Technical Field
The present invention relates to novel bipyridine derivatives, to the use of said compounds in the inhibition, regulation and/or modulation of signal transduction by ATP consuming proteins, such as kinases, in particular to inhibitors of TGF-beta receptor kinases, and to the use of said compounds for the treatment of kinase induced diseases.
Prior Art
Many kinds of proteins that bind to ATP and use its energy to change conformation, phosphorylate substrates, and initiate signaling cascades are known, such as kinases, phosphatases, chaperones, or isomerases. ATP-binding proteins can be enriched using specific tools and techniques.
Tyrosine kinase and serine threonine kinase subfamilies have been identified from the large family of protein kinases, a partial list including cAbl, Akt, ALK1 and family members thereof such as ALK1 and ALK5, Axl, Aurora a and B, Btk, Dyrk2, EGFR, Erk, Ephrin (Ephrin) receptors such as EphA2, FAK, FGF receptors such as FGFR3, insulin receptor IR and insulin-like growth factor receptor IGF1R, IKK2, Jak2, JNK3, cKit, LimK, VEGF receptors 1,2 and 3, Mek1, Met, P70s6K, PDGFR, PDK1, PI3K, Plk1, PKD1, bRaf, RSK1, Src and family members thereof, TAK1, TrkA, B, C, Zap 70. The different kinases can be described by multiple synonyms, well known to those skilled in the art, reports of genes and proteins and links to alternative names, classes, gene annotations, sequences and gene structures, and pdb3D structural information can be found in databases such as Kinweb. Similarly, proteomics servers allow access to information for many genes and proteins (including kinases) as well as analytical and predictive tools.
As part of the mechanism of cancer markers, Ser/Thr kinases and Receptor Tyrosine Kinases (RTKs) are required phosphorylases in cell signaling. Cell cycle, survival, proliferation and cell death are all cellular processes that are regulated by cellular signaling, allowing tissue growth, regeneration and maintenance of homeostasis or regression. Thus, some kinases are keen targets for mammalian therapy.
Among the different families of kinases that are part of the human kinase group (kineme), the receptor tyrosine kinase KDR (also known as VEGF receptor 2) can stimulate the survival and proliferation of endothelial cells if it is extracellularly linked by VEGF. Ligand binding then leads to intracellular phosphorylation events, signaling cascades, and ultimately to proliferation. Various treatments attempt to inhibit the delivery of the KDR signal.
Other kinases and ligands important to the function of endothelial cells are TIE2 kinase and angiogenin, PDGF receptors and PDGF and PIGF, ephrin receptor kinase and ephrin, especially EphB4 and ephrin-B2. In addition, the ligand TGF β and its receptor TGF β R (i.e., Alk1/Alk5) play an important role in maintaining vascular integrity. By binding to the TGF β II receptor, TGF β can activate 2 different type I receptors in endothelial cells, namely EC-localized ALK1 and widely expressed ALK5, which have opposite effects on the behavior of EC. ALK1 stimulates EC proliferation and migration via Smad1/5 transcription factors, and ALK5 inhibits these functions via Smad2/3 transcription factors. An example of an Alk5 kinase inhibitor that contributes to EC proliferation and layer formation is SB-431542. Inhibition of ligand binding may be another method of modulating TGF receptor signaling also present in angiogenesis. This has been demonstrated with 2 peptides and also discussed in terms of soluble TGF receptor T β R-Fc. The use of anti-TGF β antibodies, and even TGF β capture agents, would be another strategy to inhibit TGF β signaling.
TGF-beta proteins include a family of conserved dimeric proteins with molecular weights of 25kDa, which are ubiquitously expressed and secreted in an inactive form. Local proteolysis in response to appropriate stimuli results in active TGF ligand. TGF β signaling is involved in a number of conditions and diseases, including cancer, cardiovascular disease, bone disease, CNS disease, PNS disease, inflammatory disease, and neurodegenerative disease.
