Background

Cancer, i.e. malignant tumor, is a serious disease that threatens human health and lives, especially the incidence and mortality of cancer in recent years are on the rapid rise, and the cancer becomes the first killer of human health beyond cardiovascular diseases.

The proliferation, apoptosis, metastasis and the like of tumors are closely related to the abnormality of a certain link in a series of signal transduction pathways inside and outside cells. One important class of molecules in these signaling pathways is protein kinases. Abnormalities in protein kinase activity are not only directly associated with tumors, but are also a major cause of a range of other inflammatory or proliferative responses related human diseases, such as rheumatoid arthritis, cardiovascular and psychiatric diseases, asthma, psoriasis, and the like. At present, four hundred or more human diseases are known to be directly or indirectly associated with protein kinases, which makes protein kinases an important class of drug targets.

Previous studies have shown that Anaplastic Lymphoma Kinase (ALK) is a receptor tyrosine kinase that is a member of the insulin receptor superfamily. ALK is a transmembrane protein with a transmembrane domain at its central site, an extracellular domain at the N-terminus, and an intracellular tyrosine kinase domain at the C-terminus. ALK is normally expressed in isolated regions of the developing nervous system, ALK mRNA is expressed in the small intestine and low in brain, colon, prostate and testis; the lung was not detected; ALK protein is detected in the human retina. The ALK gene can be fused with various protein genes to express and generate an ALK protein; mutations, amplifications, and the like may also be generated. In 1997, the oncogenic ALK gene recombination on the short arm of chromosome 2 on the heterosis large cell lymphoma was first described, and then it was found in other malignancies including diffuse large B cell lymphoma and malignant histoglobulism, and in a variety of solid tumors including inflammatory myofibroblastoma, esophageal squamous cell carcinoma, neuroblastoma and non-small cell lung carcinoma (NSCLC).

The ALK gene is firstly reported in 2007 to encode and produce ALK by forming a fusion gene with the EML4 gene, so that the growth of lung cancer cells is promoted. The EML4-ALK fusion is caused by the short arm insertion of chromosome 2, and several types of mutations have been found to date. The EML4-ALK fusion gene has low positive rate of about 3-7% in common non-small cell lung cancer patients. The EML4-ALK fusion gene is mainly found in non-smoking lung adenocarcinoma and is mutually exclusive to EGFR mutation and KRAS mutation. A study reported in 2010 shows that the EML4-ALK fusion gene positive rate of Chinese lung adenocarcinoma patients is obviously higher than that of European and American patients and is 16.13% (10/62 cases); the positive rate of non-smoking lung adenocarcinoma is 19.23% (10/52 cases); in lung adenocarcinomas lacking EGFR and KRAS mutations, the mutation rate was as high as 42.8% (9/21 cases).

XALKORI (Crizotinib, PF-02341066) from Peezuel corporation of America (Pfizer) was approved by the United states Food and Drug Administration (FDA) to be marketed in 11 months of 2011, and was the first ALK inhibitor non-small cell lung cancer targeted drug to be marketed. The curative effect is remarkable, but similar to other targeted drugs, the drug resistance of patients can be generated after about 10 months of administration. The mechanisms of drug resistance generation are mainly: amplification and overexpression of target genes, change of signal paths and secondary mutation. Subsequently, Ceritinib, Alectonib and Brigatinib which are approved to be marketed successively have higher activity on wild-type and secondary mutant ALK kinase, but simultaneously have new mutations such as solvent front mutation G1202R and the like.

Tropomyosin-related receptor tyrosine kinases (TRKs) are important transmembrane proteins, which are high affinity ligands for neurotrophic factors and play important roles in higher-level functions such as neuronal cell survival, proliferation, differentiation, migration, apoptosis, and learning and memory. TRK, however, begins to clone in the extracellular region as an oncogene fused with the tropomyosin gene. Activation mutations caused by chromosomal rearrangements or mutations in NTRK1(TRKA) are found in both papillary and medullary thyroid carcinomas, non-small cell lung cancer. Because TRKs play an important role in signal pathways of pain sensation, survival and proliferation of tumor cells, TRK inhibitors can be applied to the treatment of pain and cancer. No TRK inhibitors are currently approved for marketing, and various projects are essentially in clinical or preclinical stages of research, such as Entrectinib, larotryptinib, and the like.

ROS1 kinase is a receptor tyrosine kinase, closely related to ALK/LTK and insulin receptor kinase familyAnd (4) correlating. Although the normal physiological function of ROS1 kinase is not fully studied, its abnormal expression and sustained production of different fusion protein forms that are activated are found in many cancers, such as glioblastoma, non-small cell lung carcinoma, cholangiocarcinoma, ovarian carcinoma, gastric adenocarcinoma, colorectal carcinoma, inflammatory myofibroblastoma, angiosarcoma, epithelioid angioendothelioma, etc. The FIG-ROS1 fusion protein was the first ROS1 fusion protein discovered in glioblastoma multiforme in 2003. ROS1 were found to fuse with a variety of proteins in lung cancer, including TMP3, SDC4, SLC34a2, CD74, EZR, and LRIG3, etc., suggesting that ROS1 kinase is an oncogenic factor in lung cancer. More and more ROS1 fusion proteins are then found in different cancers, such as KDELR2, CCDC6, MSN and the like, and nearly twenty. Clinical trials show that the ALK/MET/ROS1 multi-target inhibitor Crizotinib has obvious curative effect on cancer patients with abnormal ROS1 expression. Like other targeted drugs, patients also develop secondary mutations such as ROS1 after a period of time following drug administration^G2032RAnd resistance due to activation of the shunt signal. Taken together, ROS1 kinase is a reliable target for the treatment of many cancers with abnormal ROS1 protein kinase activity. At present, no inhibitor against ROS1 is approved for marketing, and all projects are basically in clinical or preclinical research stage, such as Crizotinib, Lorlatinib, TPX-0005 and the like.

Not only will multi-target inhibitors have broader indications, but inhibition of multiple signaling pathways is expected to reduce resistance due to activation of alternative signals.

The substituted quinolinone compound provided by the invention has very good multi-target inhibition activity, the activity of the quinolinone compound is equivalent to or better than that of a multi-target kinase inhibitor TPX-0005 entering phase I clinic, and the quinolinone compound has very good in vivo metabolism level, and is expected to become a more suitable multi-target inhibitor medicine.
