Abstract
Description
Technical Field
[0001] This invention belongs to the field of chemical pharmaceuticals. Specifically, this invention relates to 4-methylquinazoline derivatives, their preparation methods, pharmaceutical compositions, and uses. Background Technology
[0002] Phosphatidylinositol 3-kinase (PI3K) belongs to the lipid kinase family. It is widely distributed in cells and participates in the regulation of various cellular functions, including cell proliferation, differentiation, apoptosis, signal transduction, and glucose transport. Based on differences in structure and function, PI3K can be divided into three major classes: I, II, and III. Among them, class I PI3K has been studied the most extensively, including four subtypes: α, β, γ, and δ. All of them are heterodimers composed of a regulatory subunit (p85) and a catalytic subunit (p110). PI3Kγ and PI3Kδ are mainly distributed in leukocytes, while the other two subtypes, PI3Kα and PI3Kβ, are widely distributed in various cell types. PI3K is a downstream effector of receptor tyrosine kinase (RTK) and G protein-coupled receptor (GPCR). It activates protein kinase B (AKT) by phosphorylating the corresponding phospholipids, thereby transducing various extracellular cytokine signals into the cell (e.g., Stephens et al., Current Opinion in Pharmacology, 2005, 5(4):357-365). Abnormalities in the PI3K signaling pathway are closely related to the formation and development of various diseases. Currently, four PI3K inhibitors, namely Idelalisib, Copanlisib, Alpelisib, and Duvelisib, have been approved by the FDA. In addition, several other PI3K inhibitors are in clinical trials, with indications including not only tumors but also autoimmune diseases such as psoriasis, rheumatoid arthritis, ulcerative colitis, idiopathic pulmonary fibrosis, and chronic obstructive pulmonary disease, as well as other diseases related to class I PI3K.
[0003] Therefore, the development of novel PI3K inhibitors holds promise for providing entirely new options and treatment methods for a variety of malignant diseases, including cancer. Summary of the Invention
[0004] The purpose of this invention is to provide a novel class of PI3K inhibitors, along with their preparation methods, pharmaceutical compositions, and uses. These PI3K inhibitors exhibit strong inhibitory activity against PI3K, thereby providing better preventative and / or therapeutic effects against PI3K-mediated diseases such as tumors, autoimmune diseases, kidney diseases, cardiovascular diseases, inflammation, metabolic / endocrine disorders, or neurological diseases, while reducing adverse reactions and the development of drug resistance. Furthermore, the inventors have also discovered that these inhibitors possess a certain inhibitory effect on HDAC.

[1039] Experimental Example 1: PI3Kα Kinase Activity Assay
[1040] The effects of the compounds of this invention on PI3Kα were evaluated using an in vitro kinase activity assay. A luciferase-based cryo-optical assay was used to determine the kinase activity of PI3Kα by detecting the level of ADP produced during the kinase reaction, thereby reflecting the inhibitory level of the compounds on PI3Kα kinase activity. Kinase-Glo TM The kinase activity assay kit was purchased from Promega. PI3Kα kinase and substrate PIP2 were purchased from Invitrogen. OptiPlate was used. TM -384 White 384-well plates were used for testing. All assays were performed at room temperature. Kinase buffer consisted of 50 mM Hepes (pH 7.5), 3 mM MgCl2, 100 mM NaCl, 1 mM EGTA, 0.03% CHAPS, and 2 mM DTT. PI3Kα kinase was diluted to a 6.6 nM kinase solution with kinase buffer. Substrate solution consisted of 100 μM PIP2 and 50 μM ATP. The test compound was diluted to 10 mM in 100% DMSO, and then serially diluted 3-fold in 100% DMSO to 10 different concentrations. The compound diluted in 100% DMSO was then diluted 25-fold in 1× kinase buffer. 2.5 μL of the diluted compound solution and 2.5 μL of PI3Kα kinase solution were added to each well of the 384-well plate. The reaction was initiated by adding 5 μL of substrate solution to each well, with a final reaction volume of 10 μL. The ATP concentration was 25 μM, the PIP2 concentration was 50 μM, and the PI3Kα kinase concentration was 1.65 nM. The 384-well plate was incubated at room temperature in the dark for 1 hour, followed by the addition of 10 μL of Kinase-Glo to each well. TM The reaction was terminated with reagents, incubated for 15 minutes, and then the cold light was read on an EnVision 2104 multi-label microplate reader.
[1041] The inhibition percentage is calculated based on the following formula:
[1042] Inhibition % = 100 – (max-sample RLU) / (max-min) * 100%
[1043] Where sample RLU is the cold light reading at a given compound concentration, min refers to the reading of the DMSO control, and max refers to the reading of the enzyme-free control. The IC50 of the compound is calculated using the XLfit program in Excel. 50 The values are shown in Table 1.
[1044] Experimental Example 2: HDAC1 Activity Test
[1045] The effect of the compound on HDAC1 activity was tested in vitro. Recombinant full-length HDAC1 was purchased from BPSBiosciences. 384-well plates were purchased from Perkin Elmer. The compound was dissolved in DMSO to prepare a 10 mM stock solution. Tris buffer was used as the test buffer, and both the compound stock solution and the HDAC1 stock solution were diluted to the appropriate concentrations with this buffer. The substrate solution contained trypsin and Ac peptide. In each well of the 384-well plate, 15 μL of HDAC1 solution and the diluted compound solution were added, and the plates were incubated at room temperature for 15 minutes. Then, 10 μL of the substrate solution was added, and the plates were incubated at room temperature for 1 hour. The 384-well plates were placed in a Synergy MX multi-plate reader, and the fluorescence values at an excitation wavelength of 355 nm and an emission wavelength of 460 nm were read.
[1046] The inhibition percentage is calculated based on the following formula:
[1047] Inhibition % = (max - signal) / (max - min) * 100%
[1048] Where signal is the reading at a given compound concentration, min refers to the reading for the DMSO control, and max refers to the reading for the enzyme-free control. The IC50 of the compound is calculated using the XLfit program in Excel. 50 The values are shown in Table 1.
[1049] The biological activities of PI3Kα and HDAC1 in some embodiments are presented in Table 1 as semi-quantitative results: IC 50 (A) <150nM, 150nM <IC 50 (B) <1000nM, IC 50 (C)>1000nM.

[1054] Logarithmic growth phase HGC27 (human gastric cancer cells) and HCT116 (human colorectal cancer cells) were seeded at 2000 cells / well / 100 μL in 96-well plates and cultured overnight at 37°C. Fresh culture medium containing different concentrations of the test compound and corresponding solvent controls was added to each well, with 100 μL of DMSO (final concentration <0.1%) added. The plates were then cultured at 37°C for another 72 hours. 20 μL of freshly prepared PBS solution containing 5 mg / mL MTS was added to each well and cultured for 4 hours. After mixing with a micro-shaker, the optical density (OD) was measured at a detection wavelength of 490 nm. DMSO-treated tumor cells served as the control group. The inhibition rate of the test compound on tumor cell growth was calculated using the following formula, and the IC50 was calculated according to the median effect equation. 50 :
[1055] Inhibition rate (%) = (mean OD value of control group - mean OD value of drug-treated group) / mean OD value of control group × 100%
