Title: Compounds used as kinase inhibitors and application thereof

Description:
TECHNICAL FIELD 
     The disclosure relates to a class of compounds used as kinase inhibitors and an application thereof, which belongs to the technical field of drugs. 
     DESCRIPTION OF RELATED ART 
     The epidermal growth factor receptor belongs to the receptor tyrosine kinase (RTK) family, which includes EGFR/ERBB1, HER2/ERBB2/NEU, HER3/ERBB3, and HER4/ERBB4. The epidermal growth factor receptor activates the tyrosine kinase activity thereof through homodimerization or heterodimerization, which in turn phosphorylates the substrate thereof, thereby activating multiple downstream pathways associated therewith in cells, such as the PI3K-AKT-mTOR pathway involved in cell survival and the RAS-RAF-MEK-ERK pathway involved in cell proliferation. Mutation or amplification of the epidermal growth factor receptor may lead to the activation of the epidermal growth factor receptor kinase, thereby leading to the occurrence of various human diseases, such as malignant tumors. For example, among patients with non-small cell lung cancer, more than 10% of patients in the United States have EGFR mutations, while the proportion of patients with the EGFR mutations in Asian patients can reach nearly 50%. Meanwhile, among the patients with non-small cell lung cancer, the incidence of Her2 mutation is about 2-4%. 
     The EGFR mutations mainly include deletion, insertion, and point mutation, among which exon 19 deletion and L858R point mutation of exon 21 account for nearly 90% of the EGFR mutations. For tumor patients with the EGFR mutations, currently marketed EGFR-TKIs include the first-generation Iressa, Tarceva, and Conmana, the second-generation afatinib and dacomitinib, and the third-generation osimertinib. The other 10% of the EGFR mutations mainly involve EGFR exon 18 and 20, and EGFR exon 20 insertion mutation accounts for about 9% of all the EGFR mutations. Among tumor patients with Her2 mutations, the most common Her2 mutation is Her2 exon 20 insertion mutation. For EGFR and Her2 exon 20 insertion mutations, there are currently no drugs on the market. 
     Recently, TAK-788 has been reported to have some activity on clinical EGFR exon 20 insertion mutation. Judging from the reported clinical trial results, the clinical response rate is only about 40%, and the curative effect is not satisfactory. Currently, the compound is still under clinical research. 
     SUMMARY 
     In order to meet the medication requirements of patients with EGFR and Her2 mutations, especially patients with EGFR and Her2 exon 20 insertion mutations, the disclosure has developed a series of compounds with excellent activity on EGFR and Her2 exon 20 insertion mutations, EGFR exon 19 deletion, and L858R point mutation of exon 21, which have great potential to be developed into drugs for treating related diseases.

     II. Biological Experiment Part 
     1. Kinase Activity Assay 
     The kinase activity assay was used to screen the activities of the compounds prepared in the examples on EGFR exon 20 insertion mutant kinase at the ATP Km concentration, and Staurosporine and the compound (TAK788) with the optimal activity disclosed in WO2015195228A1 were used as control substances. The biological activity screening of the compounds was repeatedly determined at 10 concentrations. 
     
       
         
         
             
             
         
       
     
     1. Test Sample 
     Each sample was prepared respectively as a solution at a concentration of 10 mM. 
     2. Experimental Method 
     (1) Basic Buffer Solution and Quench Buffer Solution were Prepared for Experimental Kinase 
     20 mM Hepes (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSO. 
     (2) Compound was Prepared for Experimental Kinase 
     The test compound was dissolved to a specific concentration in 100% dimethyl sulfoxide. DMSO was assisted with Integra Viaflo Assist for (serial) dilution. 
     (3) Reaction Steps 
     Kinase was added to a freshly prepared basic reaction buffer solution, any required cofactor was added to the substrate solution. 
     EGFR exon 20 insertion mutant kinase was added to the substrate solution, gently mixed; compounds in 100% dimethyl sulfoxide were fed into a kinase reaction mixture using acoustic technology (Echo550; nanoliter range), incubated for 20 minutes at room temperature. 
     33P-ATP (specific activity 10 Ci/l) was added to the reaction mixture, reaction started, incubated for 2 hours at room temperature, radioactivity was detected using filter-binding method. 
     Kinase activity data were expressed as a percentage of remaining kinase activity in the test sample compared to a medium (dimethyl sulfoxide) reaction. IC50 values and curve fitting were obtained using Prism (GRAPHPAD software). 
     The obtained inhibitory activity IC50 (nM) values of the test samples on EGFR exon 20 insertion mutant kinase are shown in Table 4.

