Definitions

  • the present invention relates to a novel fused pyrimidine derivative having an inhibitory activity for FMS kinases, and a pharmaceutical composition comprising same for the prevention and treatment of diseases caused by abnormal activation of FMS kinases.
  • Protein kinases a catalyst enzyme for phosphorylation of hydroxyl groups in tyrosine, serine and threonine moieties of protein, play an important role in a growth factor signal transduction inducing growth, differentiation and proliferation on cells.
  • a signal transduction system in body should keep a balance between on and off.
  • a mutation or an overexpression of particular protein kinases collapses the signal transduction system in a normal cell, e.g., by a continuous signal transduction in body, to induce various diseases such as cancer, inflammation, metabolic disease, and brain disease.
  • Human protein kinases are estimated to exist in 518 species, about 1.7% of human whole genes, and largely divided into tyrosine protein kinases (at least 90 species) and serine/threonine protein kinases.
  • Tyrosine protein kinases may be divided into receptor tyrosine kinases which are classified into 20 subtypes of 58 species and cytoplasm/non-receptors which are classified into 10 subtypes of 32 species.
  • Receptor tyrosine kinases have domains on the cell surface for reception of growth factors, and active sites in the cytoplasm for phosphorylation of tyrosine moieties.
  • a growth factor binds to the growth factors receptor site on the cell surface of the receptor tyrosine kinase, the receptor tyrosine kinase forms a polymer and the tyrosine moieties of cytoplasm are autophosphorylated.
  • the signal transduction progresses inside nuclear by sequential phosphorylation of subfamily proteins, thereby causing transcription and synthesis of various genes that may be involved in cell growth, differentiation, proliferation and the like.
  • the protein kinases may be abnormally overexpressed or activated by the mutation and the like, which is known to induce various diseases such as cancer.
  • C-fms cellular feline McDonough sarcoma
  • FMS a kind of protein kinase, also known as CSF-1R (colony-stimulating factor- 1 receptor).
  • FMS a receptor for the macrophage colony-stimulating factor (M-CSF)
  • M-CSF macrophage colony-stimulating factor
  • RTK receptor tyrosine kinase
  • FMS Functioning to control the proliferation, survival, differentiation and migration of macrophages and osteoclasts, FMS synergizes with other proteins to enhance the regulation of the cytokine release of macrophages, and plays a pivot role in innate immunity and in the growth and function of tissues. Particularly, FMS is involved in the activation of monocytes into macrophages and the differentiation of monocytes into osteoclasts, playing a crucial role in inflammation and bone erosion.
  • M-CSF stimulates the expression of RANK (Receptor Activator of NF- ⁇ ) by binding to FMS of monocytes at an early stage of osteoclast precursors while they become bipotential and proliferate.
  • RANK Receptor Activator of NF- ⁇
  • RNAKL When expessed RANK is not bound with RNAKL, the precursors are activated into macrophages which are responsible for the release of inflammatory cytokines such as TNF-a and IL-lb.
  • cytokines such as TNF-a and IL-lb.
  • M-CSF the binding of RANKL to RANK with the help of M-CSF stimulates differentiation into osteoblasts, inducing bone erosion. It is known that the expression of FMS is blocked in the synovium of joints.
  • FMS kinases are associated with the onset of immune diseases, metabolic diseases, inflammatory diseases or cancer, and particularly, with the onset of rheumatoid arthritis, osteoporosis, Crohn's disease, arteriosclerosis, hyperlipidemia, lung cancer, breast cancer, and prostate cancer.
  • rheumatoid arthritis is an autoimmune disease that results in a chronic systemic inflammatory disorder.
  • the process involves an inflammatory response of capsule (synovium around the joints, which gradually spreads into surrounding cartilage and bones, resulting in the destruction and deformity of the joints.)
  • the fingers may suffer from boutonniere deformity of the thumb, ulnar deviation of metacarpophalangeal joints, or swan-neck deformity in the late stages of rheumatoid arthritis.
  • Rheumatoid arthritis affects about 1% of the world population, which amounts to 30 million persons with more frequent onset in women among adults with an age of 20 to 45 years.
  • the market of rheumatoid arthritis therapeutics has expanded every year, and TNF (tumor necrosis factor) blockers, non-steroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase (COX-2) inhibitors, and anti-rheumatic drugs (DMARD, disease- modifying antirheumatic drugs) share the market.
  • TNF tumor necrosis factor
  • NSAIDs non-steroidal anti-inflammatory drugs
  • COX-2 cyclooxygenase
  • DMARD anti-rheumatic drugs
  • TNF blockers include EnbrelTM (etanercept), HumiraTM (adalimumab), RemicadeTM (infliximab), and CimziaTM (certolizumab), and are often used in combination with MTX (methotrexate). Generally, these agents should only be used if methotrexate and other conventional agents are not effective.
