The invention relates to a novel class of 2,4-diamino-6,7-dihydro-5H-pyrrolo[2,3]pyrimidine derivatives that inhibit Focal Adhesion Kinases (FAK/Pyk2), to a process for their preparation, and to a composition thereof, as well as to use of the compounds for the inhibiting FAK and/or Pyk2 and method for the treatment of a FAK and/or Pyk2 mediated disorder or disease, for example, a proliferative disorder or disease.
FAK (Focal Adhesion Kinase) is a nonreceptor tyrosine kinase which transduces signaling from a group of stimuli (e.g., integrins, cytokines, chemokines, and growth factors) to control a variety of cellular pathways and processes, including cell proliferation, migration, morphology, and cell survival. FAK is activated by FAC (focal adhesion complex)-associated growth factors and integrins. The binding to integrins of EMC (extracellular matrix) leads to the activation of FAK. The activation of FAK can be further enhanced by co-stimulation of the growth factors by ECM associated growth factors, such as bFGF, EGF or PDGF. Focal adhesion complex assembly and disassembly are essential for cell attachment and movement. FAK doesn't phosphorylate other proteins. However, activated FAK autophosphorylates and binds Src kinase which in turn phosphorylate other sites of FAK and other FAK binding proteins such as Cas and paxillin. Phosphorylated FAK provides the docking site for mediators of multiple signaling events and consequently involves in the regulation of cell growth and survival through activation of PI3K/Akt/mTOR and Grb2/SOS/RAS/Raf/MEK/ERK pathways. Overexpression of FAK has been associated with malignancy in a variety of cancers. Inhibition of FAK has been shown the inhibition of tumor growth in different cancer cells (Beviglia et al 2003, BioChem J. 373: 201-210, Smith et al 2005, Melanoma Res. 15:357-362, Haider et al 2005, Clin. Cancer Res. 11: 8829-8836, van Nimwegen et al 2005, Cancer Res. 65:4698-4706, Mitra et al 2006, Oncogene 25: 4429-4440). However, inhibition of FAK in normal human fibrolasts or immortalized mammary cells didn't cause loss of attachment or apoptosis (Xu et al 1996 Cell Growth and Diff. 7: 413-418). Furthermore, loss of FAK activity (reconstitution of FAK−/−cells with kinase-dead FAK) reduced growth of v-Src tumors in mice and decreased angiogenesis. Therefore, Inhibition of FAK is a potential therapy for the treatment of hyper-proliferative diseases such as cancers.
Pyk2 is the only member of the FAK family with 48% amino acid identity. Although the role of Pyk2 in tumorigenesis is not well-established yet, there is some evidence that Pyk2 plays a compensatory role FAK knockout mouse model. Therefor, dual inhibition of FAK and Pyk2 may considerably augment the anti-angiogenic effect.

The novel features of the invention are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized.
While preferred embodiments of the present invention have been shown and described herein such embodiments are provided by way of example only. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. Those ordinary skilled in the art will appreciate that numerous variations, changes, and substitutions are possible without departing from the invention. It is intended that the following claims define the scope of aspects of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.
The section headings used herein are for organizational purposes only and are not to be construed as limiting the subject matter described. All documents, or portions of documents, cited in the application including, without limitation, patents, patent applications, articles, books, manuals, and treatises are hereby expressly incorporated by reference in their entirety for any purpose.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which the claimed subject matter belongs. All patents, patent applications, published materials referred to throughout the entire disclosure herein, unless noted otherwise, are incorporated by reference in their entirety. In the event that there is a plurality of definitions for terms herein, those in this section prevail. Where reference is made to a URL or other such identifier or address, it is understood that such identifiers can change and particular information on the internet can come and go, but equivalent information can be found by searching the internet or other appropriate reference source. Reference thereto evidences the availability and public dissemination of such information.
It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of any subject matter claimed. In this application, the use of the singular includes the plural unless specifically stated otherwise. It must be noted that, as used in the specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise. It should also be noted that use of “or” means “and/or” unless stated otherwise. Furthermore, use of the term “including” as well as other forms, such as “include”, “includes”, and “included” is not limiting. Likewise, use of the term “comprising” as well as other forms, such as “comprise”, “comprises”, and “comprised” is not limiting.