In epithelial cells, TGF β inhibits cell proliferation. The transition from normal epithelial cells to cancer cells is accompanied by a down-regulation in response to growth inhibition by TGF β, thereby allowing the cells to evade autocrine tumor suppressor activity of TGF β signaling. The increase in TGF β production by cancer cells promotes cancer cell invasion and metastatic behavior. TGF β can induce epithelial to mesenchymal transition (EMT), which makes cells invasive and migratory. Furthermore, the increase in TGF β production exerts an effect on stromal cells and immune cells, providing a favorable microenvironment for cancer progression. TGF-beta proteins signal through T-beta R-I/II receptor kinases and their Smad substrates, but may also be Smad independent signaling, such as ERK MAP kinase, PI3 kinase, Rho-like GTPase, protein phosphatase 2A and Par 6. Activated type I T β R kinases enhance cell survival and can accelerate pathological cell progression.
Type I and type II TGF β receptors (T β R I, T β R II) are single channel transmembrane intracellular serine/threonine kinases that provide binding receptors for extracellular ligands (TGF β). Intracellular signaling occurs through autophosphorylation, transphosphorylation and substrate phosphorylation, resulting in modulation of target gene expression. The cloning and genomic organization of the T β R protein is well known. The T β R sequence is deposited at www.uniprot.org under accession number P36897 as TGFR1_ human and under accession number P37173 as TGF β R2_ human. At the protein level, type I tsr is described as containing a Gly and Ser rich region (GS domain) followed by a receptor kinase domain. T β R II is a constitutively active kinase in its autophosphorylation/phosphorylation state, which binds to type I receptors and phosphorylates them in the GS domain.
The tsr receptor is a tetrameric complex of 2 tss R I and 2 tss R II units, to which the ligand TGF β binds (activated), phosphorylates smads (Smad2 and Smad3) as substrates at their C-terminal SSXS motifs, which in turn bind to Smad 4/are bound by Smad4 to be translocated to the nucleus where they regulate TGF β responsive genes. Different domains that regulate the formation of homomeric and heteromeric complexes in type I and type II T β rs are known. Mutations in the GS domain of T β R I may be constitutively active. The kinase inactivating mutation of type I T β R was found to be K232R and the kinase inactivating mutation of type II T β R was found to be K277R. Inactivating or attenuating mutations of type I and type II T β R genes are found in a variety of cancers. In addition, signaling of tsr is regulated by phosphorylation and dephosphorylation mechanisms, ubiquitination (ubiquitination) and sumoylation (sumoylation), and by endocytosis and TACE-mediated shedding of the extracellular domain of type I, but not type II receptor TACE (akaADAM-17), which mediates shedding of cytokines, GF receptors and adhesion proteins and is highly expressed in cancer.
The X-ray co-crystal (co-crystal) structures of T β R I and FKBP12 have been described, and the kinase activation process has also been discussed. Meanwhile, a variety of crystal structures can be found in the PDB database: 1B6C, 1IAS, 1PY5, 1RW8, 1VJY, 2PJY and model 1 TBI. For T β R II, only X-ray studies of extracellular ligand binding domains are known: 1KTZ, 1M9Z and 1plo (nmr), but no kinase domain.
TGF β signalling involves the sole substrate for Smad-type I T β R receptor kinase. The human genome encodes eight Smads from 3 subfamilies (R-, Co-, I-Smad), which are ubiquitously expressed throughout developmental processes and adult tissues. Smads are not only phosphorylated by TGF β type I receptor kinases, but they are also regulated by oligomerization, ubiquitination and degradation, and nuclear shuttling.
VEGF release has been shown to be regulated by ALK1 and ALK5, whereas TGF β enhances VEGF expression and BMP-9 inhibits VEGF expression.
Studies with the truncated isoform of ALK4 show that this type I kinase is involved in the growth and development of pituitary tumors through dominant negative inhibition of activin signaling. Spatiotemporal window studies of the role of ALK4 in embryonic development, regulation of mesoderm induction, primitive streak formation, gastrulation, major axis formation, and left-right axis determination have not yet elucidated the role of ALK4 in adults.
In a large-scale human candidate screen, the dominant negative ALK2 allele was found to be associated with congenital heart disease such as inappropriate atrioventricular compartment development.
