Definitions

  • PTKs Protein tyrosine kinases
  • PTKs can be of the receptor-type (having extracellular, transmembrane and intracellular domains) or the non-receptor type (being wholly intracellular).
  • signal transduction mediated by receptor tyrosine kinases (“RTKs”) is initiated by extracellular interaction with a specific growth factor (i.e., a ligand), followed by receptor dimerization, transient stimulation of the intrinsic protein tyrosine kinase activity and phosphorylation. Binding sites are thereby created for intracellular signal transduction molecules and lead to the formation of complexes with a spectrum of cytoplasmic signaling molecules that facilitate the appropriate cellular response (e.g., cell division, metabolic homeostasis, and responses to the extracellular microenvironment).
  • RTKs receptor tyrosine kinases
  • tyrosine phosphorylation sites function as high-affinity binding sites for SH2 (src homology) domains of signaling molecules.
  • SH2 serosine phosphorylation sites
  • Several intracellular substrate proteins that associate with RTKs have been identified and are divided into two principal groups: (1) substrates which have a catalytic domain; and (2) substrates which lack a catalytic domain but serve as adapters and associate with catalytically active molecules.
  • the specificity of the interactions between receptors or proteins and SH2 domains of their substrates is determined by the amino acid residues immediately surrounding the phosphorylated tyrosine residue.
  • RTKs The intrinsic function of RTKs is activated upon ligand binding, which results in phophorylation of the receptor and multiple cellular substrates, and subsequently in a variety of cellular responses. At present, at least nineteen distinct RTK subfamilies have been identified.
  • One RTK subfamily designated the HER subfamily, is believed to be comprised of EGFR, HER2, HER3 and HER4.
  • Ligands to the HER subfamily of receptors include epithelial growth factor (EGF), TGF- , amphiregulin, HB-EGF, betacellulin and heregulin.
  • the second subfamily of RTKs, designated the insulin subfamily is comprised of the INS-R, the IGF-1R and the IR-R.
  • the third RTK subfamily includes the PDGF ⁇ and receptors, CSFIR, c- kit and FLK-II.
  • Another subfamily of RTKs, identified as the FLK family is believed to be comprised of the kinase insert domain-receptor fetal liver kinase-1 (KDR/FLK-1), the fetal liver kinase 4 (FLK-4) and the fms-like tyrosine kinase 1 (flt-1). Each of these receptors was initially believed to be a receptor for hematopoietic growth factors.
  • RTKs Two other subfamilies of RTKs have been designated as the FGF receptor family (FGFR1, FGFR2, FGFR3 and FGFR4) and the Met subfamily (c-met and Ron). Because of the similarities between the PDGF and FLK subfamilies, the two subfamilies are often considered together.
  • the known RTK subfamilies are identified in Plowman et al, 1994, DN&P 7(6): 334-339, which is incorporated herein by reference.
  • the non-receptor tyrosine kinases represent a collection of cellular enzymes which lack extracellular and transmembrane sequences.
  • non- receptor tyrosine kinases comprising eleven subfamilies (Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack and LIMK) have been identified.
  • the Src subfamily of non- receptor tyrosine kinases is comprised of the largest number of PTKs, and include Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr and Yrk.
  • the Src subfamily of enzymes has been linked to oncogenesis.
  • non-receptor tyrosine kinases A more detailed discussion of non-receptor tyrosine kinases is provided in Bolen, 1993, Oncogen 8: 2025-2031, which is incorporated herein by reference. Many of the protein tyrosine kinases (PTKs), whether an RTK or non-receptor tyrosine kinase, have been found to be involved in cellular signaling pathways leading to cellular signal cascades and pathogenic conditions such as cancer, psoriasis and hyper immune responses.

