## Background
RELATED APPLICATION

No. 11/244,299 filed Oct. 5, 2005, which claims priority benefits of German Application No. 10 2004 048 877 filed Oct. 7, 2004 and German Application No. 10 2005 005 813 filed Feb. 9, 2005, respectively, all of which are incorporated by reference herein.


TECHNICAL FIELD
Phosphatidylinositol-3-kinases (PI3-kinases) are a subfamily of the lipid kinases which catalyse the transfer of a phosphate group to the 3′-position of the inositol ring of phosphoinositides (Vanhaesebroeck and Waterfield, Exp Cell Res. 1999 Nov. 25; 253(1):239-54).
They have an important role in numerous cell processes such as e.g. cell growth and differentiation processes, the control of cytoskeletal changes and the regulation of intracellular transport processes (Vanhaesebroeck et al., Annu Rev Biochem. 2001; 70:535-602). In view of their in vitro specificity for particular phosphoinositide substrates the PI3-kinases may be divided into various classes. The members of the receptor-regulated class I are heterodimeric enzymes which are made up of a catalytic subunit (p110) weighing 110-120 kDa and a non-catalytic subunit (p50, p55, p85, p101) weighing 50-101 kDa. The most highly conserved region in all the PI3-kinases is the C-terminally situated kinase domain. It has structural features which can also be found in the majority of known protein kinases. These also include e.g. highly conserved amino acids which are responsible for the coordination of the ATP molecule (Walker et al., Nature. 1999 Nov. 18; 402(6759):313-20).
Three of the four members of the class I PI3-kinases associate constitutively with an adaptor subunit weighing 50-85 kDa, of which p85 is the prototype. The interaction takes place via the so-called p85 binding domain which can be found on the catalytic subunits of the PI3-kinase α, β and δ. The three forms are grouped in class IA on account of this structural feature. The catalytic subunit γ of the PI3-kinase, p110γ, associates instead with a regulatory protein weighing 101 kDa, which is known as p101. It constitutes Class IB of the PI3-kinases—of which it is currently the sole member. This structural division into class IA and IB also shows parallels in the functional properties of the corresponding PI3-kinase isoforms (Vanhaesebroeck and Waterfield, Exp Cell Res. 1999 Nov. 25; 253(1):239-54)
Thus, the PI3-kinase α, β and δ are activated predominantly by receptor-tyrosine-kinases (RTKs) or soluble tyrosine kinases. The p85-subunit serves as an adaptor, as it is able to recognise and bind the phosphorylated tyrosine groups of specific amino acid sequences (YxxM) with its SH2 domains. The PI3Kγ on the other hand is activated mainly by Gβγ-subunits which are released from heterotrimeric G-proteins after activation of heptahelical receptors. This differing coupling to cell surface receptors combined with a more or less restrictive expression necessarily results in very different tasks and functions for the 4 class I PI3-kinases in the intact organism (Wymann et al., Trends Pharmacol Sci. 2003 July; 24(7):366-76).
A number of independent findings would appear to indicate that class IA PI3-kinases are involved in uncontrolled cell growth and differentiation processes. Thus, the first detected PI3-kinase activity was associated with the transforming activity of viral oncogenes, such as e.g. the middle T antigen of polyomaviruses, Src tyrosine kinases or activated growth factors (Workman, Biochem Soc Trans. April; 32(Pt 2):393-6). In many tumours, such as e.g. breast cancer, ovarian or pancreatic carcinoma, there is found to be an overactivity of Akt/PKB, which is activated directly by the lipid products of class I PI3-kinases and thus transmits the signals on into the cell. Moreover, it was found just recently that the PIK3CA-gene which codes for p110α has a high mutation frequency in various types of tumour, such as colon, breast or lung carcinomas, some examples of which were able to be characterised as activating mutations (Samuels et al., Science. 2004 Apr. 23; 304(5670):554).
The most recent member of the class IA PI3-kinases, PI3Kδ, is expressed more restrictively than PI3Kα and β. In so-called “knock-in” mice in which the catalytic subunit of PI3Kδ, p110δ, had been replaced by an inactive mutant, it was demonstrated that this PI3K-isoenzyme plays a specific part in the signal transmission of B- and T-lymphocytes after antigen receptor stimulation (Okkenhaug et al., Science. 2002 August; 297(5583):1031-4). These are mechanisms which play a part especially in autoimmune diseases such as e.g. Crohn's disease or rheumatoid arthritis.
The PI3Kγ is activated almost exclusively by Gi-coupling heptahelical receptors. Thus, in neutrophils in mice which express no PI3Kγ, no PI3,4,5-P3 formation was observed if they were stimulated with IL-8, fMLP, LTB4 or C5a (Hirsch et al., Science. 2000 Feb. 11; 287(5455):1049-53). This shows that at least in this type of cell PI3Kγ is the only PI3-kinase isoform which binds to these heptahelical receptors. Moreover, isolated neutrophils and macrophages from the PI3Kγ-deficient mice exhibited a sharply reduced chemotactic activity or production of oxygen radicals compared with a whole series of chemokines and chemoattractors. Also reduced was the IgE-mediated activation of mast cells which had been isolated from p110γ-deficient mice. There has been some discussion that the mechanism responsible might be a positive feedback mechanism in which the PI3Kγ is activated by Gi-coupling adenosine A3 receptors (Laffargue et al., Immunity. 2002 March; 16(3):441-51).
In spite of this decreased ability to react to inflammation mediators, the p110γ-deficient mice have normal viability and reproductive powers and have the same life expectancy as wild-type comparison animals reared identically. From this it can be concluded that the class IB PI3Kγ plays a central role in the activation of various inflammatory cells, and therefore isoform-specific inhibitors represent an attractive possibility for anti-inflammatory therapy with comparatively minor side effects (Ward and Finan, Curr Opin Pharmacol. 2003 August; 3(4):426-34). Apart from its function in leukocytes PI3Kγ also appears to be involved in the cardiovascular system, despite its low expression in cardiomyocytes. Thus, p110γ-deficient mice exhibited an increase in cardiac muscle contractility which may presumably be explained by an overproduction of cAMP (Crackower et al., Cell. 2002 Sep. 20; 110(6):737-49). It has only recently been possible to demonstrate that PI3Kγ is also involved in the development of cardiac hypertrophy. Thus, p110γ-deficient mice exhibited significantly reduced hypertrophy and fibrosis compared with wild-type animals in an isoproterenol-induced cardiac insufficiency model (Oudit et al., Circulation. 2003 Oct. 28; 108(17):2147-52).
The problem of the present invention was to provide new compounds which by virtue of their pharmaceutical efficacy as PI3-kinase modulators may be used in the therapeutic field for the treatment of inflammatory or allergic diseases. Examples which may be mentioned here include inflammatory and allergic respiratory complaints, inflammatory diseases of the gastrointestinal tract, rheumatoid arthritis, inflammatory and allergic skin diseases, inflammatory eye diseases, diseases of the nasal mucosa, inflammatory or allergic conditions involving autoimmune reactions, or inflammation of the kidneys.

