Description
TECHNICAL FIELD
[0001] The present application relates to a derivative and a preparation method and application thereof, in particular to a diarylpyrimidine derivative containing a fused heterocycle and a preparation method and application thereof, and belongs to the technical field of medicines. BACKGROUND
[0002] Acquired immune deficiency syndrome (AIDS) is a serious infectious disease that destroys the human immune system mainly caused by human immunodeficiency virus type 1 (HIV-1) infection. In the life cycle of HIV-1, reverse transcriptase (RT) is responsible for reverse transcription of single-stranded RNA carrying viral genetic information into double-stranded DNA, and is an optimal target for anti-AIDS drug design. As an important component of combined antiretroviral therapy (cART), non-nucleoside reverse transcriptase inhibitors (NNRTIs) inhibit the activity of HIV-1 RT through allosteric binding, have the advantages of high activity, strong selectivity, low toxicity, etc., and are a hot research direction of anti-AIDS drugs.
[0003] Etravirine (ETR) and rilpivirne (RPV) are new generation diarylpyrimidine NNRTIs. However, with their extensive use in the clinic, a variety of mutant strains resistant to ETR and RPV have emerged, such as E138A, E138K, Y181C and Y181I, etc. In addition, this type of compound has low water solubility and oral bioavailability, large oral dose, and is prone to cause more serious side effects in clinical use. Therefore, it is one of the important research fields of anti-AIDS drugs to obtain NNRTIs with high efficiency, broad-spectrum resistance and good pharmacokinetic properties through reasonable structural modification.
[0004] Chikungunya fever (CHIKF) is a mosquito-borne infectious disease caused by Chikungunya virus (CHIKV) and widely spread in the world. Clinically, it is characterized by fever, rash, bleeding, and joint pain. A small number of patients are left with persistent joint stiffness. Chikungunya fever is prone to large-scale epidemic and outbreak in areas with high mosquito density, and is one of the mosquito-borne infectious diseases that seriously affect human public health safety in the early 21st century. At present, there is no vaccine or antiviral drug available for the prevention and control of CHIKV infection, so it is urgent to develop safe and effective small molecule drugs with clinical application value to treat Chikungunya fever.

[0153] Terminology
[0154] MT-4 cells: human acute lymphoblastic leukemia cells; MTT assay: MTT is 3-(4,5-dimethylthiazol-2)-2,5-diphenyltetrazolium bromide; trade name: thiazolyl blue; DMSO: dimethyl sulfoxide.
[0155] Test principle
[0156] Since HIV-infected MT-4 cells will be cytopathic in a certain period of time (5-7 days), a proper concentration of the solution of the compound to be tested is added to the suspension of HIV-infected MT-4 cells, and after a period of time (5-7 days) of culture, the cell viability is determined by MTT assay, and the concentration of the drug that protects 50% of the cells from cytopathic effect (EC 50 ) is obtained, and the anti-HIV activity of the target compound is determined. At the same time, the concentration of the target compound that causes 50% of the uninfected HIV cells to be cytopathic (CC 50 ) is obtained. Principle of MTT assay: MTT, i.e. bromide-3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium nitrogen, can be combined with succinic acid dehydrogenase in living cells, but not with dead cells. MTT assay is a rapid enzyme assay that reflects cell viability.
[0157] Test materials and methods
[0158] (1) HIV-1 wild strain III B , single mutant strains L100I, K103N, Y181C, Y188L, E138K, and double mutant strains K103N / Y181C (RES056) and F227L / V106A, HIV-2 ROD strain: provided by the Institute of Microbiology and Immunology, Rega Institute, Leuven University, Belgium.
[0159] (2) MT-4 cells: provided by the Institute of Microbiology and Immunology, Rega Institute, Leuven University, Belgium.
[0160] (3) MTT: purchased from Sigma Company, USA.
[0161] (4) Sample treatment: the sample is dissolved in DMSO to prepare a proper concentration before use, and double distilled water is used for 5-fold dilution, and each dilution is 5 times.
[0162] (5) Positive control drugs: doravirine (DOR), nevirapine (NVP), efavirenz (EFV), and etravirine (ETV).
[0163] (6) Test method: after dilution of the sample, it is added to the suspension of HIV-infected MT-4 cells, and after a period of time, the cell viability is determined by MTT colorimetric method, and the absorbance (A) value is recorded at 590 nm in the enzyme marker instrument, and the EC 50 , CC 50 and SI are calculated.
[0164] (7) MTT staining: After incubation with the test compound for a certain period of time, 20 μL of MTT solution was added to each well, and the incubation was continued for several hours. The staining solution was then discarded, and 150 μL of DMSO was added to each well. The absorbance was then measured at 590 nm using a microplate reader.