FIELD OF THE INVENTION The present invention is directed to novel compounds with multiple aromatic
components capable of modulating, regulating and/or inhibiting tyrosine kinase signal transduction. The present invention is also directed to methods of prevention and/or treatment of disorders related to unregulated tyrosine kinase signal transduction, including but not limited to, cell growth disorders, metabolic disorders, blood vessel proliferative disorders, inflammatory disorders, neurodegenerative diseases and immune disorders. BACKGROUND OF THE INVENTION Protein tyrosine kinases (“PTKs”) play an important role in the control of cell growth and differentiation. PTKs comprise a large and diverse class of proteins having enzymatic activity. PTKs can be of the receptor-type (having extracellular, transmembrane and intracellular domains) or the non-receptor type (being wholly intracellular). For example, signal transduction mediated by receptor tyrosine kinases (“RTKs”) is initiated by extracellular interaction with a specific growth factor (i.e., a ligand), followed by receptor dimerization, transient stimulation of the intrinsic protein tyrosine kinase activity and phosphorylation. Binding sites are thereby created for intracellular signal transduction molecules and lead to the formation of complexes with a spectrum of cytoplasmic signaling molecules that facilitate the appropriate cellular response (e.g., cell division, metabolic homeostasis, and responses to the extracellular microenvironment). With respect to RTKs, it has been shown also that tyrosine phosphorylation sites function as high-affinity binding sites for SH2 (src homology) domains of signaling molecules. Several intracellular substrate proteins that associate with RTKs have been identified and are divided into two principal groups: (1) substrates which have a catalytic domain; and (2) substrates which lack a catalytic domain but serve as adapters and associate with catalytically active molecules. The specificity of the interactions between receptors or proteins and SH2 domains of their substrates is determined by the amino acid residues immediately surrounding the phosphorylated tyrosine residue. Differences in binding affinities between SH2 domains and the amino acid sequences surrounding the phosphotyrosine residues on particular receptors are consistent with the observed differences in their substrate phosphorylation profiles. These observations suggest that the function of each RTK is determined not only by its pattern of expression and ligand availability, but also by the array of downstream signal transduction pathways that are activated by a particular receptor. Thus, phosphorylation provides an important regulatory step which determines the selectivity of signaling pathways recruited by specific growth factor receptors, as well as differentiation factor receptors. The RTKs comprise a large family of transmembrane receptors with diverse biological activities. The intrinsic function of RTKs is activated upon ligand binding, which results in phophorylation of the receptor and multiple cellular substrates, and subsequently in a variety of cellular responses. At present, at least nineteen distinct RTK subfamilies have been identified. One RTK subfamily, designated the HER subfamily, is believed to be comprised of EGFR, HER2, HER3 and HER4. Ligands to the HER subfamily of receptors include epithelial growth factor (EGF), TGF- , amphiregulin, HB-EGF, betacellulin and heregulin. The second subfamily of RTKs, designated the insulin subfamily, is comprised of the INS-R, the IGF-1R and the IR-R. The third RTK subfamily, the“PDGF” family, includes the PDGF α and receptors, CSFIR, c- kit and FLK-II. Another subfamily of RTKs, identified as the FLK family, is believed to be comprised of the kinase insert domain-receptor fetal liver kinase-1 (KDR/FLK-1), the fetal liver kinase 4 (FLK-4) and the fms-like tyrosine kinase 1 (flt-1). Each of these receptors was initially believed to be a receptor for hematopoietic growth factors. Two other subfamilies of RTKs have been designated as the FGF receptor family (FGFR1, FGFR2, FGFR3 and FGFR4) and the Met subfamily (c-met and Ron). Because of the similarities between the PDGF and FLK subfamilies, the two subfamilies are often considered together. The known RTK subfamilies are identified in Plowman et al, 1994, DN&P 7(6): 334-339, which is incorporated herein by reference. The non-receptor tyrosine kinases represent a collection of cellular enzymes which lack extracellular and transmembrane sequences. At present, over twenty-four individual non- receptor tyrosine kinases, comprising eleven subfamilies (Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack and LIMK) have been identified. At present, the Src subfamily of non- receptor tyrosine kinases is comprised of the largest number of PTKs, and include Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr and Yrk. The Src subfamily of enzymes has been linked to oncogenesis. A more detailed discussion of non-receptor tyrosine kinases is provided in Bolen, 1993, Oncogen 8: 2025-2031, which is incorporated herein by reference. Many of the protein tyrosine kinases (PTKs), whether an RTK or non-receptor tyrosine kinase, have been found to be involved in cellular signaling pathways leading to cellular signal cascades and pathogenic conditions such as cancer, psoriasis and hyper immune responses. In view of the importance of PTKs to the control, regulation and modulation of cell proliferation