Macrocyclic EGFR degrading agents and their applications
[0001] Cross-references to related applications
[0002] This application claims priority and benefits from the following patent applications, the entire contents of which are incorporated herein by reference:
[0003] Chinese Invention Patent Application No. 202410688893.7, filed with the State Intellectual Property Office of the People's Republic of China on May 30, 2024;
[0004] Chinese Invention Patent Application No. 202510057521.9, filed with the State Intellectual Property Office of the People's Republic of China on January 14, 2025; and
[0005] Chinese Invention Patent Application No. 202510567928.6 was filed with the State Intellectual Property Office of the People's Republic of China on April 30, 2025. Technical Field
[0006] This disclosure relates to macrocyclic compounds or their stereoisomers or pharmaceutically acceptable salts as EGFR degrading agents, methods for their preparation, pharmaceutical compositions containing the compound or its stereoisomers or pharmaceutically acceptable salts, and the use of said compound or its stereoisomers or pharmaceutically acceptable salts in the prevention or treatment of EGFR-mediated or EGFR-related diseases. Background Technology
[0007] Epidermal growth factor receptor (EGFR) is a transmembrane protein belonging to the tyrosine kinase family. EGFR plays a crucial role in physiological processes such as cell growth, proliferation, and differentiation. However, EGFR mutations or overexpression can lead to persistent activation of the EGFR signaling pathway, resulting in abnormal cell proliferation. Studies have shown that 30% of lung cancer patients are caused by EGFR mutations. EGFR-targeted therapy has made rapid progress in the past decade, but with the advancement of treatment, drug resistance has gradually emerged, thus necessitating the development of new treatment methods.
[0008] PROTAC (Proteolysis Targeting Chimera) is a heterobifunctional small molecule composed of three parts: a protein-binding ligand, a ligand that binds to the ubiquitin ligase E3, and a linker connecting the two. PROTAC brings the target protein to be degraded closer to the intracellular ubiquitin ligase E3, forming a target protein-PROTAC-E3 ternary complex. This makes the target protein more easily ubiquitinated by the E3 ubiquitin ligase. The ubiquitinated protein triggers the intracellular ubiquitination-proteasome system, specifically degrading the target protein, reducing its level, and thus inhibiting the protein-mediated signaling pathway. Compared to small molecule inhibitors, PROTAC has better selectivity, overcomes small molecule resistance, and can degrade some difficult-to-treat targets. Furthermore, unlike small molecule inhibitors which merely occupy the target site, PROTAC technology can degrade the target protein, providing more effective inhibition of EGFR-mediated signaling pathways. This has the potential to solve the problem of EGFR small molecule resistance in the current market and become an effective method for treating EGFR-mediated diseases. Summary of the Invention