[0165] The procedure was as follows: the compound was dissolved in DMSO or water and diluted with phosphate buffer. 3 x 10 5 MT-4 cells were preincubated with 100 μL of different concentrations of the test compound for 1 h at 37°C. Then, 100 μL of an appropriate dilution of the virus was added to the mixture, and the cells were incubated for 1 h at 37°C. After three washes, the cells were resuspended in culture medium with or without the test compound. The cells were then incubated for 7 days at 37°C in a 5% CO2atmosphere, and the original culture medium was replenished with or without the test compound on the third day after infection. Each culture condition was repeated twice. The cytopathic effect of the virus was monitored daily using an inverted light microscope. In general, the virus dilution used in this experiment caused cytopathic effect in the cells on the fifth day after infection. The inhibitory concentration of the drug was expressed as the concentration at which the drug produced 50% inhibition of the cytopathic effect of the virus while being non-toxic to the cells (EC 50 ). It is important to emphasize that when the water solubility of the compound was poor, DMSO was used to dissolve the compound. In this case, the volume ratio of DMSO to water was generally less than 10% (the final concentration of DMSO in the MT-4 cell culture medium was less than 2%). Because DMSO can affect the antiviral activity of the test compound, the antiviral activity of the test compound in the presence of DMSO was compared with the antiviral activity of the test compound in the absence of DMSO. In addition, the final concentration of DMSO (1 / 1000) was much lower than the concentration required to affect the replication of HIV-1 in MT-4 cells.
[0166] The in vitro anti-HIV activity screening data of the target compounds were provided by the Institute of Microbiology and Immunology, Rega Institute for Medical Research, University of Leuven, Belgium. All the activity data were measured in at least three independent and parallel experiments.
[0167] First, we tested the antiviral activity and cytotoxicity of all the compounds against HIV-1 wild strain and RES056 mutant strain, and HIV-2 ROD strain. As shown in Table 1, the diarylpyrimidine compounds provided by the present application containing a fused heterocycle exhibited good anti-HIV-1 wild strain activity, with an EC 50 range of 0.0018 to 0.12 μM. Among them, compound 3a (EC 50 = 0.0019 μM), 3d (EC 50 = 0.0019 μM), and 3k (EC 50=0.0019μM), 3s(EC) 50 =0.0020μM) and 3u(EC) 50 The activity of the drug at 0.0018 μM was significantly superior to all control drugs (EC). 50 =0.0032–0.13 μM); for the HIV-1RES056 mutant strain, 3k (EC) 50 =0.35μM) showed the highest antiviral activity, superior to the marketed drug NVP (EC). 50 >9.51μM), comparable to EFV (EC). 50 =0.36 μM); for HIV-2 ROD strain, the three compounds 3a, 3k, and 3r exhibited micromolar-level antiviral activity (EC). 50 =1.26–7.04 μM), significantly superior to all control drugs (which showed no antiviral activity at the tested concentrations).

[0172] Compounds exhibiting excellent antiviral activity in the initial testing were further tested for their activity against HIV-1 mutant strains L100I, K103N, Y181C, Y188L, E138K, and F227L / V106A. As shown in Table 2, compound 3k(EC... 50 =0.0019 μM) showed particularly outstanding activity against the K103N mutant strain, superior to all positive control drugs (EC). 50= 0.0030 - 5.22 μM); for mutant strains L100I, Y181C, E138K, the activities were 0.0087, 0.032 and 0.011 μM, respectively, which were superior to or equivalent to the positive control drug. Therefore, the compounds of this type have great value for research and development, and can be used as candidate drugs for the preparation of anti-HIV.

[0177] See ① Gupta DK, et al. Mar Drugs. 2014, 12(1), 115-27.
[0178] Test principle
[0179] Alamar-Blue Cell Viability Assay Kit is a kit for detecting cell proliferation by redox indicator Resazurin. Resazurin is in the oxidized state, showing blue and basically no fluorescence. When it is taken in by cells or bacteria and metabolized by enzymes, it will be converted into pink reduction product Resorufin. Resorufin can emit strong red fluorescence, and the change in cell viability can be detected by fluorescence.
[0180] Plaque assay is an experimental method for determining viral infectivity. Appropriate concentration of virus suspension is added to the layered monolayer cell culture to allow virus adsorption, and then a layer of melted agar is covered. Each virus replicates in infected cells to produce a localized focus of infection, i.e. plaque. Live cells can be seen as colorless plaques by staining with neutral red. Each plaque is produced by the replication of an infectious virion, called plaque forming unit (PFU), i.e. one plaque is equivalent to one virion. The amount of infectious virus contained in the virus suspension is expressed in terms of plaque forming units per milliliter, i.e. PFU / ml.
