomers which are related to each other as mirror images. Enantiomers can contain any number of stereogenic centers, as long as each center is the exact mirror image of the corresponding center in the other molecule. If one or more of these centers differs in configuration, the two molecules are no longer mirror images. Stereoisomers which are not enantiomers are called diastereomers. Diastereomers which still have a different constitution, are another sub-class of diastereomers, the best known of which are simple cis - trans isomers.

In order to limit different types of isomers from each other reference is made to IUPAC Rules Section E {Pure Appl Chem 45, 11 -30, 1976).

The compounds of the present invention can be used in treating diseases of dysregulated vascular growth or diseases which are accompanied by dysregulated vascular growth. Especially, the compounds effectively interfere with angiopoietin and therefore influence Tie2 signalling. Surprisingly, the compounds block Tie2 signalling, wherein Tie2 kinase activity is blocked with showing no or very low cell toxicity for cells other than endothelial cells at low concentrations, which is an important advantage over prior art substances. This effect can therefore allow prolonged treatment of patients with the compounds offering good tolerability and high anti-angiogenic efficacy, where persistent angiogenesis plays a pathologic role.

Therefore the compounds of the present invention can be applied for the treatment of diseases accompanied by neoangiogenesis. This holds principally for all solid tumours, e.g. breast, colon, renal, lung and/or brain tumours and can be extended to a broad range of diseases, where pathologic angiogenesis is persistent. This applies for diseases with inflammatory association, diseases associated with oedema of various forms and diseases associated with stromal proliferation and pathologic stromal reactions broadly. Particularly suited is the treatment for gynaecological diseases where inhibition of angiogenic, inflammatory and stromal processes with pathologic character can be inhibited. At the same time the toxic side effects on normal proliferating tissue are low. The treatment is therefore an addition to the existing armament to treat diseases associated with neoangiogenesis.

The compounds of the present invention can be used in particular in therapy and prevention of tumour growth and metastases especially in solid tumours of all indications and stages with or without pre-treatment if the tumour growth is accompanied with persistent angiogenesis. However it is not restricted to tumour therapy but is also of great value for the treatment of other diseases with dysregulated vascular growth. This includes retinopathy and other angiogenesis dependent diseases of the eye (e.g. cornea transplant rejection, age-related macular degeneration), rheumatoid arthritis, and other inflammatory diseases associated with angiogenesis such as psoriasis, delayed type hypersensitivity, contact dermatitis, asthma, multiple sclerosis, restenosis, pulmonary hypertension, stroke and inflammatory diseases of the bowel, such as Crohn's disease. It includes coronary and peripheral artery disease. It can be applied for disease states such as ascites, oedema, such as brain tumour associated oedema, high altitude trauma, hypoxia induced cerebral oedema, pulmonary oedema and macular oedema or oedema following burns and trauma. Furthermore, it is useful for chronic lung disease, adult respiratory distress syndrome. Also for bone resorption and for benign proliferating diseases such as myoma, benign prostate hyperplasia and wound healing for the reduction of scar formation. It is therapeutically valuable for the treatment of diseases, where deposition of fibrin or extracellular matrix is an issue and stroma proliferation is accelerated (e.g. fibrosis, cirrhosis, carpal tunnel syndrome etc). In addition, it can be used for the reduction of scar formation during regeneration of damaged nerves, permitting the reconnection of axons. Further uses are endometriosis, pre-eclampsia, postmenopausal bleeding and ovarian hyperstimulation.

A second aspect of the invention is a pharmaceutical composition which contains a compound of Formula I or pharmaceutically acceptable salts thereof, isomers or mixtures of isomers thereof, in admixture with one or more suitable excipients. This composition is particularly suited for the treatment of diseases of dysregulated vascular growth or of diseases which are accompanied with dysregulated vascular growth as explained above.

The dosage will necessarily be varied depending upon the route of administration, age, weight of the patient, the kind and severity of the illness being treated and similar factors. The daily dose is in the range of 0.5 - 1 ,500 mg. A dose can be administered as unit dose or in part thereof and distributed over the day. Accordingly the optimum dosage may be determined by the practitioner who is treating any particular patient.