ALK1 binds to T β R-II and endoglin/CD 105/T β R-III and phosphorylates SMAD-1 and SMAD-5. The role of endoglin, particularly the differential regulation of TGF signaling by the two variants (L-and S-endoglin), has been demonstrated. ALK1 functions in vascular remodeling and is found to balance the activation state of the endothelium in inflamed tissues, wounds, and tumors, along with ALK 5. ALK1 is expressed in the lungs, placenta, and other highly vascularized tissues and is selectively found in ECs. ALK1 was also detected on neurons.
Loss of type II T β R expression is associated with high tumor levels of human breast cancer, suggesting that it promotes breast cancer progression. Tumor growth may be characterized by unregulated, i.e., autonomous, cell growth due to disruption of RTK signaling by mutations or other genetic changes. Of the 32000 human coding genes involved in signal transduction, more than 520 protein kinases and 130 protein phosphatases exert tight, reversible control over protein phosphorylation. Selectivity was found for tyrosine and serine/threonine phosphorylation. There are more than 90 known PTK genes in the human genome, more than 50 encoding transmembrane RPTK distributed in 20 subfamilies, and 32 non-receptor PTKs encoding cytoplasm in 10 subfamilies. For example, Trk a plays an important role in thyroid cancer and neuroblastoma, EphB2 and B4 are overexpressed in cancer, Axl and Lck are overexpressed in leukemia.
TGF β inhibitors have been reviewed for use in the treatment of cancer. There are additional indications and pathologies that are indirectly targeted to cancer, wound healing and inflammation through anti-angiogenesis, vascular formation, stabilization, maintenance and degeneration.
Angiogenesis (the development of new blood vessels from pre-existing vessels) is critical in vascular development in embryogenesis, organogenesis and wound healing. In addition to these physiological processes, angiogenesis is important for tumor growth, metastasis and inflammation, leading to diseases such as tumors of the breast, cervix, uterus (endometrium), ovary, lung, bronchi, liver, kidney, skin, oral cavity and pharynx, prostate, pancreas, bladder, blood cells, colon, rectum, bone, brain, central and peripheral nervous system, e.g., breast cancer, colorectal cancer, glioma, lymphoma, etc., as well as inflammatory diseases such as rheumatoid arthritis and psoriasis, or ocular diseases such as macular degeneration and diabetic retinopathy. The molecular mechanisms of the angiogenic switch in angiogenesis and tumorigenesis have been recently discussed. Angiogenesis is regulated by Eph receptor tyrosine kinases and ephrin ligands (e.g., ephrin-B2 signaling by Eph B4 and Eph B1). EphB4 controls vascular morphogenesis during postnatal angiogenesis. Maturation of neovasculature formed by angiogenesis or vasculogenesis requires the production of mural cells (pericytes, smooth muscle cells), extracellular matrix and specialization of the vessel wall for structural support and regulation of vessel function. The regulation of these processes and the interaction between endothelial cells and their parietal cells involve a variety of ligand kinase pairs, such as VEGF/VEGFR1, VEGFR2, ephrin B2/EphB4, PDGFR/PDGFR β, angiopoietin/TIE 2, TGF β/TGF β R-ALK1/ALK 5. Vascular assembly, capillary formation, sprouting, stabilization and destabilization, and even regression, are regulated by the functional balance of these kinases and ligands. Lymphangiogenesis (lymphangiogenesis) is regulated by VEGF receptor 3 and its ligands VEGF C and D and TIE2 and its ligand angiopoietins 1, 2. Inhibition of VEGFR3 and/or TIE2 signaling, and thus inhibition of lymphatic vessel formation, may be one means of stopping tumor cell metastasis. The overall information on pathological angiogenesis led to the hypothesis that: inhibition of angiogenesis is a promising strategy for the treatment of cancer and other disorders.
The importance of TGF β receptors for the angiogenic process was shown by Alk1, endoglin, Alk5, and T β RII KO mice, which exhibit an embryonic lethal phenotype due to vascular defects. Furthermore, in EC, TGF β ligands can stimulate two pathways, namely Smad1/5/8 phosphorylation downstream of Alk1 and Smad2/3 phosphorylation downstream of Alk 5. The two paths interfere with each other. Alk5 knock-in mice with the L45 loop mutation showed defective Smad activation. In EC, TGF β/Alk5 signaling is antagonized by ALK 1.