and the diseases and disorders associated with abnormal cell proliferation, many attempts have been made to identify receptor and non-receptor tyrosine kinase“inhibitors” using a variety of approaches, including the use of mutant ligands (U.S. Patent No. 4,966,849), soluble receptors and antibodies (Kendall & Thomas, 1994, Proc. Nat’l Acad. Sci 90: 10705-09; Kim, et al, 1993, Nature 362: 841-844), RNA ligands (Jellinek, et al, Biochemistry 33: 10450-56); Takano, et al, 1993, Mol. Bio. Cell 4:358A; Kinsella, et al, 1992, Exp. Cell Res. 199: 56-62; Wright, et al, 1992, J. Cellular Phys. 152: 448-57) and tyrosine kinase inhibitors (U.S. Patent No. 5,330,992; Mariani, et al, 1994, Proc. Am. Assoc. Cancer Res. 35: 2268). More recently, attempts have been made to identify small molecules which act as tyrosine kinase inhibitors. For example, bis monocyclic, bicyclic or heterocyclic aryl compounds (PCT Application No. WO 92/20642), vinylene-azaindole derivatives (PCT Application No. WO 94/14808) and 1-cyclopropyl-4-pyridyl-quinolones (U.S. Patent No. 5,330,992) have been described generally as tyrosine kinase inhibitors. Styryl compounds (U.S. Patent No. 5,217,999), styryl-substituted pyridyl compounds (U.S. Patent No. 5,302,606), certain quinazoline derivatives (EP Application No. 0566 266 A1), seleoindoles and selenides (PCT Application No. WO 94/03427), tricyclic polyhydroxylic compounds (PCT Application No. WO 92/21660) and benzylphosphonic acid compounds (PCT Application No. WO 91/15495) have been described as compounds for use as tyrosine kinase inhibitors for use in the treatment of cancer. In addition, other small molecules were studied as tyrosine kinase inhibitors, such as the compounds disclosed in U.S. Pat. Nos. 6,765,012; 6,541,504; 6,747,025; 5,792,783; 5,834,504; 5,883,113; 5,883,116 and 5,886,020, all of which are incorporated by reference in their entireties. The identification and use of compounds which specifically inhibit signal transduction by modulating the activity of receptor and non-receptor tyrosine is one aspect of the present invention. SUMMARY OF THE INVENTION The present invention is directed to compounds represented by Formula I capable of modulating, regulating and/or inhibiting tyrosine kinase signal transduction, and uses of the compounds and compositions incorporating the compounds for disease treatment and prevention. The compounds of the present invention can be found in general Formula I:

and including any pharmaceutically acceptable salt or prodrug. Unless otherwise indicated, reference to a compound should be construed broadly to include compounds, pharmaceutically acceptable salts, prodrugs, tautomers, stereoisomers, diastereoisomers, alternate solid forms, crystal forms, polymorphic forms, hydrates, solvates, metabolites, mixtures of stereoisomers, mixtures of crystal forms, non-covalent complexes, and combinations thereof, of a chemical entity of a depicted structure or a chemical name. Whenever there is a conflict between chemical name and its structure drawing, the structure drawing should be used to interpret the compound of the present invention. A pharmaceutically acceptable salt is any salt of the parent compound that is suitable for administration to an animal or human. A pharmaceutically acceptable salt also refers to any salt which may form in vivo as a result of administration of an acid, another salt, or a prodrug which is converted into an acid or salt. A salt comprises one or more ionic forms of the compound, such as a conjugate acid or base, associated with one or more corresponding counter-ions. Salts can form from or incorporate one or more deprotonated acidic groups (e.g. carboxylic acids), one or more protonated basic groups (e.g. amines), or both (e.g. zwitterions). A "prodrug" is a compound, which when administered to the body of a subject (such as a mammal), breaks down in the subject's metabolic pathway to provide an active compound of Formula I. More specifically, a prodrug is an active or inactive "masked" compound that is modified chemically through in vivo physiological action, such as hydrolysis, metabolism and the like, into a compound of this invention following administration of the prodrug to a subject or patient. One common form of a prodrug is a masked carboxylic acid group. Examples of a masked carboxylate anion include a variety of esters, such as alkyl (for example, methyl, ethyl), cycloalkyl (for example, cyclohexyl), aralkyl (for example, benzyl, p-methoxybenzyl), and alkylcarbonyloxyalkyl (for example, pivaloyloxymethyl). Amines have been masked as arylcarbonyloxymethyl substituted derivatives which are cleaved by esterases in vivo releasing the free drug and formaldehyde (Bundgaard J. Med. Chem. 2503 (1989)). Also, drugs containing an acidic NH group, such as imidazole, imide, indole and the like, have been masked with N- acyloxymethyl groups (Bundgaard Design of Prodrugs, Elsevier (1985)). Hydroxy groups have been masked as esters and ethers. EP 039,051 (Sloan and Little, Apr. 11, 1981) discloses Mannich-base hydroxamic acid prodrugs, their preparation and use.For example, conversion may occur by hydrolysis of an ester group or some other biologically labile group. Prodrug preparation is well known in the art. For example,“Prodrugs and Drug Delivery Systems,” which is a chapter in Richard B. Silverman, Organic Chemistry of Drug Design and Drug Action, 2d Ed., Elsevier Academic Press: Amsterdam, 2004, pp. 496-557, provides further detail on the subject.

