Definitions

  • the present invention belongs to the field of medicinal chemistry, and more specifically, to a new type of K-Ras G12C inhibitor, its preparation method and the use method of the compound.
  • Ras protein family is an important signal transduction and transmission molecule in cells, which plays an important role in growth and development.
  • the analysis and research of a large number of in vitro tumor cells, animal models and human tumor samples show that the excessive activation of Ras family proteins is an early event in the development of human tumors, and is one of the important causes of the occurrence and development of many cancers. Therefore, targeting and inhibiting the activity of Ras protein are important means for the treatment of related tumors.
  • Ras protein There are two forms of Ras protein. It binds to GDP and is in an inactive resting state; when cells receive signals such as growth factor stimulation, Ras protein binds to GTP and is activated.
  • the activated Ras protein recruits a variety of signal transfer proteins, promotes the phosphorylation of downstream signal molecules such as ERK and S6, thereby activating the Ras signal transduction pathway, regulating cell growth, survival, migration and differentiation.
  • the GTPase activity of Ras protein itself can hydrolyze GTP back to GDP.
  • GAPs GTPase activating proteins
  • K-Ras, H-Ras and N-Ras proteins in the Ras protein family are one of the common gene mutations in many tumors, and are the main factors leading to the excessive activation of Ras protein in tumors. Compared with the wild-type Ras protein, these mutations cause the Ras protein activity to be unregulated, stably bind to GTP, and continue to activate, thereby promoting the growth, migration and differentiation of tumor cells.
  • K-Ras protein mutations are the most common, accounting for 85% of all Ras mutations, while N-Ras (12%) and H-Ras (3%) are relatively rare.
  • K-Ras mutations are extremely common in a variety of cancers: including pancreatic cancer (95%), colorectal cancer (45%) and lung cancer (25%), and relatively rare in breast cancer, ovarian cancer and brain cancer ( ⁇ 2%). K-Ras mutation sites are mainly concentrated in G12, and G12C mutations are the most common. For example, in non-small cell lung cancer (NSCLC), K-Ras G12C accounts for 50% of all K-Ras mutations, followed by G12V and G12D.
  • NSCLC non-small cell lung cancer
  • Genomics studies have shown that the K-Ras mutation in non-small cell lung cancer does not coexist with EGFR, ALK, ROS1, RET, and BRAF mutations, but coexists with mutations such as STK11, KEAP1, and TP53, suggesting that K-Ras mutations may be associated with STK11, KEAP1 Synergistic effects with TP53 mutations are involved in the malignant transformation, proliferation and invasion of cells.
  • the abnormal activation of Ras protein is also involved in non-neoplastic diseases such as diabetes and neurodegenerative diseases. It can be seen that small molecule compounds targeting Ras protein can enable a large number of cancer patients and Ras with specific gene mutations. Non-cancerous patients with excessive activation of the pathway benefit.
  • Ras protein treatment is launched. Therefore, the development of highly active small molecule inhibitors against Ras protein, especially K-Ras G12C protein with high mutation frequency, has important clinical significance.
  • Mirati Company reported in patents WO2017/201161, WO2019/099524 and US2019/270743 K-Ras G12C inhibitors with tetrahydropyridopyrimidine as the core. These compounds have disadvantages such as poor activity or instability. For example, in US2019/270743 The stability of compound A (Example 7) is poor. In addition, some compounds have low activity.
