[Technical field]

[0002] The present invention relates to the field of pharmaceutical technology, in particular to fused ring compounds, pharmaceutical compositions containing the same and applications. [Background technology]

[0003] The KRAS (Kirsten Rat Sarcoma Viral Oncogene Homolog) gene belongs to the RAS family, which includes two other genes HRAS and NRAS, with a homology between each gene reaching 85%. Essentially, KRAS is a monomeric G protein with GTP enzyme activity located on both sides of the cell membrane, and the protein encoded thereby is a 21KD molecular weight protein consisting of 188-189 amino acids. KRAS acts as an important regulatory component in signal transduction pathways such as tumor cell growth and angiogenesis, and can control and regulate the pathway of cell growth in normal cases, while in abnormal cases, it allows cells to continue growing and prevents cells from self-destructing. When the KRAS gene is mutated, the gene is permanently activated and continuously stimulates cell growth, causing intracellular signal transduction to become confused, cell proliferation to become uncontrollable, and as a result, cancer.

[0004] KRAS is the most common cancer mutated gene in humans, and about 30% of all cancers, including 95% of pancreatic ductal adenocarcinoma (PDAC), 45% of colon and rectal cancer (CRC), and 35% of non-small cell lung cancer (NSCLC), are associated with KRAS mutation activation. Due to protein structure problems, KRAS has been considered an "undruggable" target in the field of oncology drug research and development. However, with more and more research, researchers have found that some specific mutant KRAS proteins form drug-interacting sites, and after binding with small molecule drugs, they can lock KRAS in an inactive KRAS protein-GDP state, suppressing the activation of the KRAS pathway and initiating anti-tumor effects. In recent years, several KRAS G12C drug candidates have entered clinical trials, among which Amgen's AMG 510 and Mirati Therapeutics' MRTX 849 have progressed the fastest. Although the former has been approved for marketing by the FDA, G12C is not the predominant KRAS mutation subtype. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above circumstances, the present invention provides a fused ring compound, a pharmaceutical composition containing the same, and applications thereof. The compound provided by the present invention can be used to treat one or more cancers caused by KRAS mutations selected from cancers caused by KRAS G12C, KRAS G12V, KRAS G12A and G12D mutations, and in particular, as a G12D inhibitor, it has high inhibitory activity and good utilization rate, and can be used to manufacture prophylactic and / or therapeutic drugs for KRAS G12D-mediated diseases, and has good prospects for application.

[0094] Most KRAS missense mutations occur at codon 12, resulting in a change from glycine to another amino acid. The major KRAS missense mutations are KRAS G12D and KRAS G12V mutations, which are found in 90% of pancreatic cancers. KRAS G12D is found as the most common KRAS mutation in colon cancer. Unfortunately, there are no clinical or commercially available drugs for KRAS G12D and KRAS G12V, as the amino acid residues at the mutated sites are difficult to chemically bond.

[0095] The first KRAS G12D inhibitor compound, MRTX1133 (WO2021041671), was reported by Mirati Therapeutics and was able to selectively bind to KRAS G12D mutant proteins and inhibit downstream ERK phosphorylation with high activity, demonstrating sustained dose-dependent suppression of KRAS-dependent signals in animal models of pancreatic and colorectal cancer. However, the plan to start clinical trials for the compound this year has been postponed, and Mirati has decided to change the candidate drug, which was originally expected to be a conventional oral or intravenous formulation, to a long-acting formulation that requires injection of a small amount of MRTX1133. Therefore, MRTX1133 should still have undisclosed drawbacks such as toxicity and side effects. In addition, a compound with KRAS G12D inhibitory activity (WO 2021 / 106231) was disclosed by Taiho Pharmaceutical Co., Ltd., but is still in the early research stage.

[0096] There are several development strategies for KRAS inhibitors, including those that target upstream and downstream targets or those that indirectly target KRAS. However, these strategies may have problems, such as activating bypass pathways or inhibiting normal KRAS activity, and research into these has not progressed very far. Therefore, the investigation and development of novel and effective KRAS G12D mutation inhibitors is of great clinical value. Effect of the Invention