Tie-2 phosphorylates tyrosine residues of the artificial substrate polyGAT (biotinylated polyGluAlaTyr). Detection of phosphorylated product is achieved specifically by a trimeric detection complex consisting of the phosphorylated substrate, streptavidin-XLent (SA-XLent) which binds to biotin, and Europium Cryptate-labeled anti-phosphotyrosine antibody PT66 which binds to phosphorylated tyrosine. Excitation of Europium fluorescence with 337 nm light results in emission of long-lived light with 620 nm. In case a trimeric detection complex has formed, part of the energy will be transferred to the SA-XLent fluorophore that itself then emits long-lived light of 665 nm (FRET: fluorescence resonance energy transfer). Unphosphorylated substrate does not give rise to light emission at 665nm, because no FRET-competent trimeric detection complex can be formed. Measurement is performed in a Packard Discovery or BMG Rubystar instrument. A-counts (emission at 665 nm) will be divided by B-counts (emission at 620 nm) and multiplicated with a factor of 10000. The resulting numbers are called the "well ratio" of the sample.

Biological experiment 3: Proliferation test

To examine cell toxicity a cell proliferation test were established.

With the cell proliferation test different tumour cell lines (e.g. Du 145) can be examined. The cells were dispensed in RPMI 1640 culture medium, supplied with 10 % (v/v) fetal calf serum plus 1 % (v/v) Penicillin /Streptomycin solution at a cell density of 2.000 cell/100μl_ medium/per well (96well plate). After three hours the cells were washed with PBS (containing calcium and magnesium). 100 μl of culture medium above with 0.1 % (v/v) fetal calf serum was added and cultured at 37° C and 5% CO₂-atmosphere. Next day compounds of the present invention diluted in DMSO for appropriate concentrations were added and further 100 μl_ culture medium 0.5 % (v/v) fetal calf serum. After 5 days cell culturing at 37°C and 5% CO₂-atmosphere cells were washed with PBS. 20 μL of glutaraldehyde solution (11 % (v/v)) is added and the cells were slightly shaken at room temperature for 15 min. After that the cell were washed 3 times and dried in the air. 100 μL of crystal violet solution (0.1 % at pH 3.5) were added and the cells were shaken for 30 min. The cells were washed with tap water and air-dried. The colour is dissolved with 100 μL of acetic acid (10 % (v/v)) under strong shaking for 5 min. The absorption was measured at 595 nm wavelength.

The biological experiments show that the compounds presented in this application have high potency activity as inhibitors of Tie2 kinase and Tie2 autophosphorylation as measured with the ELISA-method. The IC50 values are below 1 μM. At the same time the toxicity of the compounds is well above 1 μM which is different to other compounds in this structure class, where the toxicity to tumour cell lines is such, that the IC50 values below 1 μM are observed.

Certain compounds of the invention have been found as potent inhibitors of Tie2. For example the synthesized example compounds 6, 7, 8, 9, 10, 11 , 51 and 52 inhibit Tie2 with an IC50 of about 2 μM or less either in the Tie2 kinase assay or in the Tie2 autophosphorylation ELISA test. While featuring high inhibitory potency against Tie2 kinase activity, certain compounds of the invention have been found to be particularly weakly cytotoxic or non- cytotoxic. More specifically, selected example compounds 6, 7, 8 and 10 showed IC50> 1 μM in the cytotoxicity assay using the cell line DU 145.

Biological experiment 4 : Tie- 2 kinase assay without preactivation of kinase

A recombinant fusion protein of GST and the intracellular domains of Tie-2, expressed in insect cells (Hi-5) and purified by Glutathion-Sepharose affinity chromatography was used as kinase. Alternatively, commercially available GST-Tie2-fusion protein (Upstate Biotechnology, Dundee, Scotland) can be used. As substrate for the kinase reaction the biotinylated peptide biotin-Ahx- EPKDDAYPLYSDFG (C-terminus in amid form) was used which can be purchased e.g. from the company Biosynthan GmbH (Berlin-Buch, Germany). Tie-2 (3.5 ng/measurement point) was incubated for 60 min at 22°C in the presence of 10 μM adenosine-tri-phosphate (ATP) and 1 μM substrate peptide (biotin-Ahx-EPKDDAYPLYSDFG-NH₂) with different concentrations of test compounds (0 μM and concentrations in the range 0.001 - 20 μM) in 5 μl assay buffer [50 mM Hepes/NaOH pH 7, 1O mM MgCl₂, 0.5 mM MnCl₂, 1.0 mM dithiothreitol, 0.01% NP40, protease inhibitor mixture ("Complete w/o EDTA" from Roche, 1 tablet per 2.5 ml), 1 % (v/v) dimethylsulfoxide]. The reaction was stopped by the addition of 5 μl of an aqueous buffer ( 25 mM Hepes/NaOH pH 7.5, 0.28 % (w/v) bovine serum albumin) containing EDTA (90 mM) and the HTRF (Homogeneous Time Resolved Fluorescence) detection reagents streptavidine-XLent (0.2 μM, from Cis Biointernational, Marcoule, France) and PT66-Eu-Chelate (0.3 ng/μl; a europium-chelate labelled anti-phospho- tyrosine antibody from Perkin Elmer). The resulting mixture was incubated 1 h at 22⁰C to allow the binding of the biotinylated phosphorylated peptide to the streptavidine-XLent and the PT66- Eu-Chelate. Subsequently the amount of phosphorylated substrate peptide was evaluated by measurement of the resonance energy transfer from the PT66-Eu-Chelate to the streptavidine-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm was measured in a HTRF reader, e.g. a Rubystar (BMG Labtechnologies, Offenburg, Germany) or a Viewlux (Perkin-Elmer). The ratio of the emissions at 665 nm and at 622 nm was taken as the measure for the amount of phosphorylated substrate peptide. The data were normalised (enzyme reaction without inhibitor = 0 % inhibition, all other assay components but no enzyme = 100 % inhibition) and IC₅₀ values were calculated by a 4 parameter fit using an inhouse software.

