[0001] Cross-reference to related applications
[0002] This application claims the benefits and priorities of the following Chinese invention patent applications, the entire contents of which are incorporated herein by reference:
[0003] Patent application No. 202411222341.3, filed with the State Intellectual Property Office on September 2, 2024;
[0004] Patent application No. 202411460752.6 was filed with the State Intellectual Property Office on October 18, 2024. Technical Field
[0005] This disclosure pertains to the field of pharmaceutical technology, specifically relating to macrocyclic compounds or stereoisomers of RAS inhibitors or pharmaceutically acceptable salts thereof, pharmaceutical compositions containing them, and their use as RAS inhibitors in the prevention or treatment of related diseases. Background Technology
[0006] The KRAS gene (Kirsten Rat Sarcoma Viral Oncogene Homolog, a homolog of the Kirsten rat sarcoma virus oncogene) belongs to the RAS gene family (RAS was the first human tumor gene discovered; the KRAS gene family also includes NRAS (Neuroblastoma-RAS) and HRAS (Harvey-RAS)). Located on chromosome 12, it participates in intracellular signal transduction. The KRAS protein encoded by the KRAS gene is a small GTPase, belonging to the RAS superprotein family. The KRAS protein has 188 amino acids and a molecular weight of 21.6 kDa. KRAS is activated by binding to GTP and deactivated by binding to GDP. The KRAS protein is regulated by guanine nucleotide exchange factors (GEFs) and GTPase activators (GAPs) to maintain its activation and inactivation states. Activated KRAS proteins primarily activate downstream pathways such as the PI3K-AKT-mTOR signaling pathway, which controls cell production, and the RAS-RAF-MEK-ERK signaling pathway, which controls cell proliferation. Most small molecule drugs work by binding to functionally important pockets on target proteins, thereby modulating their activity. For example, cholesterol-lowering drugs called statins bind to the active site of HMG-CoA reductase, thereby preventing the enzyme from binding to its substrate. Indeed, many such drug / target interactions are known, which may mislead one into believing that with a reasonable amount of time, effort, and resources, small molecule regulators targeting most (if not all) proteins can be discovered. This is not the case. Currently, it is estimated that only about 10% of all human proteins are suitable targets for small molecules. The remaining 90% are currently considered difficult to treat or manage with the aforementioned small molecule drugs. These targets are often referred to as “undruggable.” A large portion of these undruggable targets, or medically important human proteins, do not yet have a studied library of compounds. Therefore, there is great interest in discovering novel molecules that can modulate the function of such druggable targets. Given the importance of the RAS signaling pathway in cancer treatment, targeted therapy against the RAS signaling pathway has become a research hotspot in the field of cancer treatment in recent years. This disclosure identifies a class of heterocyclic compounds that exhibit good killing effects against tumors with different RAS mutations and RAS protein dependence, and can treat RAS mutation-mediated tumors. Summary of the Invention

The compounds disclosed herein include all trans-isomers, which can be pure, single trans-isomers, trans-isomers enriched in one of them, or nonspecific mixtures of each. Separation of isomers is permitted if the rotational potential around the single bond is sufficiently high and the interconversion between conformations is sufficiently slow.

[0144] The diagrammatic representation of racemic or enantiomerically pure compounds in this article is derived from Maehr, J. Chem. Ed. 1985, 62:114-120. Unless otherwise specified, wedge-shaped real and wedge-shaped imaginary bonds are used. The absolute configuration of a solid center is represented by direct real keys and direct virtual keys. It indicates the relative configuration of a stereocenter (such as the cis-trans configuration of alicyclic compounds).

N,N,N',N'-tetramethylchloromethacin hexafluorophosphate (60 mg, 0.21 mmol) and N-methylimidazole (30 mg, 0.36 mmol) were added to the solution under ice bath conditions, and the mixture was reacted under ice bath conditions for 1 hour. The reaction solution was diluted with 15 mL of dichloromethane and poured into 20 mL of water. The mixture was extracted three times with 20 mL of dichloromethane. The combined organic phases were concentrated and purified by high-performance liquid chromatography (HPLC) using a Welch Xtimate C18 column (150 mm length, 30 mm inner diameter, 5 μm particle size; mobile phase A: water (0.225% NH3), mobile phase B: acetonitrile; gradient: mobile phase B from 5% to 95%, elution for 10 column volumes) to obtain compound 2-2 (90 mg, 0.13 mmol, yield: 64%).

[0363] The instruments and equipment required for this experiment include: Eppendorf pipettes; Eppendorf pipettes; Eppendorf centrifuges; ThermoFisher carbon dioxide incubator; Vi-cell XR fully automated cell counter (Beckman Coulter); and Envision microplate reader (Perkin Elmer).
[0364] The cells required for this experiment include: KRAS G12D The mutant cell line AsPC-1 (ATCC#CRL-1682TM) was cultured in RPMI-1640 medium containing 10% FBS.
[0365] Experimental methods:
[0366] AsPC-1 cells were digested from the culture flasks using 0.25% trypsin and resuspended in the corresponding fresh complete culture medium. After counting, the AsPC-1 cell density was adjusted to 2000 cells / 90 μL / well. 90 μL of the solution was added to each well of a 96-well plate and incubated overnight at 37°C with 5% CO2. A 10 mM stock solution of the compound was diluted 10-fold to 1 mM with DMSO, then further diluted 100-fold to 10 μM with complete culture medium. Using this as the starting concentration, a 3-fold serial dilution was performed with complete culture medium containing 1% DMSO, resulting in nine consecutive concentration gradients. 10 μL of each serially diluted compound was then added to each well to ensure a final DMSO concentration of 0.1% in each well. The positive control group consisted of wells without cell seeding; the negative control group consisted of wells with cells but without the compound treatment. The cell culture plates were incubated at 37°C with 5% CO2 for 5 days. Add an equal volume of CellCounting-Lite 2.0 assay reagent to each well of the cell plate, vortex for 2-5 min to allow for complete cell lysis, and incubate at room temperature for 10 min to stabilize the luminescence signal. Read the luminescence value using an Envision microplate reader. Calculate the inhibition rate using the following formula: Inhibition (%) = (Signal) / (Inhibition (%)) negative control –Signal sample ) / (Signal negative control –Signal positive control)*100, then use IDBS XLfit to perform 4-parameter fitting to calculate IC. 50 Numerical value. Measured IC 50 The values are shown in Table 1.