TGF β exists in at least five isoforms (TGF β 1-5), all of which are unrelated to TGF α, TGF β 1 being a prevalent form. TGF β is a ubiquitous, essential regulator of cellular and physiological processes including proliferation, differentiation, migration, cell survival, angiogenesis and immune surveillance.
Since cancer cells express tumor-specific antigens, they are generally recognized by the immune system and destroyed. During tumorigenesis, cancer cells acquire the ability to evade this immune surveillance through a variety of mechanisms. One major mechanism is cancer cell-mediated immunosuppression by secretion of TGF β, a potent immunosuppressive cytokine. TGF β has the potential to convert from tumor suppressors to tumor promoters and prometastatic factors. The function of TGF β is transmitted by a tetrameric receptor complex consisting of two sets of transmembrane serine-threonine kinase receptors, termed type I and type II receptors, which are activated upon engagement of members of the TGF β superfamily of ligands (which are divided into 2 groups, TGF β/activin and BMP/GDF branches). TGF-beta 1,2, and 3 belong to the TGF-beta/activin ligand branch. These binding events detail downstream responses that are differentially regulated in different cell types.
The importance of fibroblasts in the mesenchymal-epithelial cell interaction of the skin during wound repair is described in the postnatal TGF β RII deletion inducible in skin fibroblasts. During wound repair, the expression of the ligand TGF β and its receptors type RI and RII is regulated both temporally and spatially. CD109 (a GPI-linked cell surface antigen expressed by CD34+ acute myeloid leukemia cell line, EC, activated platelets and T cells) is part of the T β R system in human keratinocytes. Hair Follicle Stem Cells (FSCs) in the hair follicle bulge region can give rise to multiple lineages during the hair cycle and during wound healing. Smad4 (a common mediator of TGF β signaling) is part of FSC maintenance. Smad4KO studies in mouse skin showed the formation of hair follicle defects and squamous cell carcinoma. Potential TGF β inhibition delays the hair growth metaphase process in the hair follicle. The role of TGF β in keratinocyte apoptosis during catagen, which has been well described, may involve specific follicular components of anagen, which are also involved in co-localized T β R and T β RII.
Abnormal activity of TGF β in fibrosis of various organs such as skin, kidney, heart and liver is known, which is the rationale for the use of T β R inhibitors in fibrotic diseases. Systemic sclerosis (scleroderma), a complex disorder of connective tissue leading to fibrosis of the skin and internal organs, has been shown to be TGF β/receptor RI dependent. Pulmonary Arterial Hypertension (PAH) is a potential treatment disorder with ALK5 inhibitors, as abnormal proliferation of peripheral arterial smooth muscle cells is driven by activated TGF β receptors. Treatment with SB525334 was successful in rats. Benefits were also shown with IN-1233 IN rats. Renal fibrosis can lead to diabetes.
The beneficial side effects of TbetaR kinase inhibitor derivatives and the link between TGF signaling and Hepatitis C Virus (HCV) replication are known. TGF signaling is discussed as an emerging stem cell target in metastatic breast cancer. TGF β 1,2,3 and their receptors are expressed in neurons, astrocytes and microglia. TGF signaling modulators can be expected to improve pathological outcomes. The TGF β superfamily in cardiovascular diseases such as atherosclerosis, myocardial ischemia and cardiac remodeling is the focus of cardiovascular research issues.
Further details regarding the biological activity of TGF β are disclosed in WO2009/004753, which is incorporated by reference in its entirety into the present invention.
Furthermore, RON kinase is a valuable target in tumor biology (Wagh et al (2008) Adv Cancer Res.100: 1-33). The Met-related receptor tyrosine kinase RON is involved in tumor growth and metastasis. RON receptors are members of the Met family of cell surface receptor tyrosine kinases and are expressed primarily on epithelial cells and macrophages. The biological response of RON is mediated by the binding of its ligand, hepatocyte growth factor-like protein/macrophage stimulating protein (HGFL). HGFL is synthesized and secreted from hepatocytes, mainly in the form of an inactive precursor, and is activated on the cell surface. Binding of HGFL to RON activates RON and leads to the induction of various intracellular signaling cascades leading to cell growth, motility and invasion. Recent studies have demonstrated the overexpression of RON in a variety of human cancers including breast, colon, liver, pancreas and bladder cancers. In addition, clinical studies have shown that RON overexpression is associated with poor prognosis and metastasis in patients. Forced overexpression of RON in transgenic mice leads to tumorigenesis in the lungs and mammary glands and is associated with metastatic spread. Although overexpression of RON appears to be a hallmark of many human cancers, the mechanism by which RON induces tumorigenesis and metastasis remains unclear. Several strategies are currently being undertaken to inhibit RON as a potential therapeutic target; current strategies include the use of RON blocking proteins, small interfering rnas (sirnas), monoclonal antibodies, and small inhibitors. Overall, these data suggest that RON is a key factor in tumorigenesis and that inhibition of this protein alone or in combination with other current therapies may prove beneficial in the treatment of cancer patients.
