Description

Technical Field

[0001] This invention belongs to the field of medicinal chemistry and drug synthesis technology, specifically relating to a class of EGFR allosteric inhibitors, their preparation methods, and their pharmaceutical applications. Background Technology

[0002] Epidermal growth factor receptor (EGFR), a member of the HER family, is a transmembrane glycoprotein essential for cell signaling pathways regulating cell proliferation, differentiation, and apoptosis. EGFR overexpression is present in at least 70% of human cancers and can be observed in various types of solid tumors, such as non-small cell lung cancer (NSCLC), breast cancer, glioma, head and neck squamous cell carcinoma, and prostate cancer. Therefore, EGFR tyrosine kinase inhibitors are considered an effective clinical therapy for patients with EGFR-mutant NSCLC.

[0003] The most common mutation in non-small cell lung cancer (NSCLC) is EGFR (L858R), which activates kinases and promotes abnormal cell growth. First-generation small-molecule tyrosine kinase inhibitors are reversible, competing with ATP for binding sites to selectively inhibit L858R variants; representative drugs include gefitinib and erlotinib. In most cases, after a period of treatment with first-generation drugs, patients develop secondary EGFR mutations such as T790M, leading to resistance. Second-generation irreversible small-molecule tyrosine kinase inhibitors emerged to address this. Second-generation drugs, such as afatinib, can inhibit the T790M variant of EGFR, but they lack specificity and indiscriminately attack WT-EGFR, causing severe toxic side effects. Based on first- and second-generation drugs, third-generation irreversible inhibitors were further investigated, resulting in the widely used irreversible inhibitor osimertinib. Furthermore, osimertinib in combination with chemotherapy has been approved as a first-line treatment for patients with EGFR-mutant advanced NSCLC. Similarly, regarding the issue of drug resistance mutations, clinical studies have found that patients using osimertinib for a period of time develop resistance variants characterized by the C797S mutation, preventing third-generation drugs from exerting their anti-cancer effects. The fourth generation is epidermal growth factor receptor tyrosine kinase inhibitors, a new class of targeted drugs developed to address the resistance problem of third-generation inhibitors. This class of drugs aims to solve the drug resistance problem that arises in EGFR-mutant non-small cell lung cancer (NSCLC) patients after treatment with third-generation EGFR-TKIs, particularly targeting the C797S mutation, a resistance mutation point in third-generation drugs. EAI045 is an allosteric inhibitor that targets specific resistant EGFR mutants without affecting the wild-type receptor. This compound inhibited the L858R / T790M mutant EGFR with low nanomolar potency in biochemical analysis, but due to the different efficiencies of the two subunits of the dimer receptor, it could not effectively block EGFR-driven proliferation in cells as a single drug (WO2019164945 A1) (10.1038 / nature17960) (10.1038 / nature08622). Currently, research on fourth-generation inhibitors is stalled, and no drugs have been successfully approved for clinical use. Summary of the Invention

[0004] Objectives of this invention: The first objective is to provide a class of EGFR allosteric inhibitors that can effectively inhibit the proliferation of tumor cells; the second objective is to provide a method for preparing such EGFR allosteric inhibitors; and the third objective is the pharmaceutical application of these EGFR allosteric inhibitors. The compounds of this invention overcome the ineffectiveness of third-generation EGFR inhibitors against drug-resistant C797S point-mutant EGFR and exhibit high selectivity for wild-type EGFR, thus holding promise for the development of a novel class of EGFR allosteric inhibitors.

[0070] Through in-depth research, the inventors of this application have, for the first time, developed an EGFR allosteric agent having the structure of formula (I). This series of compounds is intended for use as a drug in the prevention and / or treatment of tumors, cancers, or metastatic diseases associated with EGFR protein C797S point mutations or other mutations, as well as drugs for tumors, cancers, or metastatic diseases caused by malignant proliferation and induced cell death disorders. Based on this, the present invention was completed.

[0071] The compound of formula (I) of this invention is a fourth-generation allosteric inhibitor, which is effective against drug resistance mutations such as the C797S mutation that occur after third-generation EGFR-TKI treatment. Compared with the first three generations of inhibitors that compete with ATP for binding sites to inhibit tumor cells, the fourth-generation allosteric inhibitor exerts its efficacy based on a different mechanism of action, which helps to overcome acquired drug resistance generated during treatment and makes it more selective, reduces off-target toxicity, and has good drug activity. At the same time, this type of compound has good blood-brain barrier penetration and can effectively treat brain metastases.

[0072] Detailed Explanation: The following examples are merely illustrative of the implementation process, including but not limited to the conditions therein. The compounds of the present invention can be prepared using suitable substances as raw materials according to the general scheme described below, and are specifically illustrated by the following examples. Of course, various known reasonable variations of the conditions and methods of the preparation steps of the illustrative compounds in the examples can also be used to prepare these compounds.