Some compounds which may be prepared by one of the methods of synthesis described above are hereinafter listed by way of example. All the melting points (mp) are given in ° C. In order to determine the inhibitory activity of the compounds on PI3Kγ, an in-vitro kinase assay is set up which is based on the transfer of the terminal γ-phosphate of ATP to phosphatidylinositol-4,5-bisphosphate (PIP2). The enzyme activity used is the Gβ1γ2-His stimulated PI3Kγ. The expression and purification of Gβ1γ2-His and p101-GST/p110γ from Sf9-cells (Spodoptera frugiperda 9) has already been described (Maier et al., J. Biol. Chem. 1999 (274) 29311-29317).
The kinase assay is carried out in white 384-well flat-bottomed dishes. Each well contained 5 μl of the compound to be tested which had been dissolved in assay buffer (40 mM Hepes, pH 7.5, 100 mM NaCl, 1 mM EGTA, 1 mM β-glycerophosphate, 1 mM DTT, 7 mM MgCl2 and 0.1% BSA; 6% DMSO). 15 μl of lipid vesicles containing 10 ng of PI3Kγ and 31.5 ng of Gβ1γ2-His were added in each case. The lipid vesicles in turn were generated by suspending PIP2 (0.35 μg/well), phosphatidyl ethanolamine (3.75 μg/well), phosphatidyl serine (3.5 μg/well), sphingomyelin (0.35 μg/well) and phosphatidyl choline (1.6 μg/well) in lipid buffer (assay buffer without DMSO) by ultrasound treatment. After the addition of the lipid vesicles the reaction is started by the addition of 10 μl reaction buffer (40 mM Hepes, pH 7.5, 100 mM NaCl, 1 mM EGTA, 1 mM β-glycerophosphate, 1 mM DTT, 7 mM MgCl2 and 0.1% BSA; 1 μM ATP and 0.2 μCi [γ-33P]-ATP). The reaction mixture is incubated in this way for 1 h and then stopped by the addition of a suspension of 0.12 mg LEADseeker beads (Amersham Biosciences) in stop buffer (40 mM Hepes, pH 7.5, 100 mM NaCl, 1 mM EGTA, 12 mM EDTA, 1 mM β-glycerophosphate, 1 mM DTT). After 1 minute's centrifugation at 500×g the plates were read and analysed using a LEADseeker apparatus. All the compounds shown have an IC50 value of less than 800 nM in the test.