3.2 Biological Testing Biological data for the compounds of the present invention was generated by the use of one or more of the following assays. VEGF Stimulated Ca.sup.++ Signal in Vitro Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of VEGF induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. HUVEC (human umbilical vein endothelial cells) (Clonetics) were seeded in 96-well fibronectin coated black-walled plates overnight at 37.degree. C./5%
CO.sub.2. Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37.degree. C. Cells were washed 4 times (Original Cell Wash, Labsystems) to remove extracellular dye. Test compounds were reconstituted in 100% DMSO and added to the cells to give a final DMSO concentration of 0.1%. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10.mu.M) or at concentrations ranging from 0.01 to 10.0.mu.M followed by VEGF stimulation (5 ng/mL). Changes in fluorescence at 516 nm were measured simultaneously in all 96 wells using a cooled CCD camera. Data were generated by determining max-min fluorescence levels for unstimulated, stimulated, and drug treated samples. IC.sub.50 values for test compounds were calculated from % inhibition of VEGF stimulated responses in the absence of inhibitor. VEGFR2 Kinase Assay The cytoplasmic domain of the human VEGF receptor (VEGFR-2) was expressed as a Histidine-tagged fusion protein following infection of insect cells using an His engineered baculovirus. His-VEGFR-2 was purified to homogeneity, as determined by SDS-PAGE, using nickel resin chromatography. Kinase assays were performed in 96 well microtiter plates that were coated overnight with 30.mu.g of poly-Glu-Tyr (4:1) in 10 mM Phosphate Buffered Saline (PBS), pH 7.2-7.4. The plates were incubated with 1% BSA and then washed four times with PBS prior to starting the reaction. Reactions were carried out in 120.mu.L reaction volumes containing 3.6 .mu.M ATP in kinase buffer (50 mM Hepes buffer pH 7.4, 20 mM MgCl.sub.2, 0.1 mM MnCl.sub.2 and 0.2 mM Na.sub.3 VO.sub.4). Test compounds were reconstituted in 100% DMSO and added to the reaction to give a final DMSO concentration of 5%. Reactions were initiated by the addition 0.5 ng of purified protein. Following a ten minute incubation at 25.degree. C., the reactions were washed four times with PBS containing 0.05% Tween-20. 100 .mu.l of a monoclonal anti-phosphotyrosine antibody-peroxidase conjugate was diluted 1:10000 in PBS-Tween-20 and added to the wells for 30 minutes. Following four washes with PBS- Tween-20, 100.mu.l of O-phenylenediamine Dihydrochloride in Phosphate-citrate buffer, containing urea hydrogen peroxide, was added to the wells for 7 minutes as a colorimetric substrate for the peroxidase. The reaction was terminated by the addition of 100.mu.l of 2.5N H.sub.2 SO.sub.4 to each well and read using a microplate ELISA reader set at 492 nm.
IC.sub.50 values for compound inhibition were calculated directly from graphs of optical density (arbitrary units) versus compound concentration following subtraction of blank values.
