Description

Technical Field

[0001] This invention belongs to the field of biomedical technology and relates to a compound that inhibits the activity of phosphatidylinositol-3-kinase γ isoform, its preparation method and application. Background Technology

[0002] Phosphatidylinositol-3-kinase (PI3K) is a family of lipases that phosphorylate phosphatidylinositol at the 3'-OH group of the plasma membrane. It is involved in multiple intracellular signaling pathways and plays an important role in normal physiology and disease development. PI3K can be divided into three classes (I, II, and III), each with different functions and structures. Class I PI3K is the most extensively studied, and it is further divided into four subtypes: PI3Kα, PI3Kβ, PI3Kδ, and PI3Kγ.

[0003] Phosphatidylinositol-3-kinase γ (PI3Kγ) acts as a second messenger in vivo and participates in various cellular physiological activities, such as cell survival, proliferation, and metabolism. PI3Kγ is highly expressed in the hematopoietic system, making it an ideal drug target for the treatment of hematological malignancies and immune-related diseases. In in vivo experiments, normal mice were able to survive and be fertile regardless of whether PI3Kγ expression was knocked out or PI3Kγ kinase activity was lost, indicating that inhibition of PI3Kγ may have low toxicity [Science, 2000, 287(5455), 1040-1046].

[0004] Previous studies have confirmed that chronic inflammation can participate in various pathological processes of cancer occurrence, growth, and metastasis, and tumor-associated inflammation has been considered the seventh characteristic of tumors. Studies have shown that PI3Kγ is one of the key subunits regulating tumor-associated inflammation, and is mainly highly expressed on inflammatory cells; PI3Kγ activation can lead to the aggregation of macrophages and neutrophils in the tumor stroma, and plays a central regulatory role in the chemokine-induced leukocyte migration process [Immunology, 2002, 105(2), 125-136.]. Studies on PI3Kγ mice have found that PI3Kγ has important regulatory effects on the chemotaxis of neutrophils and macrophages and the activation of T cells. Knocking out the PI3Kγ gene can inhibit the aggregation and activation of neutrophils, and at the same time, it can damage the function of T lymphocytes and macrophages. Therefore, PI3Kγ is considered an effective target for the treatment of inflammatory diseases [Nephron, 2002, 91(2), 262-269.].

[0005] Studies have found that PI3Kγ is highly expressed in various tumors, such as multiple myeloma (MM), liver cancer, and pancreatic ductal carcinoma (PDAC) [Blood, 2010, 116(9), 1460-1468]. PI3Kγ expression can promote the growth of malignant tumors and prevent T cell-mediated tumor death by promoting macrophage migration and regulating the polarization of macrophages, neutrophils, and lymphocytes in vitro and in vivo [Cancer Cell, 2011, 19(6), 715-727]. In vitro and in vivo experiments showed that inhibition of PI3Kγ activity reduced MM proliferation, inhibited MM cell adhesion and migration, and promoted apoptosis of primary MM cells [Blood Cancer Journal, 2017, 7(3), e539]. Furthermore, in clinical models of malignant tumors treated with doxorubicin (DOX), PI3Kγ inhibitors can limit tumor growth while preventing DOX-induced cardiotoxicity, thereby improving survival [Circulation, 2018, 138(7), 696-711]. In addition, inhibition of pulmonary PI3Kγ can treat complex multicellular diseases characterized by adaptive T-cell activation in lung tissue and subsequent granulocyte influx and activation, such as asthma and COPD [Biochim Biophys Acta, 2015, 1851(6), 882-897]. In addition, since the PI3Kγ subtype is specific in immune tissues, it can be used to treat immune diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) by inhibiting the biological activity of PI3Kγ [Journal of Medicinal Chemistry, 2012, 55(20), 8559-8581].

[0006] In summary, these findings reveal the crucial role of PI3Kγ signaling inhibition in immune responses, thus providing a highly selective phosphatidylinositol-3-kinase γ subtype inhibitor with significant application value in the treatment of various diseases, including cancer, respiratory diseases, and immune disorders.

[0573] Experimental Methods: This experiment employed the ADP-Glo ​​lipid kinase assay method from Promega. The lipid kinase PI3Kα / β / γ / δ undergoes a catalytic reaction in the presence of a 1:3 mixture of substrate phosphoinositol-4,5-bisphosphate (PIP2) and apoliposide phosphatidylserine (PS) (PIP2:3PS) and ATP. ATP is converted to ADP. The activity of the lipid kinase is characterized by measuring the ADP content in the reaction, and the half-maximal inhibitory concentration (IC50) of the compound inhibiting the activity of PI3Kα / β / γ / δ kinases is determined. 50 .

[0574] The specific experimental procedure is as follows:

[0575] The kinase reaction was performed in a white 96-well plate. 2 μL of the compound of the present invention at different concentrations diluted with ddH2O containing 1% DMSO was added to each well. For the positive control wells, 2 μL of ddH2O containing 1% DMSO was added. Then, 2 μL of 0.1–2 nM PI3K kinase solution diluted with 5× kinase buffer (HEPES 250 mM, MgCl2 15 mM, NaCl 250 mM, BSA 0.05%) was added to each well. For the negative control wells, 2 μL of 5× kinase buffer was added. 4 μL of 50 μM substrate PIP2:3PS prepared with 10× dilution buffer and ddH2O was added to all wells. Finally, 2 μL of 50–100 μM ATP solution diluted with water was added to start the reaction. After reacting at room temperature for 90–120 min, 10 μL of ADP-Glo ​​Reagent (containing 10 mM MgCl2, MgCl2, NaCl, BSA 0.05%) was added to each well. The chemiluminescence value was measured using a Varioskan LUX microplate reader after reacting with MgCl2 at room temperature for 60 min to remove excess ATP. Then, 20 μL of kinase detection reagent was added to each well, and the reaction was carried out at room temperature in the dark for 20 min.

