This is the § 371 U.S. National Stage of International Application No. PCT/KR2018/002164, filed Feb. 22, 2018, which in turn claims the benefit of Korean Patent Application No. 10-2017-0023393, filed Feb. 22, 2017, which is incorporated by reference herein in its entirety.
The present invention relates to a pyrrolo-pyrimidine derivative compound, a preparation method therefor, and a pharmaceutical composition comprising the same compound as an effective ingredient for preventing or treating a protein kinase-related disease.
Protein kinase is an enzyme that catalyses the reaction to transfer the terminal phosphate group of adenosine triphosphate (ATP) to a specific residue of protein (tyrosine, serine, threonine), and is involved in signals that regulate cell activation, growth, and differentiation according to extracellular mediators and environmental changes.
Inappropriately high protein kinase activity is directly or indirectly involved in various diseases resulting from abnormal cellular functions. For example, mutation, over-expression or failure of appropriate regulatory mechanism of kinases involved in inappropriate enzyme activity, or over-synthesis or deficiency of factors involved in upstream or downstream signal transduction of cytokines or kinases can cause disease. Therefore, selective inhibition of kinase activity can be a beneficial target for the development of new drugs for the treatment of disease.
Brain cancer is a general term for primary brain cancer that occurs in the brain tissue and the cerebral meninges surrounding the brain and secondary brain cancer that has metastasized from the skull or other parts of the body. Such brain cancer is distinguished from other cancers developed in other organs in many aspects. First, cancers developed in lung, stomach and breast are limited in one or two types of cancer for each organ and their properties are the same or similar. However, many different types of cancers can be developed in the brain. For example, polymorphic glioblastoma, malignant glioma, lymphoma, blastoma, and metastatic tumor can be developed in the brain.
Parkinson's disease is the result of chronic progressive degeneration of neurons, but the cause has not been fully disclosed yet. Although the major causes are unknown, Parkinson's disease is characterized by the degeneration of dopaminergic neurons in the substantia nigra (SN). The substantia nigra is a part of the lower brain or the brainstem that helps the regulation of unconscious movement. Dopamine deficiency in the brain caused by loss of these neurons is known to cause observable symptoms. Clinically, the main symptoms of Parkinson's disease are resting tremor, rigidity, bradykinesia, and postural instability. Not only the MAO-B inhibitor selegiline and the COMT inhibitor entacapone but also levodopa, dopamine agonists (for example, rotigotine, pramipexole, bromocryptine, ropinirole, cabergoline, pergolide, apomorphine and lisuride), anticholinergic drugs, NMDA antagonists and β-blockers are used as medications for relieving symptoms relating to motion. Most of these drugs are involved in dopamine and/or choline signal transduction, by which they affect typical motion dysfunction symptoms of Parkinson's disease (Patent Reference 1: Korean Patent Publication No. 10-2009-0117830).
LRRK2 (leucine-rich repeat kinase-2) is a protein belonging to leucine-rich repeat kinase family, which is composed of 2527 amino acids with high interspecies similarity. Characteristically, it contains both GTPase activity and serine-threonine kinase activity in one protein. The expressed LRRK2 is observed in various organs and tissues including the brain, and is known to exist in cytoplasm or cell membrane and mitochondrial outer membrane at the cellular level. Currently, studies on in vivo functions of LRRK2 are actively under-going. LRRK2 has 5 functionally important domains which are involved in self-active regulation by autophosphorylation and cell function regulation by protein interaction and enzymatic action. Particularly, it is known that chaperone machinery, cytoskeleton arrangement, protein translational machinery, synaptic vesicle endocytosis, mitogen-activated protein kinases signaling cascades and ubiquitin/autophageprotein degradation pathways are regulated by LRRK2.
Parkinson's disease occurs sporadically in most cases, but 5-10% of the patients have family history. From the studies with the samples of these patients, the locations of PARK 1-16 genes were identified, among which a few locations have been confirmed to have mutations to cause Parkinson's disease. The known causing genes of Parkinson's disease that cause Parkinson's disease by mutation are parkin, PINK1, DN-1, α-synuclein and LRRK2 (leucine-rich repeat kinase 2), etc. Among them, the said LRRK2 gene was first reported in 2004 as a dominant gene of a homologous chromosome like α-synuclein. Patients with Parkinson's disease caused by LRRK2 mutation display very similar symptoms to patients with sporadic Parkinson's disease, unlike patients with Parkinson's disease caused by mutations of other genes. LRRK2 mutation is observed not only in those Parkinson's disease patients who have family history but also in 1-2% of sporadic Parkinson's disease patients. Thus, identification of the pathogenesis of Parkinson's disease by mutation of this gene would be very helpful in understanding the pathogenesis of Parkinson's disease and in the development of therapeutic agents.
LRRK2 is known to be involved in mild cognitive impairment associated with Alzheimer's disease, L-Dopa induced dyskinesia, CNS disorder associated with neuronal progenitor differentiation, cancer such as brain cancer, kidney cancer, breast cancer, prostate cancer, blood cancer, lung cancer and acute myelogenous leukemia, papillary kidney and thyroid carcinoma, multiple myeloma, amyotrophic lateral sclerosis, rheumatoid arthritis and ankylosing spondylitis. Therefore, a compound or a composition that is effective in regulating LRRK2 activity can provide therapeutic effects on neurodegenerative disease, CNS disorder, cancer, acute myelogenous leukemia and multiple myeloma, and inflammatory disease.
In the course of our study on a compound capable of inhibiting the activation of protein kinases, the present inventors found that a pyrrolo-pyrimidine derivative compound was not only able to inhibit the expressions of LRRK2 and various protein kinases significantly but also able to inhibit those cell lines expressing brain cancer and Parkinson's disease, leading to the completion of the present invention.

The following experiment was performed to evaluate the inhibitory activity of the compounds of Examples 1˜137 against LRRK2 kinase.
First, a recombinant LRRK2 kinase (Signal Chem, Richmond, BC, Canada), 0.2 ug/ul LRRKtide (Signal Chem, Richmond, BC, Canada) and 25 μmol/L ATP (Invitrogen, Carlsbad, Calif.) were added to kinase reaction buffer (40 mmol/L Tris-HCl, 10 mmol/L MgCl2 and 0.1 μg/μL BSA (bovine serum albumin)), which was loaded in a 384-well plate.
Next, the compounds of Examples 1˜137 were added thereto at the final concentrations of 50 uM, 5 uM, 500 nM, 50 nM, 5 nM, 500 pM, 50 pM, 5 pM, and 0.5 pM respectively, followed by reaction in a 30° C. incubator for 2 hours. Upon completion of the reaction, an equal amount of Kinase-Glo (Promega, Madison, Wis.) solution was added thereto, followed by reaction for 40 minutes. A detection solution was added thereto, followed by further reaction at room temperature for 30 minutes. Then, IC50 of kinase was calculated by measuring the amount of luciferase using a microplate ELISA reader (Bio-Tek).
The calculated IC50 values of kinase were sorted as follows and presented in Table 6 below:
Grade A: less than 10 nM,
Grade B: 10˜100 nM, and
Grade C: more than 100 nM.
To evaluate the activity of the pyrrolo-pyrimidine derivative compound compounds of the present invention to inhibit phosphorylation in LRRK2 expressing cell line, the following experiment was performed. Particularly, the inhibition of phosphorylation by the compounds of Examples 32, 33, 34, 35, 36, 47, 49, 50, 52, 94, 95 and 96 in NIH-3T3 cell line known as a cell line expressing LRRK2 was investigated.
First, NIH-3T3 cell line was seeded in a 12-well plate at the density of 1×105/cells/1 ml/well, and the cells were allowed to attach the plate for one day. Each compound of Example 32, 33, 34, 35, 36, 47, 49, 50, 52, 94, 95 or 96 was added thereto at the final concentration of 100 nM and DMSO was added thereto at the concentration of 0.1%, followed by culture in a 37° C. CO2 incubator for 24 hours. The culture medium was discarded and the plate was washed with PBS twice. 2× sample buffer (62.5 mM Tris-HCl pH 6.8, 5% SDS, 10% Glycerol, 5% beta-mercaptoethanol, 0.02% Bromophenol blue) was added to the plate (100 μl/well) and then cells were recovered. The cells were left at 75° C. for 5 minutes, followed by Western blotting.
Western blotting was performed as follows. The cells were loaded in Mini-PROTEAN® TGX™ Precast Gels (15 μl/well), followed by electrophoresis (10 minutes at 85 V, 50 minutes at 110 V). Then, protein was transferred onto PVDF membrane (18 hours at 35 V). The membrane was blocked with 5% skim milk (1 hour at room temperature), to which the primary antibody (p-LRRK2, LRRK2 or GAPDH) was added, followed by reaction at 4° C. for 18 hours. The primary antibody was washed with TBST buffer and then the secondary antibody (goat anti-rabbit IgG-HRP) was added thereto, followed by reaction at room temperature for 2 hours. Upon completion of the reaction, the membrane was washed with TBST buffer. The membrane was reacted with SuperSignal™ West Pico Chemiluminescent Substrate, followed by detection with LAS4000.

The inhibition of phosphorylation by the compounds of Examples 32, 33, 36, 47, 49, 94 and 95 in 448T, another brain tumor patient derived cell line, was also examined. The results in NCC01 cell line are shown in
Particularly, NCC01 cells line and 448T cell line (Samsung Medical Center, Seoul, Korea) were seeded in 60 mm dishes at the density of 0.75˜1×106, and the cells were allowed to attach the dish for one day. Each compound of the present invention was added thereto at the final concentration of 100 nM, followed by culture in a 37° C. CO2 incubator for 24 hours. The culture medium was collected to recover the cells. 30˜50 μL of RIPA buffer (50 mM Tris-HCl pH 7.5, 150 mM NaCl, 1% sodium deoxycholate, 0.1% SDS, 1% Triton X-100) containing protease inhibitor (Roche, 11836153001) and phosphatase inhibitor (GenDEPOT, P3200-001) was added to the cells. The mixture was placed on ice, followed by vortexing three times every 10 minutes. Centrifugation was performed (13000 rpm, 4° C., 20 minutes) and the supernatant was transferred. Protein concentration was measured by BCA assay, and 5× sample buffer (1M Tris-HCl pH 6.8, 10% SDS, 50% Glycerol, 5% beta-mercaptoethanol, 1% Bromophenol blue) was added thereto (final concentration of sample buffer: 1×), which stood at 75° C. for 5 minutes, followed by Western blotting.
Western blotting was performed as follows. The cells were loaded in Gel (20 μg/well), followed by electrophoresis (1 hour at 100 V). Then, protein was transferred onto PVDF membrane (100 minutes at 250 mA). The membrane was blocked with 5% skim milk (1 hour at room temperature), to which the primary antibody (p-LRRK2, LRRK2 or beta-actin) was added, followed by reaction at 4° C. for 18 hours. The primary antibody was washed with TBST buffer (10 minutes, 6 times) and then the secondary antibody (goat anti-rabbit IgG-HRP) was added thereto, followed by reaction at room temperature for 1 hour. Upon completion of the reaction, the membrane was washed with TBST buffer (10 minutes, 6 times). The membrane was reacted in GE ECL plus solution, followed by detection with X-ray film.
