Definitions
- This invention relates to compounds that inhibit the binding of proteins containing an SH2 domain to cognate phosphorylated proteins. This invention also relates to pharmaceutical compositions containing the compounds and to therapeutic methods that use the compounds.
- tyrosine kinases Many of the signal transduction pathways that regulate a variety of cellular processes, including the differentiation and proliferation of normal and malignant cells, operate through phosphorylated proteins called tyrosine kinases.
- the two major types of tyrosine kinases are receptor and nonreceptor tyrosine kinases.
- Receptor tyrosine kinases contain binding sites or receptors for growth factors such as epidermal growth factor (EGF) or platelet-derived growth factor (PDGF) .
- EGF epidermal growth factor
- PDGF platelet-derived growth factor
- the tyrosine kinase receptor protein When a growth factor such as EGF or PDGF binds to the receptor, the tyrosine kinase receptor protein is activated; the tyrosine kinase receptor protein is autophosphorylated; and endogenous proteins that participate in the signal transduction pathway are phosphorlyated.
- SH2 domain a specific domain that provides for interaction with an activated tyrosine kinase receptor protein. This interaction is a protein- protein interaction.
- One protein that contains an SH2 domain is pp60c-src kinase, which is also a tyrosine kinase.
- the pp60c-src kinase is a nonreceptor kinase and is related to a number of nonreceptor tyrosine kinases, which include, but are not limited to, Fyn, Lck, Yes, Blk, Lyn, Fgr, Hck, and Yrk.
- the pp60c-src protein is exemplary of the Src family of tyrosine kinases.
- the pp60c-src has three major domains: SHI, SH2, and SH3.
- SHI domain is most commonly called the catalytic domain or tyrosine kinase domain.
- SH3 domain is a binding region for proteins having proline-rich sequences. Both the SH2 and SH3 domains are noncatalytic, but are important in protein-protein recognition.
- the Src family of protein kinases which all contain a SH2 domain, are involved in a number of cellular signalling pathways. For example, Src is involved in growth factor receptor signalling; integrin-mediated signaling; T- and B-cell activation and osteoclast activation. It is known that the Src SH2 domain binds to several key receptor and nonreceptor tyrosine kinases such as tyrosine kinases containing receptors for PDGF, EGF, HER2/Neu (an oncogene form of EGF), Fibroblast growth factor, focal adhesion kinase, pl30 protein, and p68 protein. In addition, pp60c-src has been shown to be involved in the regulation of DNA synthesis, mitosis, and other cellular activities.

Description
COMPOUNDS, COMPOSITIONS AND METHODS FOR INHIBITING THE
BINDING OF PROTEINS CONTAINING AN SH2 DOMAIN
TO COGNATE PHOSPHORYLATED PROTEINS
FIELD OF THE INVENTION
This invention relates to compounds that inhibit the binding of proteins containing an SH2 domain to cognate phosphorylated proteins. This invention also relates to pharmaceutical compositions containing the compounds and to therapeutic methods that use the compounds.
BACKGROUND OF THE INVENTION
Many of the signal transduction pathways that regulate a variety of cellular processes, including the differentiation and proliferation of normal and malignant cells, operate through phosphorylated proteins called tyrosine kinases. The two major types of tyrosine kinases are receptor and nonreceptor tyrosine kinases. Receptor tyrosine kinases contain binding sites or receptors for growth factors such as epidermal growth factor (EGF) or platelet-derived growth factor (PDGF) . When a growth factor such as EGF or PDGF binds to the receptor, the tyrosine kinase receptor protein is activated; the tyrosine kinase receptor protein is autophosphorylated; and endogenous proteins that participate in the signal transduction pathway are phosphorlyated.
Some endogenous proteins that are involved in the cellular signal transduction pathways contain a specific domain called the SH2 domain, which provides
for interaction with an activated tyrosine kinase receptor protein. This interaction is a protein- protein interaction. One protein that contains an SH2 domain is pp60c-src kinase, which is also a tyrosine kinase. The pp60c-src kinase is a nonreceptor kinase and is related to a number of nonreceptor tyrosine kinases, which include, but are not limited to, Fyn, Lck, Yes, Blk, Lyn, Fgr, Hck, and Yrk. Another important protein that contains an SH2 domain is Abl. The pp60c-src protein is exemplary of the Src family of tyrosine kinases. The pp60c-src has three major domains: SHI, SH2, and SH3. The SHI domain is most commonly called the catalytic domain or tyrosine kinase domain. The SH3 domain is a binding region for proteins having proline-rich sequences. Both the SH2 and SH3 domains are noncatalytic, but are important in protein-protein recognition.
The Src family of protein kinases, which all contain a SH2 domain, are involved in a number of cellular signalling pathways. For example, Src is involved in growth factor receptor signalling; integrin-mediated signaling; T- and B-cell activation and osteoclast activation. It is known that the Src SH2 domain binds to several key receptor and nonreceptor tyrosine kinases such as tyrosine kinases containing receptors for PDGF, EGF, HER2/Neu (an oncogene form of EGF), Fibroblast growth factor, focal adhesion kinase, pl30 protein, and p68 protein. In addition, pp60c-src has been shown to be involved in the regulation of DNA synthesis, mitosis, and other cellular activities.
Thus, it would be useful to have compounds that inhibit the binding of proteins containing an SH2 domain to cognate phosphorylated proteins, as the inhibition of binding of proteins containing an SH2 domain to cognate phosphorylated proteins can be used
to treat proliferative diseases such as cancer, osteoporosis, inflammation, allergy, restenosis, and cardiovascular disease, which all rely on signal transduction involving proteins that contain an SH2 domain that binds to phosphorylated proteins during the cellular signalling process.

