Description
Technical Field
The invention belongs to the field of pharmaceutical chemistry, and in particular relates to a nitrogen-containing heterocyclic compound, a compound for inhibiting activity of Ras mutein, a preparation method and application thereof.
Background
Ras is the first oncogene identified in human tumors, and was first discovered in two murine sarcoma viruses. There are three members of the Ras gene family, HRas, KRas, NRas respectively. In humansKRas mutations are most common in tumors, accounting for about 85%. Previous studies have shown that KRas mutations are oncogenic because of missense mutations at codon 12, altering the structure of the KRas protein and allowing it to remain active. Ras plays a major role in signaling pathway in activating kinases that control gene transcription, thereby regulating cell differentiation and proliferation, and is intimately involved in tumor cell survival, proliferation, migration, metastasis, and angiogenesis. It is counted that a high proportion of KRas mutations occur in malignant tumors such as pancreatic cancer, colorectal cancer, ovarian cancer, cholangiocarcinoma and the like. However, targeting drugs for common proto-oncogenes such as EGFR, BCL, etc. have been developed for several generations since the first discovery of KRas oncogenes, but targeting drugs for KRas have not been successfully developed all the time. Targeting drugs against KRas pathway mutant tumors have been mainly focused on farnesyl transferase inhibitors and Raf-MEK pathway inhibitors, but have had little effect. In recent years, inhibitors against KRAS-specific gene mutations have been developed as hot spots, although some inhibitors have gradually moved from preclinical hatching to clinical studies, such as KRAS G12C AMG510, MRTX1257, etc., and shows a certain efficacy in early clinical trials. Global first money KRAS G12C The first clinical data of the inhibitor AMG510 was formally published by the american clinical oncology institute held at month 6 of 2019, in which the drug AMG510 was installed to be shown to prevent tumor growth in most patients with non-small cell lung and colorectal cancer with KRas mutations.
However, the current KRas inhibitors are also limited to only KRas G12C Patients with mutations and a large number of KRAS G12C Other than mutation inhibitor drug development has not been broken through, such as highly-developed KRas G12D 、KRas G12V 、KRas G13D And the like. Thus, highly specific and excellent drug-specific KRAS-directed drugs were found and sought G12C Targeted drugs of specific mutant genes other than those have become a great hotspot in the industry. Through the long-term efforts of the inventor, a class of KRAS mutation inhibitors with novel structure and action mechanism, especially KRAS, is discovered G12D The mutation has better activity and drug-forming property.