[0181] Test materials and methods
[0182] (1) Cell and compound preparation: BHK21 (juvenile hamster kidney) cells and SJCRH30 rhabdomyosarcoma cells (ATCCCRL-2061) were cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum (FCS) at 37°C and 5% CO2. C6 / 36 mosquito cells isolated from Aedes albopictus embryonic tissue were cultured in L-15 medium containing 10% FCS at 28°C. CHIKV-122508 (SGEHICHD 122508, provided by the Singapore Institute of Environmental Health) was multiplied in C6 / 36 cells and stored at -80°C before use. Compounds were dissolved in DMSO to a final stock concentration of 10 mM and stored at -80°C.
[0183] (2) Cell viability assay: SJCRH30 cells were seeded in 96-well cell culture plates and incubated overnight at 37°C and 5% CO2. The compound was diluted with 2% FCS and then incubated with a monolayer of SJCRH30 cells at 37°C and 5% CO2 for 24 hours. After the incubation period, the cells were washed once with phosphate-buffered saline (PBS), and 10 μL was added to each well. The reagents were then incubated at 37°C and 5% CO2 for 4 hours. A microplate reader (Tecan) was used. The fluorescence detected was read at an excitation wavelength of 570 nm and an emission wavelength of 600 nm (Switzerland). Measurements of cells treated with the compound or 0.1% DMSO solvent (control) were normalized to measurements of untreated cells. Cytotoxic concentration (CC) 50 () is defined as the treatment concentration at which a compound causes 50% of cells to become diseased.
[0184] (3) Drug inhibition study: SJCRH30 cells were seeded into 96-well plates and incubated overnight at 37°C and 5% CO2. Cells were then infected with 1 MOI (multiple of infection) of CHIKV-122508 for 1.5 hours. Subsequently, the cells were washed twice with PBS, and the desired drug concentration was added to the cells and incubated for 24 hours. The supernatant from the CHIKV-infected cells was then extracted for viral plaque assays. Three independent experiments were performed for each drug concentration group.
[0185] (4) Viral Plaque Assay: BHK cells were seeded in 24-well plates and incubated overnight at 37°C and 5% CO2. The CHIKV-treated supernatant was serially diluted 10-fold from 10¹ to 10⁶, and 100 μL of the diluted supernatant was added to the BHK cells. Incubation was performed for 1.5 hours, with shaking at 15-minute intervals during this period. After incubation, the plates were washed twice with PBS and covered with 1% carboxymethyl cellulose (CMC). The assay plates were incubated at 37°C and 5% CO2 for 3 days. The CMC was removed, and the cells were stained and fixed with 10% paraformaldehyde-1% crystal violet (Sigma-Aldrich Chemical, St. Louis, MO, USA) solution for observation and plaque counting. Viral titers were expressed as plaque-forming units (PFU) per milliliter.
[0186] The in vitro anti-CHIKV activity screening data of the target compounds were provided by the Yong Loo Lin School of Medicine, National University of Singapore. All activity data were obtained through at least three independent, parallel experiments.
[0187] First, the cytotoxicity of the compounds was tested using an Almar Blue cell viability assay kit. Compounds with cell viability exceeding 80% at a 10 μM concentration were further tested for their anti-CHIKV activity. As shown in Table 3, compounds 3b, 3g, 3j, 3k, 3q, 3r, 6a, and 9d exhibited good anti-CHIKV activity at a 10 μM concentration. In particular, compounds 3q and 3r showed inhibitory activity of 3.4-log and 3.1-log, respectively, compared to the negative control (0.1% DMSO). This is the first report of anti-CHIKV activity in diarylpyrimidine derivatives containing fused heterocycles. Given that there are currently no approved drugs specifically targeting CHIKV, these compounds have significant research and development value and can be utilized as candidate drugs for the preparation of anti-CHIKV drugs.

[0191] IV. Conclusion
[0192] The di-aryl pyrimidine derivative containing fused heterocycle provided by the present application is a series of novel compounds. As shown in Table 1, the activities of five compounds 3a, 3d, 3k, 3s and 3u against HIV-1 wild strain are obviously superior to all the control drugs; for HIV-2 ROD strain, the antiviral activities of compounds 3a, 3k and 3r are significantly superior to all the control drugs. As shown in Table 2, the activity of compound 3k against K103N mutant strain is significantly superior to all the positive control drugs. As shown in Table 3, compared with the negative control (0.1% DMSO), compounds 3q and 3r exhibit significant anti-CHIKV activity at a concentration of 10 μM. Therefore, the compounds have great value for research and development, and can be utilized and developed as candidate drugs for preparing anti-HIV and anti-CHIKV.