Furthermore, TAK1 or CHK2 are valuable targets in the immune and Cell damage response pathways (Delaney & Mlodzik (2006) Cell Cycle5(24):2852-5, a new insight describing the various roles of TGF- β activated kinase-1 and TAK1 in development and immunity. many recent publications have examined the role of TAK1 in model systems from flies to mice. TAK1 appears to play a role in signaling nodes responding to various upstream signals (including inflammatory molecules and developmental cues) rather than following a well-defined linear molecular pathway. then TAK1 affects many downstream processes from innate immune response to patterning and differentiation through JNK, NF κ B and TCF β -catenin signaling. these functional differences are not simply a matter of Cell type. Depending on the nature of the activation signal. Interestingly, the multitasking function of TAK1 is conserved among vertebrates and invertebrates. The study of TAK1 in various experimental systems has the potential to reveal more roles of this kinase, and to elucidate the mechanism by which other signaling molecules fulfill different signaling roles.
Furthermore, checkpoint kinases Chk1 and Chk2 are Ser/Thr protein kinases that function as key regulatory kinases in cellular DNA damage response pathways, limiting cell cycle progression in the presence of DNA damage. The development of checkpoint kinase inhibitors for the treatment of cancer is a major goal of drug development in the past decade, as demonstrated by three checkpoint kinase inhibitors that have entered clinical trials since the last 2005. A number of chemically diverse inhibitors of Chk1 and Chk2 kinase have been described in recent patent literature. Common structural motifs for checkpoint kinase inhibitors have been identified. Currently there are three checkpoint kinase inhibitors in clinical development, which is a continuing effort by the pharmaceutical industry to identify new structural scaffolds for checkpoint kinase inhibition (Janetka & Ashwell (2009) expertOpin Ther paper.200919 (2): 165-97).

The pharmaceutical preparations can be used as medicaments in human and veterinary medicine. The term "effective amount" as used herein means an amount of a drug or pharmaceutical substance that will elicit the biological or medical response of a tissue, system, animal or human that is being sought, for example, by a researcher or clinician. Furthermore, the term "therapeutically effective amount" means any amount that results in an improved treatment, cure, prevention or amelioration of a disease, disorder or side effect or a reduction in the rate of progression of a disease or disorder as compared to a corresponding individual not receiving that amount. The term also includes within its scope an amount effective to enhance normal physiological function. The therapeutically effective amount of the one or more compounds of the invention is known to those skilled in the art or can be readily determined by standard methods known in the art.
The compounds of the invention and the further active substances are generally applied analogously to the commercial preparations. In general, suitable dosages for therapeutic effectiveness lie in the range from 0.0005mg to 1000mg, preferably from 0.005mg to 500mg, in particular from 0.5mg to 100mg per dosage unit. The daily dosage is preferably between about 0.001mg/kg body weight and 10mg/kg body weight.
One skilled in the art will readily appreciate that dosage levels may vary depending on the particular compound, the severity of the symptoms, and the individual's susceptibility to side effects. Some specific compounds are more effective than others. Preferred dosages for a given compound can be readily determined by one skilled in the art using a variety of methods. One preferred method is to determine the physiological potency of a given compound.
For the purposes of the present invention, all mammalian species are included. In a preferred embodiment, the mammal is selected from the group consisting of "primate, human, rodent, equine, bovine, canine, feline, farm animal, bovine, livestock, pet, cow, sheep, pig, goat, horse, pony (pony), donkey, mule, horse mule, rabbit, cat, dog, guinea pig, hamster, rat, mouse". More preferably, the mammal is a human. Animal models are important for experimental studies, providing a model for the treatment of human disease.