Biological experiment 5 : Tie- 2 kinase assay with preactivation of kinase

A recombinant fusion protein of GST and the intracellular domains of Tie-2, expressed in insect cells (Hi-5) and purified by Glutathion-Sepharose affinity chromatography was used as kinase. As substrate for the kinase reaction the biotinylated peptide biotin-Ahx-EPKDDAYPLYSDFG (C-terminus in amid form) was used which can be purchased e.g. from the company Biosynthan GmbH (Berlin-Buch, Germany).

For activation, Tie-2 was incubated at a cone. 12.5 ng/μl of for 20 min at 22⁰C in the presence of 250 μM adenosine-tri-phosphate (ATP) in assay buffer [50 mM Hepes/NaOH pH 7, 10 mM MgCl₂, 0.5 mM MnCl₂, 1.0 mM dithiothreitol, 0.01% NP40, protease inhibitor mixture ("Complete w/o EDTA" from Roche, 1 tablet per 2.5 ml)].

For the subsequent kinase reaction, the preactivated Tie-2 (0.5 ng/ measurement point) was incubated for 20 min at 22⁰C in the presence of 10 μM adenosine-tri-phosphate (ATP) and 1 μM substrate peptide (biotin-Ahx- EPKDDAYPLYSDFG-NH₂) with different concentrations of test compounds (0 μM and concentrations in the range 0.001 - 20 μM) in 5 μl assay buffer [50 mM Hepes/NaOH pH 7, 1O mM MgCl₂, 0.5 mM MnCl₂, 0.1 mM sodium ortho- vanadate, 1.0 mM dithiothreitol, 0.01% NP40, protease inhibitor mixture ("Complete w/o EDTA" from Roche, 1 tablet per 2.5 ml), 1 % (v/v) dimethylsulfoxide]. The reaction was stopped by the addition of 5 μl of an aqueous buffer ( 25 mM Hepes/NaOH pH 7.5, 0.28% (w/v) bovine serum albumin) containing EDTA (90 mM) and the HTRF (Homogeneous Time Resolved Fluorescence) detection reagents streptavidine-XLent (0.2 μM, from Cis Biointemational, Marcoule, France) and PT66-Eu-Chelate (0.3 ng/μl; a europium-chelate labelled anti-phospho-tyrosine antibody from Perkin Elmer). The resulting mixture was incubated 1 h at 22⁰C to allow the binding of the biotinylated phosphorylated peptide to the streptavidine-XLent and the PT66- Eu-Chelate. Subsequently the amount of phosphorylated substrate peptide was evaluated by measurement of the resonance energy transfer from the PT66-Eu-Chelate to the streptavidine-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm was measured in a HTRF reader, e.g. a Rubystar (BMG Labtechnologies, Offenburg, Germany) or a Viewlux (Perkin-Elmer). The ratio of the emissions at 665 nm and at 622 nm was taken as the measure for the amount of phosphorylated substrate peptide. The data were normalised (enzyme reaction without inhibitor = 0 % inhibition, all other assay components but no enzyme = 100 % inhibition) and IC₅₀ values were calculated by a 4 parameter fit using an inhouse software.

The compounds of the present invention are therefore preferentially active as antiangiogenesis inhibitors and not as cytostatic or cytotoxic agents that affect tumour cells and other proliferating tissue cells directly.
