Description

[Technical field]

[0001] The present invention relates to the field of drug synthesis, in particular to 2,3-dihydro-1H-pyrrolo[3,2-b]pyridine derivatives, their preparation methods and uses. [Background technology]

[0002] Lung cancer is the leading cause of cancer deaths worldwide, with non-small cell lung cancer (NSCLC) accounting for 85% of all lung cancers. Multi-targeted drugs targeting epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK) translocations, proto-oncogene receptor tyrosine kinase (ROS1) rearrangements, and B-raf proto-oncogene, serine / threonine kinase (BRAF) have been developed and clinically validated. EGFR inhibitors have significantly improved progression-free survival in adenocarcinoma NSCLC, and after the acquisition of drug resistance mutations (first and second generation), third generation EGFR inhibitors targeting these mutations have been developed.

[0003] Despite successful inhibition of classical EGFR activating mutations (exons 19 and 21) and drug resistance mutations (T790M), in-frame insertions in exon 20 also caused constitutive activation of EGFR signaling and were associated with de novo resistance to existing EGFR inhibitors. Exon 20 mutations are heterogeneous and include in-frame insertions or duplications of amino acids 1–7 between amino acids 762–774 of the EGFR protein. In NSCLC, EGFR exon 20 mutation frequency accounts for 4–10% of all EGFR mutations. These mutations are mutually exclusive with other known oncogenic driver mutations and are more prevalent in women, non-smokers, Asians, and adenocarcinomas in patients with non-small cell lung cancer. In addition to NSCLC, EGFR exon 20 insertion mutations have also been found in a rare form of head and neck cancer, nasal squamous cell carcinoma (SNSCC). Structurally similar exon 20 insertion mutations have also been found in HER2, another member of the receptor tyrosine kinase (RTK) EGFR family.

[0004] Multiple retrospective analyses have shown that currently available first-, second-, and third-generation EGFR inhibitors have limited efficacy against exon 20 insertion mutations, except for the A763-Y764insFQEA mutation. The irreversible inhibitor poziotinib and the EGFR / MET bispecific antibody amivantamab are in clinical trials. Although several small molecule inhibitors, including TAK-788 and TAS-6417, have shown clinically meaningful efficacy in patients with EGFR exon 20 non-small cell lung cancer, these side effects are unavoidable due to their limited selectivity against EGFR WT (wild type), which may lead to dose-limiting toxicity. Therefore, there is an urgent need for highly selective small molecule inhibitors targeting EGFR exon 20 insertion mutations for these patients. Summary of the Invention

[0005] The object of the present invention is to provide 2,3-dihydro-1H-pyrrolo[3,2-b]pyridine derivatives, their preparation method and use. The series of compounds of the present invention have a strong inhibitory effect on the cell biological activity of EGFR exon 20 insertion, deletion or other mutations, and have high selectivity against EGFR wild type, so that they can be widely used for the preparation of medicines for treating and / or preventing cancer, tumor or metastatic diseases associated with at least some of EGFR exon 20 insertion, deletion or other mutations, especially hyperproliferative diseases and cell death / damage-induced diseases, and thus the development of a new generation of EGFR inhibitors is expected.

Examples include, but are not limited to, a difluoromethoxy group, a dichloromethoxy group, a dibromomethoxy group, a trifluoromethoxy group, a trichloromethoxy group, a tribromomethoxy group, and the like.

[0064] "Deuterium substitution C 1-10 The term "alkyl group" refers to an alkoxy group having 1 to 10 carbon atoms in which hydrogen in the alkyl group is optionally substituted with a deuterium atom. Examples include, but are not limited to, a monodeuteromethyl group, a diduteromethyl group, a trideuteromethyl group, and the like.

[0065] "Halogen" refers to fluorine, chlorine, bromine or iodine.

[0066] "Optional" or "optionally" means that the described event or circumstance may, but does not necessarily, occur, and the statement includes cases where the event or circumstance occurs or does not occur, i.e., the two situations of substituted or unsubstituted. For example, "a heterocyclic group optionally substituted with an alkyl group" means that the alkyl group may or may not be present, and the statement includes cases where the heterocyclic group is substituted with an alkyl group and cases where it is unsubstituted.

[0067] "Substitution" refers to the substitution of one or more "hydrogen atoms" in a group with a corresponding number of substituents, independently of each other. Of course, the substituents are in accordance with the valence bond theory in chemistry, and those in the art can easily confirm (experimentally or theoretically) whether or not the substitution is possible, provided that they are in a chemically possible position. For example, an amino group or a hydroxy group having a free hydrogen may be unstable when bonded to a carbon atom having an unsaturated bond (e.g., an olefin).

[0068] The English name for "stereoisomer" is stereoisomer, which refers to an isomer resulting from differences in the arrangement of atoms in a molecule in space. They are divided into cis-trans isomers and enantiomers, and also into enantiomers and non-enantiomers. Stereoisomers resulting from the rotation of a single bond are called conformational stereoisomers, sometimes called rotamers. Stereoisomers resulting from bond length, bond angle, double bonds in a molecule, rings, etc. are called configurational stereoisomers, which are divided into two types. Isomers resulting from the inability to freely rotate the single bonds of double bonds or ring carbon atoms are called geometric isomers, also called cis-trans isomers, and are divided into Z and E configurations. For example, cis-2-butylene and trans-2-butylene are a pair of geometric isomers, and stereoisomers with different optical rotations due to the lack of antiaxial symmetry in the molecule are called optical isomers, and are divided into R and S configurations. In the present invention, unless otherwise specified, the term "stereoisomer" can be understood to include one or more of the above-mentioned enantiomers, configurational isomers, and conformational isomers.

[0069] In the present invention, "pharmaceutically acceptable salts" refers to pharmaceutically acceptable acid addition salts, including inorganic acid salts and organic acid salts, which can be prepared by methods known in the art.

[0070] By "pharmaceutical composition" is meant a mixture of one or more compounds described herein, or physiologically / pharmaceutical salts or prodrugs thereof, with other chemical components, and other components, such as physiologically / pharmaceutical carriers and excipients. The purpose of a pharmaceutical composition is to exert a biological activity by facilitating administration to an organism and contributing to the absorption of the active ingredient.