However, the specific dose for each individual patient depends on numerous factors, such as the potency of the specific compound used, the age, body weight, general health, sex, dietary type, time and route of administration, rate of excretion, type and dosage form of administration, drug combination and the severity of the particular disorder involved in the treatment. The specific therapeutically effective amount for each patient can be readily determined by routine experimentation, for example, by the physician or physician providing the advice and charge for treatment.
In the case of many disorders, the susceptibility of a particular cell to treatment with a subject compound may be determined by in vitro assays. Typically, cell cultures are mixed with varying concentrations of the subject compounds for a period of time sufficient for the active agents to exhibit a relevant response, usually about 1 hour to one week. For in vitro assays, cultured cells of a biopsy sample may be used.
Those skilled in the art will be able to utilize the above description to its fullest extent, even if not in any further detail. The preferred embodiments are therefore to be considered in all respects as illustrative and not restrictive.
Above and below, all temperatures are given in ° C. In the following examples, "conventional workup" means removal of the solvent if necessary, addition of water if necessary, adjustment of the pH to a value of between 2 and 10 if necessary, depending on the constitution of the end product, extraction of the mixture with ethyl acetate or dichloromethane, separation of the phases, separation of the organic layer with saturated NaHCO3The solution is washed, if desired with water and saturated NaCl solution, dried over sodium sulfate, filtered and evaporated, and the product is purified by chromatography on silica gel, preparative HPLC and/or crystallization.

Assay method
Example 14: cellular assays for detecting TGF-beta receptor I kinase inhibitors
As an example, the ability of the inhibitor to abrogate TGF- β mediated growth inhibition was tested. The lung epithelial cell line cells Mv1Lu were seeded at a defined cell density in 96-well microtiter plates and cultured overnight under standard conditions. The following day, the medium was replaced with a medium containing 0.5% FCS and 1ng/ml TGF-. beta.and the test substance (typically 5-fold serial dilutions) was added at the determined concentration. The concentration of the solvent DMSO was constant at 0.5%. After a further two days, crystal violet staining of the cells was performed. After extraction of crystal violet from the fixed cells, the absorbance was measured spectrophotometrically at 550 nm. It can be used as a quantitative measure of the presence of adherent cells and thus of the proliferation of cells during the culture.
Example 15: inhibition of Smad2/3 phosphorylation of Mv1Lu cells by TGF-beta receptor I kinase inhibitors
This assay was used to determine the inhibitory potency of compounds on TGF- β mediated phosphorylation of Smad2(Ser465/467) and Smad3(Ser 423/425). Mv1-Lu cells (lung epithelial cell line, from mine Mustella vison; ATCC No. CCL-64) were seeded in 24-well or 96-well plates (24-well plates: 1.5X 10. sup. th. the cell density was determined in DMEM (Invitrogen) supplemented with 10% fetal bovine serum (PanBiotech)5Individual cells/well; 96-well plate: 4X 104Individual cells/well). Cell cultures were grown in DMEM at 37 ℃ and 10% CO2And (4) incubating. The following day, the medium was replaced and the cells were serum starved for 16-20 hours. The following day, serial dilutions of the compound were added to each well, preincubated for 1.5 hours, and recombinant TGF-. beta.1 ligand (final concentration 5ng/ml; R)&Dsystems). After 1 hour of ligand stimulation, lysates were prepared and analyzed using an enzyme-linked immunoassay Kit (PathScan phosphor-Smad 2Kit, Cell Signaling Technologies). ELISA detects phosphorylated Smad2 and phosphorylated Smad3 using phospho-specific antibodies. TGF- β stimulated and unstimulated cells were used as positive and recessive controls (100% and background controls). The concentration of medium DMSO was kept constant at 0.2% (v/v) in all wells. Dose-response relationships were fitted using a curve fitting algorithm of the RS1 Statistical software package (Brooks Automation Inc. RS/1-Statistical Tools handbook. Release6.2) to determine the concentration at which half-maximal inhibition of Smad2/3 phosphorylation was achieved (IC 2/3 phosphorylation)50)。
