Description
Technical Field
The invention belongs to the field of medicines, and particularly relates to a 2-anilinopyrimidine derivative with EGFR and ALK inhibition activity, and a preparation method and application thereof.
Background
The tumor molecular targeting therapy is a new tumor therapeutic means which is rapidly developed in recent years, and the principle is a therapeutic method for selectively killing tumor cells based on the inhibition of key factors or proteins closely related to the growth and development of tumors by targeted chemical or biological means. Compared with the traditional anticancer micromolecule medicine, the tumor targeting medicine has the characteristics of strong pertinence, relatively less side effect, good treatment effect and the like, so that the tumor targeting medicine is widely focused, and the tumor targeting therapy is one of the development trends of tumor therapy.
Epidermal Growth Factor Receptor (EGFR) is a receptor type tyrosine protein kinase, plays an important role in vital activities such as proliferation, differentiation, apoptosis and angiogenesis, and is also found to be overactivated or continuously activated in various tumor cells such as lung cancer, breast cancer and prostate cancer. Among them, EGFR mutation is one of the most important drivers in lung cancer patients, and the mutation rate thereof reaches more than 50% especially in Asians. Gefitinib (Gefitinib), a small molecule inhibitor of EGFR marketed in 2003, is used in the treatment of advanced stages of non-small cell lung cancer (NSCLC) and is now also commonly used as a first line medication in EGFR mutated NSCLC patients.
EGFR inhibitor development has been divided into three generations according to the drugs on the market to date. The first generation of EGFR includes the aforementioned Gefitinib and Erlotinib, icontinib, etc., which are directed to NSCLC patients with EGFR in which L858R or del19 mutation is present, and have achieved remarkable clinical efficacy. However, some patients develop drug resistance after 10 to 12 months of drug administration, and the patients can be found to have mainly undergone T790M mutation by gene sequencing and the like, and more than 50% of drug-resistant patients have undergone T790M secondary mutation. In order to solve the problem of first generation inhibitor resistance, second generation EGFR inhibitors have been developed. The second generation inhibitors are irreversible inhibitors, which are inhibitors of wild-type EGFR (EGFR wt ) Also has strong inhibition effect, thus having great toxicity. Second generation EGFR inhibitors that have been marketed include Afatinib and dacominib, but at the clinically Maximum Tolerated Dose (MTD), do not solve the problem of resistance caused by the T790M mutation well. The third generation EGFR inhibitor truly solves the drug resistance problem caused by the T790M mutation, and the American FDA accelerated approval of the Ornitinib (Osimertinib) is obtained in the 11 th month of 2015, so that the drug resistance problem caused by the T790M mutation can be effectively treated in clinic for NSCLC patients with drug resistance, and great success is achieved. However, it is inevitable that some patients who benefit from the treatment for 9 to 14 months have new drug resistance, and researches show that 20 to 40% of patients have drug resistance of Osimertinib due to the occurrence of C797S point mutation. The C797S point mutation refers to the conversion of cysteine to serine at position 797 of EGFR, and position 797 is one of the important sites for covalent binding of osiert inib to EGFR, so that both cannot bind, ultimately resulting in resistance to osiert inib. Currently, no EGFR inhibitors against C797S mutation are marketed, so EGFR inhibitors with high selectivity for C797S are urgently needed to solve the problem of resistance to the third generation inhibitors.
Anaplastic Lymphoma Kinase (ALK) also belongs to receptor type tyrosine kinase, and EML4-ALK chimeric protein generated by mutation of echinoderm microtubule binding protein (EML 4) and ALK fusion gene can promote dimerization of ALK, and related signal channels are continuously activated, so that occurrence and development of cancers are promoted. In smoking patients with NSCLC, EML4-ALK gene fusion mutation occurred in 2.9%; in non-smoking patients, EML4-ALK mutation occurs in 9.4%, so ALK is also one of the main types of mutation in addition to EGFR mutation. With the development of genetic sequencing technology, the simultaneous presence of EGFR and ALK rearrangements is continually being discovered. The literature reports that 2 patients are found to have EML4-ALK fusion mutation after gene sequencing of 14 patients with the resistance to the Orientinib, which also implies that EGFR/ALK dual-target inhibitors can be used for target drug treatment of lung cancer in the future and have a certain potential for solving the problem of resistance to the EGFR.
