Description

Technical Field

[0001] The present invention belongs to the field of pharmaceutical technology, and in particular relates to nitrogen-containing heteroaryl compounds and preparation methods and applications thereof. Background Art

[0002] The epidermal growth factor receptor 2 (HER2, ErbB2) gene is located on the long arm of chromosome 17 (17q21). It is one of the four members of the ErbB family (EGFR / HER1 / ErbB1, HER2 / ErbB2, HER3 / ErbB31 and HER4 / ErbB4) and has tyrosine kinase activity. No ligand that can directly interact with HER2 has been found. HER2 can form heterodimers with other members of the ErbB family to activate the downstream MEK / ERK / MAPK pathway and PI3K / AKT bypass for signal transduction, ultimately promoting cell growth, proliferation and division.

[0003] Overexpression (upregulation) or overactivity (amplification or mutation) of HER2 has been shown to be associated with many cancers, including breast cancer, colorectal cancer, gastric cancer, non-small cell lung cancer, head and neck cancer, ovarian cancer, cervical cancer, bladder cancer, esophageal cancer, endometrial cancer and glioblastoma. The detection rates of HER2 overexpression in lung cancer, breast cancer, gastric cancer, bile duct cancer, ovarian cancer and endometrial cancer are approximately 2.5%, 15% to 25%, 20%, 20%, 27% and 18% to 80%, respectively.

[0004] The detection rate of HER2 mutation in non-small cell lung cancer is about 2%-4%, among which exon 20 insertion mutation accounts for 71% of HER2 mutations, including common subtypes such as A772_G775dup (55.0%), G776delinsVC (8.3%), G778_P780dup (5.6%) and G776delinsLC (2.1%). Other HER2 mutations include exon 19 mutation L755P (1.9%), exon 21 mutation V842I (0.7%), transmembrane domain mutation V659E (4.1%) and G660D (0.9%), and extracellular region mutation D277Y (1.9%), S310F (7.7%), S310Y (1.9%) and A466V (1.4%). In addition, studies have shown that patients with HER2-abnormal cancer are more likely to develop central nervous system metastasis during the course of the disease. Approximately 47% of patients with HER2-mutated non-small cell lung cancer develop brain metastasis, which is associated with a poor prognosis.

[0005] Currently, clinically approved drugs for the treatment of HER2 abnormalities include monoclonal antibodies (mAbs) (trastuzumab, pertuzumab, etc.), small molecule tyrosine kinase inhibitors (TKIs) (lapatinib, tucatinib, neratinib, pyrotinib, etc.) and antibody-drug conjugates (ADCs) (enmetuzumab, demetuzumab).

[0006] Monoclonal antibodies and antibody-drug conjugates have poor selectivity for wild-type EGFR, and monoclonal antibodies and antibody-drug conjugates are large molecule drugs that are not easy to penetrate the blood-brain barrier. In addition, some patients will develop drug resistance or relapse after using monoclonal antibodies (mAbs) for a period of time. Currently approved TKIs include selective TKI (tucatinib) and non-selective TKIs (lapatinib, naractinib and pyrotinib), which show moderate anti-tumor activity against wild-type HER2, but have poor effects on the most common HER2 exon 20 insertion mutation. In addition, non-selective TKIs have poor selectivity for wild-type EGFR and are prone to adverse reactions such as rash and diarrhea. Therefore, it is of great significance to develop HER2 inhibitors that are selective, can penetrate the blood-brain barrier, and have potential inhibitory effects on HER2 exon 20 insertion mutations. Summary of the invention

[0007] In order to solve the defects of the prior art, the present invention aims to provide a nitrogen-containing heteroaryl compound and a preparation method and application thereof. The nitrogen-containing heteroaryl compound has good activity in inhibiting HER2 exon 20 insertion mutation and has high selectivity for wild-type EGFR.