     As can be seen from Table 4, through the in vitro biological activity screening, with Staurosporine as the control substance, the compounds we used as the kinase inhibitors had good inhibitory ability on EGFR exon 20 insertion mutant kinase, and the inhibitory activities of most of the compounds were much higher than that of Staurosporine. Also, the activities were comparable to that of the compound with the optimal activity disclosed in WO2015195228A1. The activity of the compound of our Example 12 was 2 to 3 times that of the compound with the optimal activity disclosed in WO2015195228A1, which is highly expected to be further developed into a drug for adjusting EGFR exon 20 insertion mutant kinase activity or treating related diseases of EGFR exon 20 insertion mutant kinase.

     It can be seen from Table 5 that the compounds we synthesized had good inhibitory ability on EGFR exon 20 insertion mutation. The activities of most of the compounds were much higher than that of AZD9291. Compared with the activity of TAK-788, most of the compounds of the disclosure had higher activities. For example, the activity of our compound (Example 18) was around 2 times the activity of TAK-788 (see Table 6), which is highly expected to be further developed into a drug for adjusting EGFR exon 20 insertion mutation activity or treating related diseases of EGFR exon 20 insertion mutation.

     3. Cell Proliferation Inhibitory Activity Test Experiments of Related EGFR Mutations: 
     1. Experimental Materials: 
     RPMI, purchased from Nanjing BioChannel Biotechnology Co., Ltd. 
     WST-8, purchased from Jinrui Meixiang. 
     Dimethyl sulfoxide (DMSO), purchased from Aikelab. 
     Ba/F3 (EGFRdel19/L858R/C797S), purchased from KYinno Biotechnology Co., Ltd. 
     PC9 (EGFRdel19) and H-1975 (EGFRL858R/T790M) cells, purchased from BeNa Culture Collection. 
     2. Experimental Steps: 
     Cell culture medium: RPMI containing 10% fetal bovine serum, 5 mM HEPES, and 2 mM glutamine. 
     Cell suspension solutions of Ba/F3 (EGFRdel19/L858R/C797S), PC9 (EGFRdel19), and H-1975 (EGFRL858R/T790M) were respectively diluted to 5000 cells/80 microliters, 1500 cells/80 microliters, and 4000 cells/80 microliters, 80 microliters/well, added to a 96-well culture plate. Incubated overnight in a 5% carbon dioxide incubator at 37° C. 
     The compound was diluted to the required concentration in the culture medium at five times the final concentration. 20 microliters of the compound diluent was transferred to a culture plate containing 80 microliters of the cells incubated overnight, and continued to be incubated for 72 hours. 
     After 72 hours, 10 microliters of 6 mg/ml WST8 solution dissolved in a phosphate buffer solution was added, and incubated for 3 hours in 5% carbon dioxide at 37° C. A light absorption value at 450 nm was read and subtracted by an absorption value at 650 nm. 
     The obtained light absorption value was used to calculate cell viability according to the following equation: 
       Cell viability %=(OD determination value/OD drug-free cell)×100
 
     IC50 of the % cell viability corresponding to the compound concentration was calculated with Prizm8.2 software, the results are shown in Table 7.

     It can be seen from Table 7 that the cytostatic activity of Example 18 on H-1975 (EGFRL858/T790M) and C-9 (EGFRdel19) is not much different from osimertinib activity, and is even better than TAK788. Therefore, our compound also has a certain treatment effect on the treatment of related diseases caused by EGFR mutation.