[0576] Experimental data processing method: % inhibition rate = 100 - [(test compound value - negative control value)] / (positive control value - negative control value) × 100. The IC50 was calculated using a four-parameter nonlinear logic formula to fit different concentrations and corresponding percentage inhibition rate data. 50 Values. Results are shown in Table 1 (Note: "-" indicates no detection).

[0583] Raw264.7 cell line (Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences, #TIB-71) was cultured in RPMI 1640 medium (Invitrogen #11875093) containing 10% fetal bovine serum (FBS) (Gibco #10091148) and 1% penicillin and streptomycin (P / S (Invitrogen #15140122)) at 37°C and 5% CO2. Cells were collected before the experiment, counted, and seeded into 96-well cell culture plates at a density of 60,000 cells / 45 μL / well using RPMI-1640 medium without FBS. Cells were incubated overnight at 37°C and 5% CO2. After 18 hours of serum starvation, 45 μL of pre-prepared compound solutions of different concentrations were added to the cells to obtain a final DMSO concentration of 0.2%, and the cells were incubated at 37°C and 5% CO2 for 60 minutes. Cells were then stimulated for 5 minutes with 25 nM C5a solution (R&D System, #2150-C5 / CF) in the presence of the compound. The culture medium was aspirated, and 50 μL / well of lysis buffer was added. The cells were shaken at room temperature for 45 minutes, and then 16 μL / well of the lysate was transferred to a 384-well plate. A solvent control well was prepared, with no compound added. Premixed Phospho-AKT antibody reagent (Cisbio, #64AKSPEG) was added to each well at a density of 4 μL / well. The plate was centrifuged at 1000 rpm for 1 minute at room temperature, then incubated at 22°C for 4 hours, and read using an Envision microplate reader.

[0584] Experimental data processing method: % Inhibition rate = 100 - (Test compound value / Solvent control value) × 100. GraphPad Prism was used to fit different concentrations and corresponding inhibition rate data to a four-parameter nonlinear logic formula to calculate the IC50. 50 The values ​​are shown in Table 2.

[0587] Test Example 3 - Efficacy testing of the compound in a syngeneic mouse tumor model

[0588] Experimental subjects: Female Balb / c mice aged 6-8 weeks.

[0589] Experimental methods:

[0590] 1) CT-26 tumor cells were placed in 1640 medium supplemented with 10% heat-inactivated fetal bovine serum, 100 U / mL penicillin, and 100 μg / mL streptomycin, and cultured at 37°C in air containing 5% CO2. The tumor cells were passaged twice a week as usual, and cells growing in the exponential growth phase were harvested and counted for tumor inoculation.

[0591] 3) CT-26 tumor cells obtained from culture were subcutaneously inoculated on the right side of mice, with approximately 5 × 10⁶ cells per mouse. 5 A 26-gauge needle was used for injection when the tumor volume reached approximately 100 mm. 3 Thirty-two mice were randomly divided into four groups of eight mice each, based on tumor volume (body weight could also be considered): a control group, a PD-1 antibody group (PD-1 antibody purchased from Bioxcell, CAT No. BE0146), a compound group (Example 25), and a combination therapy group of the compound (Example 25) and PD-1 antibody. The administration methods for each group were as follows:

[0592] Control group: Orally administered normal saline once a day, sodium chloride concentration 0.9%, administration volume 10 mL / kg.

[0593] PD-1 antibody group: PD-1 antibody was injected intraperitoneally twice a week, with each injection dose of 10 mg / kg.

[0594] Compound group: The compound of Example 25 was administered orally once daily at a dose of 10 mg / kg.

[0595] The combination therapy group of the compound and the PD-1 antibody: The compound of Example 25 was administered orally once a day at a dose of 10 mg / kg, and the PD-1 antibody was injected intraperitoneally twice a week at a dose of 10 mg / kg each time.

[0596] During the experiment, animal care and use were conducted in accordance with the guidelines of the American Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC, accreditation number 001516). Morbidity and mortality were assessed daily after grouping. General health status of mice was assessed daily throughout the experimental phase. During routine monitoring, any effects of treatment on normal behavior, such as activity level, food and water consumption, weight gain / loss (measured daily), eye / hair pads, and any other abnormal effects, were examined. Any observed clinical symptoms or unexpected deaths were recorded based on the number of animals in each subset. Tumor volume was measured twice weekly in two dimensions using calipers, and the volume was expressed in mm using the following formula. 3 This means: V = 0.5a × b 2 , where a and b are the long and short diameters of the tumor, respectively. When the tumor volume in mice exceeds 2000 mm... 3 Euthanasia was performed at the time, and the tumor-suppressing effects in each group were observed. Figure 1 Note: In the experiment, once the tumor volume of the animals reached the maximum allowable value, they were euthanized as required. There were no surviving animals in the compound group, control group, and PD-1 antibody group on days 12, 14, and 16, respectively.