[0158] Terminology Definitions and Explanations
[0159] Unless otherwise stated, the terms used in this disclosure have the following meanings: the definitions of groups and terms recorded in this disclosure, including definitions as examples, exemplary definitions, preferred definitions, definitions recorded in tables, definitions of specific compounds in the examples, etc., can be arbitrarily combined and combined with each other. A particular term should not be considered uncertain or unclear unless specifically defined, but should be understood in accordance with its ordinary meaning in the art. When trade names appear herein, they are intended to refer to the corresponding product or its active ingredient.
[0160] In this article Indicates the connection site. For this article... of when When not attached to a fixed ring or atom, it indicates that it can be attached to any group within the brackets that contains a substituted hydrogen atom (including hydrogen atoms directly attached to the ring atom, hydrogen atoms on non-hydrogen substituents of the ring atom, and hydrogen atoms in further substituents of the substituent), after the loss of that hydrogen atom. For example... middle The connection locations include, but are not limited to, R 1 and its substituents, ring A, ring B, R 2 and its substituents, R 3 and its substituents, etc. middle The connection locations include R 1 and R 1 Substituent R 1a wait.
[0161] The term "capable of binding" refers to the ability to bind to a target in a measurable manner (e.g., the ligand of an E3 ubiquitin ligase can form a covalent bond with the cysteine residue of the E3 ubiquitin ligase, etc.).
[0162] The term "ubiquitin ligase" refers to a family of proteins that facilitate the transfer of ubiquitin to specific substrate proteins for targeted degradation. E3 ubiquitin ligases, alone or in combination with E2 ubiquitin ligases, are responsible for transferring ubiquitin to target proteins. Typically, ubiquitin ligases participate in polyubiquitination, where a second ubiquitin is linked to a first ubiquitin; a third ubiquitin to a second ubiquitin, and so on. Polyubiquitination labels the protein for degradation by the proteasome. However, there are also ubiquitination events limited to monoubiquitination, where the ubiquitin ligase adds only a single ubiquitin to the substrate molecule. Monoubiquitinated proteins do not target the proteasome for degradation but can instead alter their cellular location or function, for example, by binding to other proteins with domains capable of binding ubiquitin. Further complicating matters, E3 ubiquitin ligases can target different lysine residues on ubiquitin to create chains.
[0163] Unless otherwise specified, use wedge keys and virtual wedge keys. The absolute configuration of a solid center is represented by black solid bonds and imaginary bonds. It indicates the relative configuration of a stereocenter (such as the cis-trans configuration of alicyclic compounds).
[0164] The term "tautomer" refers to a functional group isomer resulting from the rapid movement of an atom between two positions within a molecule. The compounds of this disclosure can exhibit tautomerism. Tautomers can exist in two or more interconvertible forms. Tautomers generally exist in equilibrium, and attempts to isolate a single tautomer typically yield a mixture whose physicochemical properties are consistent with those of the mixture of compounds. The equilibrium position depends on the intramolecular chemical characteristics. For example, in many aliphatic aldehydes and ketones such as acetaldehyde, the ketone form is dominant; while in phenols, the enol form is dominant. This disclosure encompasses all tautomeric forms of the compounds.
[0165] The term "stereoisomer" refers to isomers that are produced by different spatial arrangements of atoms in a molecule, including cis-trans isomers, enantiomers and diastereomers.
[0166] The compounds disclosed herein may have asymmetric atoms such as carbon, sulfur, nitrogen, and phosphorus atoms, or asymmetric double bonds. Therefore, the compounds disclosed herein may exist in specific geometric or stereoisomeric forms. Specific geometric or stereoisomeric forms may be cis and trans isomers, E- and Z-type geometric isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers, (D)- isomers, (L)- isomers, and racemic mixtures thereof or other mixtures, such as mixtures enriched with enantiomers or diastereomers. All such isomers and mixtures thereof are within the scope of the definition of the compounds disclosed herein. Alkyl groups and other substituents may contain additional asymmetric carbon atoms, asymmetric sulfur atoms, asymmetric nitrogen atoms, or asymmetric phosphorus atoms. All such isomers involved in all substituents and mixtures thereof are also included within the scope of the definition of the compounds disclosed herein. The compounds containing asymmetric atoms disclosed herein can be isolated in optically active pure form or in racemic form. The optically active pure form can be separated from racemic mixtures or synthesized using chiral starting materials or chiral reagents.
[0167] The term "substituted" refers to the substitution of one or more hydrogen atoms on a particular atom by a substituent, which can include deuterium and hydrogen variants, provided that the valence state of the particular atom is normal and the substituted compound is stable.

[0168] The terms “optional” or “optionally” mean that the event or condition subsequently described may or may not occur, including both the occurrence and non-occurrence of said event or condition. For example, “optionally” substituted with a halogen means that the ethyl group can be unsubstituted (CH2CH3), monosubstituted (CH2CH2F, CH2CH2Cl, etc.), polysubstituted (CHFCH2F, CH2CHF2, CHFCH2Cl, CH2CHCl2, etc.), or fully substituted (CF2CF3, CF2CCl3, CCl2CCl3, etc.). Those skilled in the art will understand that for any group containing one or more substituents, no substitution or substitution pattern that is spatially impossible and / or cannot be synthesized is introduced.

[0170] The term "substituted" refers to the fact that a specific atom or group can be replaced with a specified other atom or group. For example, the CH2 in -CH2CH2CH2- can be replaced by O, S, or NH to obtain -CH2OCH2-, -OCH2CH2-, -CH2SCH2-, -SCH2CH2-, -CH2NHCH2-, or -NHCH2CH2-, etc.
[0171] When any variable (e.g., R) a R b When a group appears more than once in the composition or structure of a compound, its definition is independent in each case. For example, if a group is surrounded by two R... b Replaced, then each R b Each has its own independent options; for group N(C1-C6 alkyl)2, when C1-C6 alkyl is R b When substituted, the two C1-C6 alkyl groups have independent R groups. b Options.
[0172] When the number of a linking group is 0, such as -(CH2)0-, it indicates that the linking group is a bond.
[0173] When one of the variables is selected as a bond or does not exist, it means that the two groups it is connected to are directly connected. For example, when L in ALZ represents a bond, it means that the structure is actually AZ.
[0174] Unless otherwise specified, the linking direction of the linking groups mentioned in this article is arbitrary.
[0175] When a substituent is cross-bonded to two atoms on a ring, it can bond to any atom on that ring. For example, structural units. R represents 1 Substitution can occur at any of the 1, 2, 3 or 4 positions on the benzene ring.
[0176] C in this article m -C n It refers to having an integer number of carbon atoms, either mn or in the range m to n. For example, "C1-C 10 "" means that the group can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 carbon atoms. Similarly, "m-membered" to "n-membered" indicates that the number of ring atoms is m to n.