Compounds of the current invention have the IC50 value in the range of 0.01 to 500 nM. VEGF-induced Dermal Extravasation in Guinea Pig (Miles Assay) Male Hartley guinea pigs (300-600 g) were anesthetized with isofluorane, sheared, and given a single dose of drug or the respective vehicle. The guinea pigs were dosed orally unless indicated otherwise in Table 3. Ten minutes prior to the end of drug treatment, guinea pigs were anesthetized with isofluorane, and 0.5% Evans blue dye (EBD) in PBS (13-15 mg/kg dose of EBD) was injected intravenously. After 5 minutes, triplicate intradermal injections of 100 ng rhVEGF.sub.165 in 100.mu.l PBS and of 100.mu.l PBS alone were administered on the flank. After 20 minutes, each animal was cuthanized with Pentosol, and the skin containing the intradermal injection sites was removed for image analysis. Using an analog video camera coupled to a PC, an image of each trans-illuminated skin sample was captured, and the integrated optical density of each injection site was measured using ImagePro 4. For each skin sample, the difference between the mean optical density of the VEGF sites and mean optical density of the PBS sites is the measure of VEGF-induced EBD extravasation in that animal. These measured values were averaged per study group to determine the mean VEGF-induced EBD extravasation for each experimental condition, and the group means were then compared to assess inhibition of VEGF-induced EBD extravasation in the drug-treated groups relative to the vehicle-treated controls. To determine the dose required for 50% inhibition (ID.sub.50), the percent inhibition data was plotted as a function of oral dose, using the `best-fit` analysis within MicroSoft Excel software. The ID.sub.50 value was verified visually by using the plotted data (horizontal line from 50% y value, at intersection with best-fit line drop vertical line to x axis (dose). Laser-induced Choroidal Neovascularization (CNV) in Rat (CNV Assay). CNV was induced and quantified in this model as previously described (Edelman and Castro. Exp. Eye Res. 2000; 71:523-533). On day 0, male Brown Norway rats (200-300 g) were anesthetized with 100 mg/kg Ketamine and 10 mg/kg Xylazine, and pupils were dilated with 1% Tropicamide. Using the blue-green setting of a Coherent Novus Argon Laser, 3 laser bums (90 mW for 0.1 s; 100 .mu.m diameter) were given to each eye between the retinal vessels around the optic nerve head. Rats were dosed with test compounds in their indicated vehicles orally once daily. On day 10, rats were sacrificed with 100% CO.sub.2, and blood vessels were labeled by vascular perfusion with 10 mg/ml FITC-dextran (MW 2.times.10.sup.6). Using an
epifluorescence microscope (20.times.) coupled to a spot digital camera and a PC, images were obtained from the flat mounts of the RPE-choroid-sclera from each eye, and the area occupied by hyperfluorescent neovessels within each laser lesion was measured using ImagePro 4 software. To determine the dose required for 50% inhibition (ID.sub.50), the percent inhibition data was plotted as a function of oral dose, using the `best-fit` analysis within MicroSoft Excel software. The ID.sub.50 value was verified visually by using the plotted data (horizontal line from 50% y value, at intersection with best-fit line drop vertical line to x axis (dose). The foregoing description can be employed to practice the present invention, and represents the best mode contemplated. It should not be construed as limiting the overall scope hereof.

Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of PDGF induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. NHDF-Ad (Normal human dermal fibroblasts) (Lonza) were seeded in 384-well fibronectin coated black-walled plates overnight at 37° C/5% CO2 . Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37° C. Cells were washed 4 times (ELx405- CW, Bio-Tek) to remove extracellular dye. Test compounds were reconstituted in 100% DMSO and added to the cells to give a final DMSO concentration of 0.1%. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10 µM) or at concentrations ranging from 0.001nM to 10 µM followed by PDGF stimulation (10 ng/mL). Changes in fluorescence at 515nm were measured simultaneously in all 384 wells using a cooled CCD camera. Data were generated by determining max-min fluorescence levels for
unstimulated, stimulated, and drug treated samples. IC50 values for test compounds were calculated from % inhibition of PDGF stimulated responses in the absence of inhibitor. Table II and III present the biodata of some of the compounds of the present invention.
