RELATED APPLICATIONS
[0001] This application is a U.S. National Phase entry under 35 U.S.C. § 371 of International Application No. PCT/CN2021/111411, filed 9 Aug. 2021, which claims the benefit of Chinese Patent Application No. 202010794066.8, filed 10 Aug. 2020, Chinese Patent Application No. 202011546021.5, filed 24 Dec. 2020, and Chinese Patent Application No. 202110676156.1, filed 18 Jun. 2021, the contents of which are incorporated herein by reference in their entireties.
TECHNICAL FIELD
[0002] The present invention belongs to the field of pharmaceutical synthesis, and particularly relates to an EGFR inhibitor, preparation method therefor and application thereof.
BACKGROUND
[0003] Lung cancer is the leading cause of cancer death worldwide, with non-small cell lung cancer (NSCLC) accounting for 85%. Multi-target therapies against epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK) translocations, ROS1 proto-oncogene receptor tyrosine kinase (ROS1) rearrangements and B-raf proto-oncogenes, serine/threonine kinases (BRAF) have been successfully developed and clinically validated. Inhibitors against EGFR can significantly improve progression-free survival of adenocarcinoma in NSCLC, while acquired resistance mutations of these inhibitors can be targeted by the third generation EGFR inhibitors.
[0004] Although classical EGFR activating mutations (Exons 19 and 21) and drug resistance mutation (T790M) can be inhibited by existing medicaments, but insertion mutation of Exon 20 also results in structural activation of EGFR signaling and is insensitive to all of existing EGFR inhibitors. The mutation of Exon 20 is heterogeneous and includes insertions or repeats of 1-7 amino acids between amino acids at positions 762-774 of the EGFR protein. In NSCLC, the mutation frequency of Exon 20 in EGFR is 4-10% of all mutations in EGFR. These mutations are mutually exclusive with other known oncogene-driven mutations and are enriched in adenocarcinomas of women, non-smokers, Asian populations, and non-small cell lung cancer patients. In addition to NSCLC, the insertion mutation of EGFR Exon 20 is also seen in a rare head and neck cancer, namely sinonasal squamous cell carcinoma (SNSCC). In addition, a structurally-similar insertion mutation of Exon 20 is also found in HER2, another member of the EGFR family.
[0005] Several retrospective analytical studies have shown that currently-available first, second and third-generation EGFR inhibitors have limited the therapeutic effect against the insertion mutation of Exon 20, with the exception of the mutation of A763-Y764insFQEA. An irreversible inhibitor Poziotinib and an EGFR/MET bispecific antibody Amivantamab are in clinical trials. Several small-molecule inhibitors, including TAK-788 and TAS-6417, have shown clinically-significant efficacy in non-small cell lung cancer patients with EGFR Exon 20. However, due to their limited selectivity for EGFR wild type, adverse effects in clinical use are unavoidable and may lead to dose limiting toxicity. Meanwhile, the existing compounds may exist clinically the problem of insufficient exposure. Thus, there is an urgent need for small-molecule inhibitors with higher exposure and/or high selectivity against the insertion mutation of EGFR Exon 20 for these patients.
SUMMARY
[0006] The object of the present invention is to provide an EGFR inhibitor, preparation method therefor and application thereof. A series of compounds of the present invention have a strong inhibition effect on the cytological activity of an insertion, deletion or other mutation of EGFR Exon 20, have a high selectivity for EGFR wild type, and can be widely applied to the preparation of medicaments for treating and/or preventing cancer, tumor or metastatic disease at least partially associated with an insertion, deletion or other mutation of EGFR Exon 20, particularly medicaments for treating hyperproliferative diseases and diseases for inducing cell death disorder, so that a new generation of EGFR inhibitors is expected to be developed.

[0152] The term “substituted” means that one or more hydrogen atoms in the group are each independently substituted by a corresponding number of substituents. It goes without saying that a substituent is only in its possible chemical position and consistent with chemical valence bond theory, and those skilled in the art will be able to determine (by studies or theories) possible or impossible substitution without undue efforts. For example, it may be unstable when amino or hydroxy having free hydrogen is bound to a carbon atom having an unsaturated bond (such as olefin).

Stereoisomers resulting from bond lengths, bond angles, intramolecular double bonds, rings and the like are referred to as configuration stereo-isomers, and the configuration stereo-isomers are classified into two categories. Among them, isomers resulting from the fact that a double bond or a single bond of a ring-forming carbon atom cannot rotate freely are referred to as geometric isomers and also as cis-trans isomers, and the isomers are classified into Z, E configurations. For example, cis-2-butene and trans-2-butene are a pair of geometric isomers, and the compounds of the present invention may be understood to comprise the E and/or Z forms if they contain a double bond, as not specifically indicated. Stereoisomers having different optical rotation properties due to the absence of anti-axisymmetry in the molecule are referred to as optical isomers, and are classified into R and S configurations. In the present invention, the term “stereoisomer” may be understood to include one or more of the above enantiomers, configuration isomers and conformational isomers, unless otherwise specified, preferably S configuration.

1. Cell Culture and Inoculation:
-
- [0305] (1) Cells in the logarithmic growth phase were harvested and counted using a platelet counter. Cell viability was detected by Trypan Blue Dye Exclusion Method to ensure cell viability above 90%.
- [0306] (2) The cell concentration was adjusted to reach a desired final density; 90 μL of cell suspension was added to the 96-well plate.
- [0307] (3) The cells were incubated overnight in the 96-well plate at 37° C., 5% CO2 and at 95% humidity.
[0308] 2. T0 Reference Data:
-
- [0309] (1) 10 μL PBS was added to each well of the TO plate containing the cells.
- [0310] (2) The CTG reagent was thawed and the cell plate was equilibrated to room temperature for 30 min.
- [0311] (3) An equal volume of CTG solution was added to each well.
- [0312] (4) The cells were lysed by shaking on an orbital shaker for 5 min.
- [0313] (5) The cell plate was left at room temperature for 20 min to stabilize the luminescence signal.
- [0314] (6) The fluorescence signal values of TO were read.
3. Dilution and Addition of Compounds - [0315] (1) According to the compound information table, a corresponding volume of DMSO was added to the corresponding compound powder to prepare a 10 mM stock solution.
- [0316] (2) A 1000-fold, 3.16-fold-diluted compound solution was prepared.
- [0317] (3) The 1000× diluted compound solution was diluted 100-fold with PBS to prepare a 10-fold compound solution with a maximum concentration of 10 PM, including 9 concentrations, with 3.16-fold dilution, and 10 μL of the medicament solution was added to each well of the 96-well plate to seed the cells. Triplicate wells were set for each compound concentration, with a final concentration of DMSO being 0.1%.
- [0318] (4) The cells were placed in the 96-well plate filled with the medicament at 37° C., 5% CO2 and at 95% humidity, and cultured for 72 hrs before CTG analysis.
4. Fluorescence Signal Reading - [0319] (1) The CTG reagent was thawed and the cell plate was equilibrated to room temperature for 30 min.
- [0320] (2) An equal volume of CTG solution was added to each well.
- [0321] (3) The cells were lysed by shaking on an orbital shaker for 5 min.
- [0322] (4) The cell plate was left at room temperature for 20 min to stabilize the fluorescence signal.
- [0323] (5) The fluorescence values were read.
5. Data Processing
[0324] Data were analyzed using GraphPad Prism 7.0 software and fitted data were regressed using non-linear S-curves to obtain dose-response curves from which IC50 values (in nM) were calculated. The specific experimental results are shown in Table 1:
