Description

[Technical Field]

[0001] This invention relates to the fields of medical chemistry and medicine, and more specifically to type I PRMT inhibitor compounds, methods for preparing the same, and their applications in the field of disease treatment. [Background technology]

[0002] Protein arginine methylation is a highly abundant post-translational modification method widely present in the cytoplasm and cell nucleus. The protein arginine methyltransferase (PRMT) family are key enzymes involved in the protein arginine methylation process, primarily using S-adenosylmethionine (SAM) as a methyl group donor to methylate the nitrogen atom of the protein arginine side chain to produce S-adenosylhomocysteine ​​and methylarginine. The PRMT family includes nine types of PRMTs. Depending on the type of catalytic reaction, PRMTs can be classified into Type I (PRMT1, PRMT2, PRMT3, PRMT4, PRMT6, PRMT8), Type II (PRMT5, PRMT9), and Type III (PRMT7). Type I PRMTs are responsible for asymmetric dimethylated arginine (ADMA), Type II PRMTs are responsible for symmetric dimethylated arginine (SDMA), and Type III PRMTs are responsible for monomethylated arginine (MMA).

[0003] Numerous studies have confirmed that abnormal expression of type I PRMT is closely related to the development and progression of various diseases. For example, PRMT1 is known to play an oncogenic role in cancers such as leukemia, lung cancer, liver cancer, gastric cancer, colon cancer, breast cancer, pancreatic cancer, head and neck tumors, prostate cancer, and bladder cancer. In malignant gliomas, PRMT2 is highly expressed at the protein level and has been found to be closely associated with poor prognosis. At least a twofold increase in PRMT4 expression is observed in 70% of acute myeloid leukemia (AML) patients. PRMT6 has been found to be highly expressed in 52.6% of gastric cancer cells, and its expression level is significantly positively correlated with the level of modification of its substrate. At the same time, since type I PRMT is mainly responsible for catalyzing the asymmetric dimethylation of arginine, alterations in asymmetric dimethylation levels in vivo are closely related to cardiovascular disease, diabetes, renal failure, asthma, and chronic non-obstructive diseases. Therefore, it can be said that the abnormal expression of type I PRMT is involved in the development and progression of various diseases. In summary, developing novel PRMT inhibitor molecules is of great importance. [Overview of the Initiative] [Problems that the invention aims to solve]

[0174] Examples of biological tests Test Example 1. PRMT1 Enzyme Activity Test Method The PRMT1 enzyme activity test experiment is performed using a buffer prepared on the day, which consists of 10 mM Tirs-HCl (pH=8.0), 0.01% Tween-20, and 1 mM DTT. Using 100% DMSO, the compound is prepared to 100X, the highest inhibitor concentration ultimately required for the reaction, and then transferred to one well of a 384-well Echo plate (384-well polypropylene microplate 2.0, clear, flat-bottom, Echo-qualified), and subsequently diluted in the next well with a 3-fold dilution of 100% DMSO, and so on, until a total concentration of 10 is reached based on Precision. 100% DMSO is added to two empty wells in the same 384-well Echo plate as a control well without the compound and a control well without the enzyme. 250 nL of the compound is transferred from each well of the 384-well Echo plate to a 384-well measurement plate (384-well polypropylene storage microplate) via an Echo550 liquid handler. For control wells containing the compound and control wells without the compound, add a mixture containing the PRMT1 enzyme (15 μL) to the 384-well measurement plate. For control wells without the enzyme, add a mixture containing the test buffer (15 μL) instead. Incubate the compound with PRMT1 at room temperature for 15 minutes, then add a mixture containing 3H-SAM and peptide (10 μL) to initiate the reaction (final volume = 25 μL). The final concentrations of the components are as follows: PRMT1 0.5 nM, 3H-SAM 0.25 μM, peptide 0.1 μM, and DMSO concentration 1%. After incubation for 120 minutes, the measurement is terminated by adding non-radioactive labeled SAM (5 μL) to a final concentration of 125 μM, thereby diluting the 3H-SAM to a level where engagement with the peptide substrate is no longer detectable. Next, 25 μL of the reaction mixture from the 384-well measurement plate is transferred to a 384-well detection plate (Streptavidin FlashPlate HTS PLUS, large capacity, 384 wells). The biotinylated peptide is allowed to bind to the streptavidin surface at room temperature for at least 60 minutes. The Flashplate is then washed three times with 0.1% Tween-20 using a BioTek plate washer.The plate is read using a microwell plate counter (MicroBeta2), and the amount of 3H-labeled peptide bound to the surface of the detection plate is measured in counts / minute (cpm).

[0186] Test Example 4. RKO in Cell Western Method Seed 2,000 cells per well and 100 μL of medium in a 96-well plate (Corning #3599) coated with polylysine, at a concentration of 20,000 cells / ml. Add 500 nL of the compound to the 96-well plate. 3) Incubate the 96-well plate in a 37°C, 5% carbon dioxide incubator for 72 hours. After 3 days, remove the 96-well plate from the incubator, add 100 μL of 8% paraformaldehyde solution to each well, and leave at room temperature for 15 minutes. After 15 minutes, shake off the liquid from the plate and wash three times with phosphate buffer (1 × PBS). Shake off the liquid from the plate, add 200 μL of membrane rupture buffer (PBS with 0.1% (v / v) Tween-20 added), and incubate in a shaker for 30 minutes. After 30 minutes, shake off the liquid from the plate, add blocking buffer, and incubate at room temperature with shaking for 2 hours. Next, shake off the liquid from the plate, add blocking solution containing the primary antibody (MMA primary antibody, CST#8711S, 1:1000v / v) to the 96-well plate, and incubate overnight at 4°C with shaking. The next day, wash three times with washing solution (PBS with 0.05% (v / v) Tween-20 added), add blocking solution containing the secondary antibody (goat anti-rabbit IgG(H+L) Invitrogen#31460, 1:10000v / v), and incubate at room temperature for 2 hours. Next, wash the 96-well plate four times with washing solution. Add the TMB mixture to the 96-well plate and incubate at room temperature with shaking for 15 minutes. Next, add the stop solution and read the OD450nm on a microplate reader. Wash three times with washing solution, add 50 μL of Janus green, and incubate at room temperature with shaking for 15 minutes. Wash 10 times with water until the color disappears, add 200 μL of 0.5 M hydrochloric acid solution to each well, and incubate at room temperature for 10 minutes. Read the values ​​at OD595 nm using a Flexstation.

[0187] Calculation: First, calculate the OD450 / OD595 ratio for each well. Each plate contains six DMSO-negative control groups (ZPEs) and six 10 μM positive control groups (HPEs). The average control group ratio is used to determine the activation percentage for each test well. The compound to be tested is diluted with DMSO three times at a total of eight concentration points, with a starting concentration of 5 μM. The formula for calculating the activation percentage for each test well is as follows: Activation percentage = 100 - [(HPE ratio - specific well ratio) / (HPE ratio - ZPE ratio)] × 100
