Examples of acids include hydrochloric acid, hydrobromic acid, sulphuric acid, methanesulphonic acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid.
The compounds of general formulae (II) to (VII) used as starting materials are known from the literature in some cases (e.g. from WO 03/82290 or WO 03/082831) or may be obtained using methods known from the literature (cf. Examples I to X), optionally with the additional inclusion of protective groups.
The compounds of general formula I according to the invention and the physiologically acceptable salts thereof have valuable pharmacological properties, in particular an inhibitory action on the signal transduction mediated by the epidermal growth factor receptor (EGF-R), and this can be caused, for example, by an inhibition of ligand binding, receptor dimerisation or tyrosine kinase itself. Moreover, it is possible that the signal transmission to components lying further downstream is blocked.
The biological properties of the novel compounds were tested as follows:
The inhibition of human EGF receptor kinase was determined with the aid of the cyto-plasmic tyrosine kinase domain (methionine 664 to alanine 1186 based on the sequence published in Nature 309 (1984), 418). For this, the protein was expressed in Sf9 insect cells as a GST fusion protein using the Baculovirus expression system.
The measurement of the enzyme activity was carried out in serial dilutions in the presence or absence of the test compounds. The polymer pEY (4:1) from SIGMA was used as a substrate. Biotinylated pEY (bio-pEY) was added as a tracer/substrate. Each 100 μl of reaction solution contained 10 μl of the inhibitor in 50% DMSO, 20 μl of the substrate solution (200 mM HEPES pH 7.4, 50 mM magnesium acetate, 2.5 mg/ml poly(EY), 5 μg/ml bio-pEY) and 20 μl of enzyme preparation. The enzyme reaction was started by addition of 50 μl of a 100 μM ATP solution in 10 mM magnesium chloride. The dilution of the enzyme preparation was adjusted such that the phosphate incorporation into the bio-pEY was linear with respect to time and amount of enzyme. The enzyme preparation was diluted in 20 mM HEPES pH 7.4, 1 mM EDTA, 130 mM sodium chloride, 0.05% Triton X-100, 1 mM DTT and 10% glycerol.
The enzyme assays were carried out at room temperature over a period of 30 minutes and ended by addition of 50 μl of a stop solution (250 mM EDTA in 20 mM HEPES pH 7.4). 100 μl were transferred to a streptavidin-coated microtitre plate and incubated at room temperature for 60 minutes. The plate was then washed with 200 μl of a wash solution (50 mM tris, 0.05% Tween 20). After addition of 100 μl of an HRPO-labelled anti-PY antibody (PY20H Anti-PTyr:HRP from Transduction Laboratories, 250 ng/ml) the mixture was incubated for 60 minutes. The microtitre plate was then washed three times with 200 μl each of wash solution. The samples were then treated with 100 μl of a TMB-peroxidase solution (A:B=1:1, Kirkegaard Perry Laboratories). The reaction was stopped after 10 minutes. The extinction was measured at OD450nm using an ELISA reader. All data points were determined as triplicates.
The data were fitted by means of an iterative calculation using an analysis program for sigmoidal curves (Graph Pad Prism Version 3.0) with a variable Hill pitch. All the iteration data released had a correlation coefficient of over 0.9 and the upper and lower values of the curves showed a spread of at least a factor of 5. From the curves, the active compound concentration was derived which inhibits the activity of the EGF receptor kinase to 50% (IC50). The compounds according to the invention have IC50 values of less than 100 μm. Preferably, the compounds according to the invention have IC50 values of less than 1 μm.
The compounds of the general formula I according to the invention thus inhibit the signal transduction by tyrosine kinases, as demonstrated using the example of the human EGF receptor, and are therefore useful for the treatment of pathophysiological processes which are caused by hyperfunction of tyrosine kinases. These are, for example, benign or malignant tumours, in particular tumours of epithelial and neuroepithelial origin, formation of metastases and the abnormal proliferation of vascular endothelial cells (neoangiogenesis).
The compounds according to the invention are also useful for the prevention and treatment of diseases of the airways and of the lung which are accompanied by increased or altered mucus production, which is caused by stimulation of tyrosine kinases, such as, for example, in inflammatory diseases of the airways such as acute bronchitis, chronic bronchitis, chronic obstructive bronchitis (COPD), asthma, bronchiectases, allergic or non-allergic rhinitis or sinusitis, cystic fibrosis, α1-antitrypsin deficiency, or coughs, pulmonary emphysema, pulmonary fibrosis and hyperreactive airways, as well as acute and chronic diseases of the nasal mucosa and nasal sinuses, such as acute and chronic rhinitis, sinusitis and nasal polyps.
The compounds are also suitable for treating inflammatory diseases of the gastrointestinal tract and bile duct and gall bladder which are associated with disrupted activity of the tyrosine kinases, such as may be found e.g. In acute or chronic inflammatory changes such as cholecystitis, Crohn's disease, ulcerative colitis, and ulcers or polyposis in the gastrointestinal tract or such as may occur in diseases of the gastrointestinal tract which are associated with increased secretions, such as Ménétrier's disease, secreting adenomas or protein loss syndromes, and also for treating inflammatory diseases of the joints, such as rheumatoid arthritis, inflammatory diseases of the skin, the eyes, in inflammatory pseudopolyps, in colitis cystica profunda or pneumatosis cystoides intestinalis. The compounds may also be used for treating CNS and spinal cord injuries.
Preferred fields of application are inflammatory diseases of the respiratory organs or of the intestine, such as chronic bronchitis (COPD), chronic sinusitis, asthma, Crohn's disease, ulcerative colitis or polyposis of the intestines.
Particularly preferred fields of application are inflammatory diseases of the airways or lungs such as chronic bronchitis (COPD) or asthma or diseases of the nasal mucosa and sinus mucosa as well as nasal polyps.
Moreover, the compounds of general formula (I) and the physiologically acceptable salts thereof can be used for the treatment of other diseases caused by aberrant function of tyrosine kinases, such as, for example epidermal hyperproliferation (psoriasis), benign prostatic hyperplasia (BPH), inflammatory processes, diseases of the immune system, hyperproliferation in haematopoietic cells, the treatment of nasal polyps, etc.
On account of their biological properties, the compounds according to the invention can be used alone or in combination with other pharmacologically active compounds, for example in tumour therapy in monotherapy or in combination with other antitumour therapeutics, for example in combination with topoisomerase inhibitors (e.g. etoposide), mitosis inhibitors (e.g. vinblastine), compounds interacting with nucleic acids (e.g. cis-platin, cyclophosphamide, adriamycin), hormone antagonists (e.g. tamoxifen), inhibitors of metabolic processes (e.g. 5-FU etc.), cytokines (e.g. Interferons), antibodies etc. For the treatment of diseases in the region of the gastrointestinal tract, these compounds can likewise be given alone or in combination with motility- or secretion-influencing substances. These combinations can be administered either simultaneously or sequentially.
For the treatment of airway diseases, these compounds can be used alone or in combination with other airway therapeutics, such as, for example, compounds having secretolytic activity (e.g. ambroxol, N-acetylcysteine), broncholytic activity (e.g. tiotropium or ipratropium or fenoterol, salmeterol, salbutamol) and/or anti-inflammatory activity (e.g. theophylline or glucocorticoids).