Definition of standard chemistry terms may be found in reference works, including Carey and Sundberg “ADVANCED ORGANIC CHEMISTRY 4TH ED.” Vols. A (2000) and B (2001), Plenum Press, New York. Unless otherwise indicated, conventional methods of mass spectroscopy, NMR, HPLC, IR and UV/Vis spectroscopy and pharmacology, within the skill of the art are employed. Unless specific definitions are provided, the nomenclature employed in connection with, and the laboratory procedures and techniques of, analytical chemistry, synthetic organic chemistry, and medicinal and pharmaceutical chemistry described herein are those known in the art. Standard techniques can be used for chemical syntheses, chemical analyses, pharmaceutical preparation, formulation, and delivery, and treatment of patients. Reactions and purification techniques can be performed e.g., using kits of manufacturer's specifications or as commonly accomplished in the art or as described herein. The foregoing techniques and procedures can be generally performed of conventional methods well known in the art and as described in various general and more specific references that are cited and discussed throughout the present specification. Throughout the specification, groups and substituents thereof can be chosen by one skilled in the field to provide stable moieties and compounds.
Where substituent groups are specified by their conventional chemical formulas, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left. As a non-limiting example, CH2O is equivalent to OCH2.
Unless otherwise noted, the use of general chemical terms, such as though not limited to “alkyl,” “amine,” “aryl,” are equivalent to their optionally substituted forms. For example, “alkyl,” as used herein, includes optionally substituted alkyl.
The compounds presented herein may possess one or more stereocenters and each center may exist in the R or S configuration, or combinations thereof. Likewise, the compounds presented herein may possess one or more double bonds and each may exist in the E (trans) or Z (cis) configuration, or combinations thereof. Presentation of one particular stereoisomer, regioisomer, diastereomer, enantiomer or epimer should be understood to include all possible stereoisomers, regioisomers, diastereomers, enantiomers or epimers and mixtures thereof. Thus, the compounds presented herein include all separate configurational stereoisomeric, regioisomeric, diastereomeric, enantiomeric, and epimeric forms as well as the corresponding mixtures thereof. Techniques for inverting or leaving unchanged a particular stereocenter, and those for resolving mixtures of stereoisomers are well known in the art and it is well within the ability of one of skill in the art to choose an appropriate method for a particular situation. See, for example, Fumiss et al. (eds.), VOGEL'S ENCYCLOPEDIA OF PRACTICAL ORGANIC CHEMISTRY 5.sup.TH ED., Longman Scientific and Technical Ltd., Essex, 1991, 809-816; and Heller, Acc. Chem. Res. 1990, 23, 128.
The terms “moiety”, “chemical moiety”, “group” and “chemical group”, as used herein refer to a specific segment or functional group of a molecule. Chemical moieties are often recognized chemical entities embedded in or appended to a molecule.
The term “bond” or “single bond” refers to a chemical bond between two atoms, or two moieties when the atoms joined by the bond are considered to be part of larger substructure. The term “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted alkyl” means either “alkyl” or “substituted alkyl” as defined below. Further, an optionally substituted group may be un-substituted (e.g., CH2CH3), fully substituted (e.g., CF2CF3), mono-substituted (e.g., CH2CH2F) or substituted at a level anywhere in-between fully substituted and mono-substituted (e.g., CH2CHF2, CF2CH3, CFHCHF2, etc). It will be understood by those skilled in the art with respect to any group containing one or more substituents that such groups are not intended to introduce any substitution or substitution patterns (e.g., substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups, potentially ad infinitum) that are sterically impractical and/or synthetically non-feasible. Thus, any substituents described should generally be understood as having a maximum molecular weight of about 1,000 daltons, and more typically, up to about 500 daltons (except in those instances where macromolecular substituents are clearly intended, e.g., polypeptides, polysaccharides, polyethylene glycols, DNA, RNA and the like).
As used herein, C1-Cn, includes C1-C2, C1-C3 . . . C1-Cn. By way of example only, a group designated as “C1-C4” indicates that there are one to four carbon atoms in the moiety, i.e. groups containing 1 carbon atom, 2 carbon atoms, 3 carbon atoms or 4 carbon atoms, as well as the ranges C1-C2 and C1-C3. Thus, by way of example only, “C1-C4 alkyl” indicates that there are one to four carbon atoms in the alkyl group, i.e., the alkyl group is selected from among methyl, ethyl, propyl, iso-propyl, n-butyl, isobutyl, sec-butyl, and t-butyl. Whenever it appears herein, a numerical range such as “1 to 10” refers to each integer in the given range; e.g., “1 to 10 carbon atoms” means that the group may have 1 carbon atom, 2 carbon atoms, 3 carbon atoms, 4 carbon atoms, 5 carbon atoms, 6 carbon atoms, 7 carbon atoms, 8 carbon atoms, 9 carbon atoms, or 10 carbon atoms.