The compounds and pharmaceutically acceptable compositions that contain the compounds can be administered to humans and animals either orally, rectally, parenterally (intravenous, by intramuscularly or subcutaneously) , intracisternally, intravaginally, intraperitoneally, intravesically, locally (powders, ointments or drops), or as a buccal or nasal spray. Compositions suitable for parenteral injection may comprise physiologically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions, or emulsions and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (propyleneglycol, polyethyleneglycol, glycerol, and the like), suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.
These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispensing agents. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin. Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In
such solid dosage forms, the active compound is admixed with at least one inert customary excipient (or carrier) such as sodium citrate or dicalcium phosphate or (a) fillers or extenders, as for example, starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders, as for example, carboxymethylcellulose, alignates, gelatin, polyvinylpyrrolidone, sucrose and acacia, (c) humectants, as for example, glycerol,
(d) disintegrating agents, as for example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain complex silicates and sodium carbonate,

(f) absorption accelerators, as for example, quaternary ammonium compounds, (g) wetting agents, as for example, cetyl alcohol and glycerol monostearate,
(h) adsorbents, as for example, kaolin and bentonite, and (i) lubricants, as for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in soft- and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethyleneglycols, and the like.
Solid dosage forms such as tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells, such as enteric coatings and others well known in the art. They may contain opacifying agents, and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedding compositions which can be used are polymeric substances and waxes. The active compounds can also be in micro-encapsulated form, if
appropriate, with one or more of the above-mentioned excipients.
Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art, such as water or other solvents, solubilizing agents and emulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propyleneglycol, 1,3-butyleneglycol, dimethylformamide, oils, in particular, cottonseed oil, groundnut oil, corn germ oil, olive oil, castor oil and sesame oil, glycerol, tetrahydrofurfuryl alcohol, polyethyleneglycols, and fatty acid esters of sorbitan or mixtures of these substances, and the like.
Besides such inert diluents, the composition can also include adjuvants, such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
Suspensions, in addition to the active compounds, may contain suspending agents, as for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, or mixtures of these substances, and the like.
Compositions for rectal administrations are preferably suppositories which can be prepared by mixing the compounds of the present invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethyleneglycol or a suppository wax, which are solid at ordinary temperatures but liquid at body temperature and therefore, melt in the rectum or vaginal cavity and release the active component.
Dosage forms for topical administration of a compound of this invention include ointments, powders, sprays and inhalants. The active component is admixed under sterile conditions with a physiologically acceptable carrier and any preservatives, buffers or propellants as may be required. Ophthalmic formulations, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention. The term "pharmaceutically acceptable salts, esters, amides, and prodrugs" as used herein refers to those carboxylate salts, amino acid addition salts, esters, amides and prodrugs of the compounds of the present invention which are, within the scope of sound medical judgement, suitable for use in contact with the tissues of patients without undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit/risk ratio, and effective for their intended use, as well as the zwitterionic forms, where possible, of the compounds of the invention. The term "salts" refers to the relatively non-toxic, inorganic and organic acid addition salts of compounds of the present invention. These salts can be prepared in situ during the final isolation and purification of the compounds or by separately reacting the purified compound in its free base form with a suitable organic or inorganic acid and isolating the salt thus formed. Representative salts include the hydrobro ide, hydrochloride, sulfate, bisulfate, nitrate, acetate, oxalate, valerate, oleate, palmitate, stearate, laurate, borate, benzoate, lactate, phosphate, tosylate, citrate, maleate, fumarate, succinate, tartrate, naphthylate mesylate, glucoheptonate, lactiobionate and laurylsulphonate salts, and the like.

