[0002] CN202211169562.X, September 23, 2022. TECHNICAL FIELD

[0003] The application discloses a crystal form of a quinazoline compound and a preparation method thereof, and specifically discloses a crystal form of a compound of formula (I) and a preparation method and application thereof. BACKGROUND

[0004] RAS protein is a guanine nucleotide binding protein with guanosine triphosphatase (GTPase) activity, mainly including three subtypes, KRAS, NRAS and HRAS. As a binary molecular switch for GDP / GTP cycle control, RAS protein can cycle between active GTP binding state (GTP-RAS) and inactive GDP binding state (GDP-RAS). This cycle has important regulatory functions in cells, and is closely related to cell proliferation, survival, metabolism, migration, immunity and growth.

[0005] SOS1 (English full name Son of Sevenless 1) is a kind of GEF regulating the GDP / GTP cycle of RAS protein. After the cell surface receptor is activated and combined with intracellular Grb2, Grb2 recruits SOS1 to the cell membrane, and then SOS1 catalyzes the exchange of RAS-GDP / GTP, thereby activating the downstream signal pathway. Small molecule SOS1 inhibitors combined in the catalytic site can block the binding of SOS1 and RAS protein, thereby effectively reducing the abnormal activation of the RAS downstream signal pathway in cancer cells, and playing a role in treating cancer. At present, only the SOS1 small molecule inhibitor BI-1701963 (WO2018115380, WO2019122129) developed by Boehringer Ingelheim has entered the I phase clinical experiment. The SOS1 inhibitor developed by Bayer (WO2018172250, WO2019201848) is still in the preclinical research stage. In recent years, some studies have shown that RAS pathway drugs are prone to produce drug resistance in clinical application, and part of the drug resistance is caused by the negative feedback activation of the upstream RAS pathway after the inhibition of ERK phosphorylation. This negative feedback regulation mechanism is closely related to SOS1. Therefore, the development of SOS1 small molecule inhibitors has broad application prospects.

[0006] AMG-510 is an effective, orally bioavailable, selective KRAS G12C covalent inhibitor developed by Amgen, which is used for treating locally advanced or metastatic non-small cell lung cancer carrying KRAS G12C mutation. Its structure is as follows:

[0249] Experimental operation:

[0250] The pharmacokinetic characteristics of the compounds in rodents after intravenous injection and oral administration are tested according to a standard protocol. In the experiment, the candidate compounds are prepared into clear solutions, and single intravenous injection and oral administration are given to mice. The injection and oral solvents are a mixed solvent prepared from 5% dimethyl sulfoxide, 5% solutol and 90% water. Four male Balb / c mice are used in this project, two mice are given intravenous injection at a dose of 10 mg / kg, and plasma samples are collected at 0.083, 0.25, 0.5, 1, 2, 4, 8 and 24 hours after administration. The other two mice are given oral gavage at a dose of 50 mg / kg, and plasma samples are collected at 0.25, 0.5, 1, 2, 4, 6, 8, 12 and 24 hours after administration. After blood sampling, the blood is placed on ice, and the plasma is centrifuged (centrifugation conditions: 6000g, 3 minutes, 2-8℃) within 1 hour. The plasma samples are stored in a -80℃ refrigerator before analysis. The blood drug concentration is quantitatively analyzed by LC-MS / MS analysis method, and the pharmacokinetic parameters such as peak concentration (C max ), clearance (CL), half-life (T 1 / 2 ), tissue distribution (Vdss), area under the curve (AUC 0-last ), bioavailability (F) and the like are calculated.