Moreover, the compounds of formula 1 are suitable for therapeutic use in cases of inflammatory or allergic complaints which involve autoimmune reactions, such as e.g. inflammatory bowel diseases, e.g. Crohn's disease or ulcerative colitis; diseases of the arthritis type, such as e.g. rheumatoid or psoriatic arthritis, osteoarthritis, rheumatoid spondylitis and other arthritic conditions or multiple sclerosis.
The following general inflammatory or allergic diseases may also be mentioned, which can be treated with medicaments containing compounds of formula 1:

    
    
        inflammation of the eye, such as e.g. conjunctivitis of various kinds, e.g. caused by infections with fungi or bacteria, allergic conjunctivitis, irritable conjunctivitis, drug-induced conjunctivitis, keratitis, uveitis
        diseases of the nasal mucosa, such as e.g. allergic rhinitis/sinusitis or nasal polyps
        inflammatory or allergic conditions, such as e.g. systemic lupus erythematodes, chronic hepatitis, kidney inflammations such as glomerulonephritis, interstitial nephritis or idiopathic nephrotic syndrome.
    
    


Other diseases which may be treated with a drug containing compounds of formula 1 on the basis of their pharmacological activity include toxic or septic shock syndrome, atherosclerosis, middle ear infections (otitis media), hypertrophy of the heart, cardiac insufficiency, stroke, ischaemic reperfusion injury or neurodegenerative diseases such as Parkinson's disease or Alzheimer's.
Combinations
The compounds of formula 1 may be used on their own or in conjunction with other active substances of formula 1 according to the invention. If desired the compounds of general formula 1 may also be used in conjunction with other pharmacologically active substances.
Preferably active substances are used which are selected, for example, from among the betamimetics, anticholinergics, corticosteroids, PDE4-inhibitors, LTD4-antagonists, EGFR-inhibitors, dopamine-agonists, H1-antihistamines, PAF-antagonists and PI3-kinase inhibitors or double or triple combinations thereof, such as for example combinations of

    
    
        Betamimetics with corticosteroids, PDE4-inhibitors, EGFR-inhibitors or LTD4-antagonists,
        Anticholinergics with betamimetics, corticosteroids, PDE4-inhibitors, EGFR-inhibitors or LTD4-antagonists,

For inhalation, according to the invention, solutions containing 0.01 to 1.0, preferably 0.1 to 0.5% active substance are suitable. For administration by inhalation the use of powders, ethanolic or aqueous solutions is preferred. It is also possible to use the compounds according to the invention as a solution for infusion, preferably in a physiological saline or nutrient saline solution.
The compounds according to the invention may be used on their own or in conjunction with other active substances according to the invention, optionally also in conjunction with other pharmacologically active substances. Suitable formulations include, for example, tablets, capsules, suppositories, solutions, syrups, emulsions or dispersible powders. Corresponding tablets may be obtained for example by mixing the active substance(s) with known excipients, for example inert diluents, such as calcium carbonate, calcium phosphate or lactose, disintegrants such as maize starch or alginic acid, binders such as starch or gelatine, lubricants such as magnesium stearate or talc and/or agents for delaying release, such as carboxymethyl cellulose, cellulose acetate phthalate, or polyvinyl acetate. The tablets may also comprise several layers.
Coated tablets may be prepared accordingly by coating cores produced analogously to the tablets with substances normally used for tablet coatings, for example collidone or shellac, gum arabic, talc, titanium dioxide or sugar. To achieve delayed release or prevent incompatibilities the core may also consist of a number of layers. Similarly the tablet coating may consist of a number of layers to achieve delayed release, possibly using the excipients mentioned above for the tablets.
Syrups containing the active substances or combinations thereof according to the invention may additionally contain a sweetener such as saccharine, cyclamate, glycerol or sugar and a flavour enhancer, e.g. a flavouring such as vanillin or orange extract. They may also contain suspension adjuvants or thickeners such as sodium carboxymethyl cellulose, wetting agents such as, for example, condensation products of fatty alcohols with ethylene oxide, or preservatives such as p-hydroxybenzoates.
Solutions for injection are prepared in the usual way, e.g. with the addition of preservatives such as p-hydroxybenzoates, or stabilisers such as alkali metal salts of ethylenediamine tetraacetic acid, and transferred into injection vials or ampoules.
Capsules containing one or more active substances or combinations of active substances may for example be prepared by mixing the active substances with inert carriers such as lactose or sorbitol and packing them into gelatine capsules. Suitable suppositories may be made for example by mixing with carriers provided for this purpose, such as neutral fats or polyethyleneglycol or the derivatives thereof.
