Abstract
Description
[Technical Field]
[0001] This application claims priority to Chinese Patent Application No. 202211212103.5, filed on September 30, 2022, and Chinese Patent Application No. 202311026791.0, filed on August 15, 2023, which are incorporated herein by reference in their entireties.
[0002] The present disclosure is in the field of pharmaceutical chemistry and, in particular, relates to a group of compounds having inhibitory activity against SAE proteins, methods for their preparation, and the use of such compounds in the preparation of medicaments for treating or preventing related diseases mediated by SAE. [Background technology]
[0003] Small ubiquitin-like modifiers (SUMOs) are a family of ubiquitin-like proteins that function as reversible post-translational modifiers in cells. Mammalian cells express three SUMO family proteins: SUMO1, SUMO2, and SUMO3. SUMO2 shares approximately 95% amino acid sequence identity with SUMO3 and primarily forms oligomeric chains during protein modification. SUMO1 shares approximately 45% sequence identity with SUMO2 and SUMO3 and primarily modifies proteins in its monomeric form. SUMOylation of target proteins involves three enzyme-catalyzed steps that activate, transfer, and ultimately conjugate SUMO proteins to lysine residues on target proteins. The first step is catalyzed by SAEs (SUMO-activating enzymes), a class of activating enzymes known as E1 enzymes, which function as heterodimers consisting of SAE1 and SAE2 / UBA2. SAEs use ATP to adenylate the C-terminal glycine residue of SUMO, forming a thioester intermediate between the C-terminal glycine of SUMO and a cysteine residue in SAE2. The SUMO protein is then transferred from E1 to a SUMO-specific conjugating enzyme, collectively referred to as E2, via thioester bond exchange. Finally, through the action of SUMO-specific E3 protein ligases, the SUMO protein is finally conjugated to a lysine residue on a target protein, forming an oligomeric chain. Protein sumoylation affects catalytic activity, subcellular localization, and interactions with other proteins. Furthermore, recent studies have shown that protein sumoylation plays an important role in various cell signaling pathways, including cell division, DNA repair, chromosome segregation, nuclear transport, gene transcription, and immune regulation. Overexpression of proteins related to the SUMO signaling pathway is associated with poor prognosis in certain cancer patients. Knockdown of SAEs has shown synthetic lethality in certain MYC-overexpressing tumor cells. Furthermore, sumoylation can also regulate innate immune responses. Inhibition of sumoylation enhances the expression of type 1 interferon (IFN). In short, there is an urgent need to research and identify compounds with potent activity targeting SAE.

[0057] Further forms of the compound As used herein, the term "pharmaceutically acceptable" refers to a substance, such as a carrier or diluent, that does not cause a loss of biological activity or properties of a compound and is relatively non-toxic. For example, when administered to an individual, the substance does not cause undesired biological effects or adverse interactions with any of its components.
[0058] The term "pharmaceutically acceptable salt" refers to a form of a compound that does not significantly irritate the receiving organism or eliminate the biological activity and properties of the compound. In certain specific embodiments, the pharmaceutically acceptable salt is obtained by reacting a compound of the general formula with an acid or base, where the acid or base is selected from the group consisting of: Stahl and Wermuth, Handbook of Pharmaceutical Salts: properties, Selection, and Use, 1 st Ed., (Wiley, 2002), but are not limited to these.
[0059] It should be understood that pharmaceutically acceptable salts include solvent addition forms or crystalline forms, particularly solvates or polymorphs. Solvates contain stoichiometric or non-stoichiometric amounts of solvent and are preferentially formed upon crystallization in pharmaceutically acceptable solvents such as water and ethanol. Hydrates are formed when the solvent is water, and alcoholates are formed when the solvent is ethanol. Solvates of compounds of general formula (1) are conveniently prepared or formed according to the methods described herein. For example, hydrates of compounds of general formula (1) are conveniently prepared by recrystallization in a water / organic solvent mixture, where the organic solvent used includes, but is not limited to, tetrahydrofuran, acetone, ethanol, or methanol. Furthermore, the compounds described herein can exist in either unsolvated or solvated forms. In general, solvated forms are considered equivalent to unsolvated forms for the purposes of the compounds and methods provided herein.
[0060] In other specific examples, the compound of general formula (1) is prepared in different forms, including, but not limited to, amorphous, pulverized, and nanoparticle forms. Furthermore, the compound of general formula (1) may be a polymorph, including crystalline forms. Polymorphs contain different lattice arrangements of the same elements of a compound. Polymorphs generally have different X-ray diffraction patterns, infrared spectra, melting points, densities, hardnesses, crystalline forms, optical properties, electrical properties, stability, and solubility. Various factors, such as recrystallization solvents, crystallization rates, and storage temperatures, may result in a single predominant crystalline system.
[0061] In another embodiment, the compounds of general formula (1) may have chiral centers and / or axial asymmetry and therefore may exist in the form of racemates, racemic mixtures, single enantiomers, diastereomeric compounds, single diastereomers, and cis-trans isomers. Each chiral center or axial asymmetry independently produces two optical isomers, and all possible optical isomers, diastereomeric mixtures, and pure or partially pure compounds are included within the scope of the present disclosure. The present disclosure is meant to include all such isomers of these compounds.