Examples of suitable phosphoesters include, but are not limited to -P03RcRd,
-CF2P03RcRd, and -CH2P03RcRd, where Rc and Rd are as defined above. (See, for example, Jones R.J. and Bischofberger N., "Minireview: nucleotide prodrugs", Antiviral Research, 1995;27:1-17, which is incorporated herein by reference.
Examples of pharmaceutically acceptable, non-toxic amides of the compounds of this invention include amides derived from ammonia, primary C-^-Cg alkyl amines and secondary Cj-C dialkyl amines wherein the alkyl groups are straight or branched chain. In the case of secondary amines, the amine may also be in the form of a 5- or 6-membered heterocycle containing one nitrogen atom. Amides derived from ammonia, C-^- ^ alkyl primary amides and C _C2 dialkyl secondary amides are preferred. Amides of the compounds of the invention may be prepared according to conventional methods.
The term "prodrug" refers to compounds that are rapidly transformed in vivo to yield the parent compound of the above formulas, for example, by hydrolysis in blood. A thorough discussion is provided in T. Higuchi and V. Stella, "Pro-drugs as Novel
Delivery Systems," Vol. 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Druσ Desiσn, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference.
The compounds of the present invention can be administered to a patient at dosage levels in the range of about 1 to about 7,000 mg/day. For a normal human adult having a body weight of about 70 kg, a dosage in the range of about 1 to about 100 mg/kg of body weight per day is sufficient. The specific dosage used, however, can vary. For example, the dosage can depend on a number of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used. The determination of optimum dosages for a particular patient is well known to those skilled in the art.
The compounds of the present invention can exist in different stereoisometric forms by virtue of the presence of asymmetric centers in the compounds. It is contemplated that all stereoisometric forms of the compounds as well as mixture thereof, including racemic mixtures, form part of this invention. In addition, the compounds of the present invention can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the present invention.

Inhibition of 125I-Phosphopeptide Binding to Immobilized Src SH2
The binding affinities of compounds of the present invention to Src SH2 was determined using a competitive radiolabeled phosphopeptide displacement assay.
Specifically, binding of 125I-labeled Glu-Pro-Gln-pTyr- Glu-Glu-Ile-Pro-Ile-Tyr-Leu or 125I-labeled Glu-Pro- Gln- (4-(difluorophosphonomethyl) )-Phe-Glu-Glu-Ile-Pro- Ile-Tyr-Leu to a glutathione-S-transferase(GST) -Src SH2 fusion protein was performed in 20 mM Tris (pH 7.5), 150 mM NaCl, 5 mM EDTA, and 0.1% NP-40. Assay additions to a Millipore filter plate (0.45 mM PVDF) resulted in Src SH2 fusion protein-glutathione sepharose bead complex, 2.8 DH 125I-phosphopeptide and 2% DMSO + test compound at different concentrations. Binding was performed at room temperature for 20 minutes while continuously inverting the plate. Unbound 125I-phosphopeptide was separated from SH2-bound radiolabeled peptide by vacuum filtration and washing two times with 100 μL per well of assay buffer. Results are expressed as IC50 values in Table 1 below. Inhibition of Activated PDGF Receptor Binding to 35S-SH2 Domains
The binding of compounds of the present invention have been determined using 35S-labeled GST SH2 protein constructs and their binding to an immobilized PDGF receptor kinase domain. Binding of 35S-X-SH2-GST (X = Src, Abl, Grb2, p85-N, p85-C, Syp-N, and PLCγ-C domains) to immobilized PDGF receptor kinase domain was performed in a Millipore filter plate (0.45 mM PDVF) in 20 mM Tris buffer (pH 7.5), 150 mM NaCl, 10 mM mgCl2, and 0.1% triton. The assay was conducted at room temperature for 30 minutes while continuously inverting the plate.

Inhibition of DNA Synthesis as Monitored by 3H- Thymidine Uptake
DNA synthesis occurs when a cell is exposed to Platelet Derived Growth Factor (PDGF) . For PDGF- induced DNA synthesis to occur, c-SRC or another member of the SRC gene family is required. The ability of the SRC SH2 inhibitors of the present invention to block
PDGF-stimulated DNA synthesis can be assessed using the protocol set forth below.
Swiss 3T3 cells were grown in 12-well plates for 3 days to approximately 50% confluency. The growth media was removed and replaced with 1.0 mL/well of assay buffer (Dulbecco's Modified Eagle Medium containing 0.2% Bovine Serum Albumin), and incubated for 24 hours to arrest growth.
Test compounds (5 μL) were add at 100 times their final concentration. Methyl sulfoxide was used as a control and levels in all wells are kept under 1.0% of
DMSO. Cells were then stimulated with growth factor (PDGFbb or Fetal Bovine Serum), and allowed to incubate another 24 hours.
During the final 2 hours of treatment, 5 uL of 0.1 μCi/μL 3H-thymidine was added to each well (final = 0.5 μCi/well)
After incubation the medium was removed by aspiration, and each well was washed twice with ice- cold phosphate buffered saline (0.5 mL/wash) . 0.5 mL ice-cold 5% trichloroacetic acid was added to each well and incubated on ice for a minimum 10 minutes. The trichloroacetic acid solution was removed and each well was washed twice with 0.5 mL ice-cold trichloroacetic acid, and then once with ice-cold water (0.5 mL) . 0.5 mL of 2% Sodium Dodecyl Sulfate was added to each well to solubilize the cells and allowed to incubate at room temperature for 10-15 minutes. The solubilized cells were transfered to 20 mL scintillation vials. Each well was washed with 0.5 mL of water and combined with the corresponding scintillation vial. 10 mL of
Ready-Gel scintillation cocktail was added to each vial and the vials were then counted in a scintillation counter. Results are shown as percent of 3H-thymidine uptake relative to control in Table 4 below.