  • rituximab is recommended if the primary prescription is not effective any more.
  • TNF blockers are used again, or a tertiary treatment with abatacept or tocilizumab plus MTX is considered.

Description

DESCRIPTION
FUSED PYRIMIDINE DERIVATIVES HAVING INHIBITORY ACTIVITY ON FMS KINASES
FIELD OF THE INVENTION
The present invention relates to a novel fused pyrimidine derivative having an inhibitory activity for FMS kinases, and a pharmaceutical composition comprising same for the prevention and treatment of diseases caused by abnormal activation of FMS kinases.
BACKGROUND OF THE INVENTION
Protein kinases, a catalyst enzyme for phosphorylation of hydroxyl groups in tyrosine, serine and threonine moieties of protein, play an important role in a growth factor signal transduction inducing growth, differentiation and proliferation on cells.
In order to maintain homeostasis in body, a signal transduction system in body should keep a balance between on and off. However, a mutation or an overexpression of particular protein kinases collapses the signal transduction system in a normal cell, e.g., by a continuous signal transduction in body, to induce various diseases such as cancer, inflammation, metabolic disease, and brain disease. Human protein kinases are estimated to exist in 518 species, about 1.7% of human whole genes, and largely divided into tyrosine protein kinases (at least 90 species) and serine/threonine protein kinases. Tyrosine protein kinases may be divided into receptor tyrosine kinases which are classified into 20 subtypes of 58 species and cytoplasm/non-receptors which are classified into 10 subtypes of 32 species. Receptor tyrosine kinases have domains on the cell surface for reception of growth factors, and active sites in the cytoplasm for phosphorylation of tyrosine moieties. When a growth factor binds to the growth factors receptor site on the cell surface of the receptor tyrosine kinase, the receptor tyrosine kinase forms a polymer and the tyrosine moieties of cytoplasm are autophosphorylated. Then, the signal transduction progresses inside nuclear by sequential phosphorylation of subfamily proteins, thereby causing transcription and synthesis of various genes that may be involved in cell growth, differentiation, proliferation and the like. At that time, the protein kinases may be abnormally overexpressed or activated by the mutation and the like, which is known to induce various diseases such as cancer.
C-fms (cellular feline McDonough sarcoma) is a member of the family of genes originally isolated from the Susan McDonough strain of feline sarcoma viruses, and codes for FMS, a kind of protein kinase, also known as CSF-1R (colony-stimulating factor- 1 receptor). FMS, a receptor for the macrophage colony-stimulating factor (M-CSF), is a class III receptor tyrosine kinase (RTK) together with Kit, Flt-3 and PDGFR, and is coded for by the cellular proto-oncogene FMS. M-CSF, also known as CSF-1, is actively expressed in RACE (rat aortic endothelial cells), and usefully used as a biomarker of the rat aortic vessel.
Functioning to control the proliferation, survival, differentiation and migration of macrophages and osteoclasts, FMS synergizes with other proteins to enhance the regulation of the cytokine release of macrophages, and plays a pivot role in innate immunity and in the growth and function of tissues. Particularly, FMS is involved in the activation of monocytes into macrophages and the differentiation of monocytes into osteoclasts, playing a crucial role in inflammation and bone erosion. In detail, M-CSF stimulates the expression of RANK (Receptor Activator of NF-κΒ) by binding to FMS of monocytes at an early stage of osteoclast precursors while they become bipotential and proliferate. When expessed RANK is not bound with RNAKL, the precursors are activated into macrophages which are responsible for the release of inflammatory cytokines such as TNF-a and IL-lb. On the other hand, the binding of RANKL to RANK with the help of M-CSF stimulates differentiation into osteoblasts, inducing bone erosion. It is known that the expression of FMS is blocked in the synovium of joints.
Also, FMS kinases are associated with the onset of immune diseases, metabolic diseases, inflammatory diseases or cancer, and particularly, with the onset of rheumatoid arthritis, osteoporosis, Crohn's disease, arteriosclerosis, hyperlipidemia, lung cancer, breast cancer, and prostate cancer.
Although the cause thereof is still not completely known, rheumatoid arthritis is an autoimmune disease that results in a chronic systemic inflammatory disorder. The process involves an inflammatory response of capsule (synovium around the joints, which gradually spreads into surrounding cartilage and bones, resulting in the destruction and deformity of the joints.) For example, the fingers may suffer from boutonniere deformity of the thumb, ulnar deviation of metacarpophalangeal joints, or swan-neck deformity in the late stages of rheumatoid arthritis.