[0013] The compounds may be labeled with radioactive isotopes such as CI (C). As another example, deuterium can be used to replace a hydrogen atom to form a deuterated compound. The bond formed between deuterium and carbon is stronger than the bond formed between normal hydrogen and carbon. Compared to non-deuterated drugs, deuterated drugs generally have advantages such as reduced toxicity and side effects, improved drug stability, enhanced efficacy, and prolonged in vivo drug half-life. All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are within the scope of the present disclosure.

[0090] The term "membered ring" includes any cyclic structure. The term "membered" refers to the number of main chain atoms that form the ring. For example, cyclohexyl, pyridinyl, pyranyl, and thiopyranyl are six-membered rings, and cyclopentyl, pyrrolyl, furanyl, and thienyl are five-membered rings.
[0091] The term "moiety" refers to a specific portion or functional group of a molecule. A chemical moiety is generally considered to refer to a chemical substance contained in or attached to a molecule.
[0092] The term "isomer" refers to any tautomer, stereoisomer, atropisomer, isotopic isomer, enantiomer, or diastereomer of a compound of the present disclosure. The compounds of the present disclosure may have one or more asymmetric centers or double bonds and therefore exist in the form of stereoisomers, e.g., double bond isomers (i.e., E / Z geometric isomers), or diastereomers (e.g., enantiomers (i.e., (+) or (-)) or cis / trans isomers). Thus, the compounds of the present disclosure encompass all corresponding stereoisomers, i.e., stereoisomerically pure (e.g., geometrically pure, enantiomerically pure, or diastereomerically pure) forms, as well as mixtures of enantiomers and stereoisomers, e.g., racemates. Enantiomeric and stereoisomeric mixtures of the compounds of the present disclosure can be resolved into their constituent enantiomers or stereoisomers by well-known methods such as chiral gas chromatography and chiral high-performance liquid chromatography, as well as by crystallizing the compounds in the form of chiral salt complexes or in chiral solvents. Enantiomers and stereoisomers can also be obtained from stereomerically or enantiomerically pure intermediates, reagents, and catalysts by well-known asymmetric synthetic methods. The term "isotopomers" refers to distinct molecules that differ only by isotopic composition, but are otherwise identical in structure.
[0093] The term "atropisomer" refers to a conformational stereoisomer that occurs when rotation around a single bond within a molecule is hindered or extremely slowed by steric interactions with other parts of the molecule, and the substituents on both ends of the single bond are asymmetric, i.e., the atropisomer does not require a stereocenter. If the rotational hindrance around the single bond is sufficiently high and the interconversion between conformations is sufficiently slow, separation of individual isomers may be possible, preferably by chiral resolution methods (LaPlante et al., J. Med. Chem. 2011, 54, 20, 7005).
[0094] Unless otherwise indicated, the absolute configuration of a stereocenter is indicated by a solid wedge bond. [ka] and wedge-shaped dashed bond [ka] and the relative configuration of the stereocenters is represented by a straight solid bond [ka] and straight dashed bond [ka] It is represented by the wavy line [ka] is a solid wedge connection [ka] or wedge-shaped dashed bond [ka] or a wavy line [ka] is a straight solid line connection [ka] or straight dashed bond [ka] Represents.