The terms “heteroatom” or “hetero” as used herein, alone or in combination, refer to an atom other than carbon and hydrogen. Heteroatoms are independently selected from among oxygen, nitrogen, sulfur, phosphorous, silicon, selenium and tin but are not limited to these atoms. In embodiments in which two or more heteroatoms are present, the two or more heteroatoms can be the same as each another, or some or all of the two or more heteroatoms can each be different from the others.
The term “alkyl” as used herein, alone or in combination, refers to an optionally substituted straight-chain, or optionally substituted branched-chain saturated hydrocarbon monoradical having from one to about ten carbon atoms, more preferably one to six carbon atoms.

After the addition was over, the reaction mixture was heated at 100° C. for 1-12 hours. Most of phosphoryl trichloride was removed under reduced pressure and the residue was basified by aqueous sodium bicarbonate. The aqueous phase was extracted with ethyl acetate, and the organic extracts were combined, washed by brine, dried over anhydrous sodium sulfate, evaporated and purified by silica gel chromatography to afford the product 2-(2,4,6-trichloropyrimidin-5-yl)acetates (iii).

Biochemical Assay for FAK/Pyk2 Activity
GST-tagged FAK was purchased from Invitrogen (PV3832). GST-tagged PYK2 was purchased from Invitrogen (PV4567). The activity of FAK/PYK2 was measured by monitoring the phosphorylation of a fluorophore labeled ULight-poly Glu, Ala, Tyr (1:1:1) peptide substrate from Perkin Elmer (TRF0101) in the presence of ATP. The phosphorylated tyrosine residue was recognized by a LANCE Europium chelate labeled anti-phosphotyrosine (PY20) antibody from Perkin Elmer (AD0066). This brought the fluorophore and europium chelate in close proximity (>10 nm) that upon excitation at 320 nm by an Envision (PerkinElmer), energy can be transferred from the donor Europium chelate to the acceptor fluorophore. This results in the emission of light at 665 nm and can be captured by Envision. The strength of the signal was, therefore, directly proportional to the FAK/PYK2 activity.
To measure inhibitory activity of FAK/PYK2 inhibitors, compounds were first prepare as a 1 mM stock in 100% DMSO and 3-fold serial dilution was performed in a 96-well plate (Corning, 3897) to generate 12 different concentration of 100× stock. A 5 μl of 100× stock of each concentration was added to wells containing 95 μl of 1× reaction buffer (40 mM Tris, pH7.5, mM MgCl2, 1 mM DTT and 1 mM CHAPS) to generate 5× stock. Then 2 μl of 5× stock of each concentration was added to a 384 wells-OptiPlate (PerkinElmer, 6007299).
For FAK, 4 μl of 2.5 nM FAK, 1 ul of 8 μg/μl BSA and 1.5 μl of 666 nM ULight-poly Glu, Ala, Tyr (1:1:1) peptide substrate, prepared in above reaction buffer, were added to each well. The reaction was initiated by adding 1.5 μl of 33.3 μM ATP. The reaction was allowed to proceed for 120 min before being quenched with 5 μl of 40 mM EDTA stop buffer prepared in 1×LANCE detection buffer (PerkinElmer, CR97-100).
For PYK2, 5 μl of 2 nM PYK2 and 1.5 μl of 666 nM ULight-poly Glu, Ala, Tyr (1:1:1) peptide substrate, prepared in above reaction buffer, were added to each well. The reaction was initiated by adding 1.5 μl of 46.6 μM ATP. The reaction was allowed to proceed for 40 min before being quenched with 5 μl of 40 mM EDTA stop buffer prepared in 1×LANCE detection buffer (PerkinElmer, CR97-100).
Upon quenching of the reaction, 5 μl of 8 nM anti-phosphotyrosine antibody was added to each well and incubated for 60 minutes. The plate was measured using an Envision (PerkinElmer) based on the theory mentioned above.