Rheumatoid arthritis affects about 1% of the world population, which amounts to 30 million persons with more frequent onset in women among adults with an age of 20 to 45 years. The market of rheumatoid arthritis therapeutics has expanded every year, and TNF (tumor necrosis factor) blockers, non-steroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase (COX-2) inhibitors, and anti-rheumatic drugs (DMARD, disease- modifying antirheumatic drugs) share the market. . Among them, sales of TNF blockers (anti-TNF) amounted to 13.7 billion dollars in 2007, and 18 billion dollars in 2008, while the DMAR drug market gradually expanded from being valued at 2.5 billion dollars in 2007 to 3.0 billion dollars in 2008.
Disease-modifying antirheumatic drugs (DMARD) are the primary treatment for rheumatoid arthritis. They have been found to cause symptomatic improvement. Representative among biological agents for the treatment of rheumatoid arthritis are TNF blockers (anti-TNF). Commercially available TNF blockers include Enbrel™ (etanercept), Humira™ (adalimumab), Remicade™ (infliximab), and Cimzia™ (certolizumab), and are often used in combination with MTX (methotrexate). Generally, these agents should only be used if methotrexate and other conventional agents are not effective. According to the guidance of the National Institute for Health and Clinical Excellence (NICE), a combination of rituximab with MTX is recommended if the primary prescription is not effective any more. When this secondary treatment cannot further function or when an adverse effect of rituximab is anticipated, either TNF blockers are used again, or a tertiary treatment with abatacept or tocilizumab plus MTX is considered.
Although there are various DMARD agents and biological agents, formulations for oral administration have not been developed thus far. Therefore, there is a need for a formulation for oral administration with improved medicinal efficacy.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a novel fused pyrimidine derivative having inhibitory activity on FMS kinases.
It is another object of the present invention to provide a pharmaceutical composition comprising same for the prevention or treatment of diseases caused by abnormal activation of FMS kinases.
In accordance with an aspect of the present invention, there is provided a compound selected from the group consisting of a fused pyrimidine derivative of formula (I), and a pharmaceutically acceptable salt, stereoisomer, hydrate and solvate thereof:

Experimental Examples
The compounds prepared in the above Examples were assayed for pharmaceutical activity as follows.
Experimental Example 1: Assay for Inhibitory Activity against FMS Kinase
In this Experimental Example, inhibitory activities of the compounds obtained above against FMS kinase were examined using an FRET-based analysis kit (Z'-Lyte™ kinase assay-Tyr 1 peptide kit, Cat. pv3190, Invitrogen) and recombinant human FMS kinase (Cat. pv3249, Invitrogen). Each compound was diluted in 4% DMSO to a concentration of 1 μΜ, 100 nM, 50 nM, 10 nM, and 1 nM, respectively, and each dillution was plated into black bottom, 384- well plates (NUNC). FMS kinase with a concentration of 0.3 μg/mL in a mixture with Tyr 1 peptide and a kinase buffer was added to the plates in an amount of 10 per well, and ATP was added to each well at a concentration of 150 μΜ and incubated at room temperature for 1 hr in a dark condition. A developing reagent was added to the resulting solution and incubated at room temperature for 1 hr in a dark condition. After the reaction was stopped with a stop reagent, fluorescence was read on a microplate reader with a filter set of excitation wavelength 400 nm and emission wavelength 445 nm.
For a 100% inhibition control, fluorescence was measured by using 4% DMSO and a kinase buffer, instead of the test compounds and ATP, respectively. On the other hand, 4% DMSO was used, instead of the test compounds in a 0% inhibition control. Fluorescence was also detected from a 100% phosphorylation group in which 4% DMSO, a phosphor-peptide solution, and a kinase buffer were used, instead of the test compounds, Tyr 1 peptide, and ATP, respectively.
On the basis of fluorescence measurements, IC50 values were calculated using the program Excel™ of Microsoft.
Experimental Example 2: Assay with M-NFS-60 Cells
The M-NFS-60 cell line, purchased from ATCC (the American Type Culture Collection, USA), was grown in an RPMI medium [supplemented with 10% FBS, 1% penicillin/streptomycin, and 20 ng/mL of recombinant M-CSF] at 37°C in an 5% C02 incubator. Again, the M-NFS-60 cells were incubated in a serum-free medium for 24 hrs before they were seeded at a density of 2.5x104 cells in 50 μΐ, per well into 96-well plates. Subsequently, recombinant M-CSF was added at a concentration of 20 ng/mL to a 5% FBS medium, and then treated with a 10-fold serial dilution of each of the test compounds from 10 μΜ to 0.1 nM.
Cell viability was determined using an MTT [3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide] assay (CellTiter 96 Assay, Promega Cat. G3581). Cells were incubated for 2 hrs with 16 μΐ, of the dye in each well. Absorbance at 590 nm was read using a microplate reader, and IC50 values were calculated using software (GraphPad Prism 4.0). The results obtained from Experimental Examples 1 and 2 are shown in Table 2 below. Table 2
