[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority and benefit to Chinese patent application No. 202410517289.8 filed with the China National Intellectual Property Administration on April 26, 2024, and Chinese patent application No. 202510502592.5 filed with the China National Intellectual Property Administration on April 21, 2025, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] This application belongs to the field of medicinal chemistry and relates to fused bicyclic compounds and their uses, specifically fused bicyclic compounds, their preparation methods, pharmaceutical compositions containing the compounds, and their uses in treating diseases. Background Technology

[0004] Wolframin (WFS1) is a polymeric endoplasmic reticulum transmembrane protein that affects intracellular calcium. 2+ Endoplasmic reticulum stress is regulated by pathways such as homeostasis and unfolded protein response (UPR). Previous studies on WFS1 protein have mainly focused on Wolfram syndrome, diabetes, and Alzheimer's disease, but recent findings show that WFS1 protein is widely expressed in solid tumors. Therefore, WFS1 protein has become a highly promising target for anti-tumor therapy.

[0150] definition

[0151] Unless otherwise stated, the following terms as used in this application shall have the following meanings. 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 a trade name appears herein, it is intended to refer to the corresponding product or its active ingredient.

[0152] The term "substituted" refers to the substitution of one or more hydrogen atoms on a specific atom by a substituent, provided that the valence state of the specific atom is normal and the resulting compound is stable. When the substituent is oxo (i.e., =O), it means that two hydrogen atoms are substituted; oxo substitution does not occur on aromatic groups.

[0153] 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, the ethyl group “optionally” being halogenated means that the ethyl group can be unsubstituted (CH2CH3), monosubstituted (e.g., CH2CH2F), polysubstituted (e.g., CHFCH2F, CH2CHF2, etc.), or fully substituted (CF2CF3). 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.

[0154] The term "substituent" as used herein includes, but is not limited to, the terms "alkyl," "alkoxy," "alkathioyl," "cycloalkoxy," "heteroalkyl," "alkenyl," "alkynyl," "cycloalkenyl," "cycloalkyl," "cycloalkynyl," "heterocycloalkyl," "heterocycloalkenyl," "heterocycloyl," "aryl," "heteroaryl," "alkylene," etc., and their corresponding non-limiting or exemplary groups. Some non-limiting examples of the "substituent" include protium, deuterium, tritium, -OH, -SH, halogen, amino, nitro, nitroso, and cyano. Alkyl, azide group, sulfoxide group, sulfone group, sulfonamide group, carboxyl group, carboxaldehyde group, imine group, alkyl, halo-alkyl, cycloalkyl, halo-cycloalkyl, alkenyl, halo-alkenyl, cycloalkenyl, halo-cycloalkenyl, alkynyl, halo-alkynyl, cycloalkynyl, halo-cycloalkynyl, heteroalkyl, halo-heteroalkyl, alkoxy, alkathioyl, aryl, aryloxy, arylthio, arylalkyl, arylalkoxy, arylalkylthioyl, heteroaryl, heteroaryloxy, heteroarylthioyl, heteroarylalkyl, heteroarylalkoxy, heteroarylalkylthioyl, heterocyclic The group may contain heterocyclic oxy groups, heterocyclic thio groups, heterocyclic alkyl groups, heterocyclic alkoxy groups, heterocyclic alkylthio groups, acyl groups, acyloxy groups, carbamate groups, amide groups, urea groups, epoxy groups, and ester groups, wherein said groups are optionally substituted by one or more substituents selected from the following: oxo, hydroxy, amino, nitro, halogen, cyano, alkyl, alkenyl, alkoxy, haloalkoxy, alkylamino, dialkylamino, haloalkylamino, halodialkylamino, carboxyl, -C(O)O-alkyl, -OC(O)-alkyl, -C(O) NH2, -C(O)NH-alkyl, -C(O)N(alkyl)2, -NHC(O)-alkyl, -C(O)-alkyl, -S(O)-alkyl, -S(O)2-alkyl, -S(O)2NH2, -S(O)2NH-alkyl, -S(O)2N(alkyl)2, cycloalkyl, cycloalkylalkyl, cycloalkyloxy, heterocyclic, heterocyclic alkyl, heterocyclic oxy, heterocyclic alkyl, heterocyclic alkylalkyl, heterocyclic alkyloxy, heterocyclic alkyloxy, heterocyclic aryl, heteroaryl alkyl, heteroaryloxy, aryl, arylalkyl or aryloxy.

[0155] C in this article m-n This means that the part has an integer number of carbon atoms within a given range. For example, "C 1-6 "" means that the group can have 1 carbon atom, 2 carbon atoms, 3 carbon atoms, 4 carbon atoms, 5 carbon atoms or 6 carbon atoms.

[0156] When any variable (e.g., R) appears more than once in the composition or structure of a compound, its definition is independent in each case. Therefore, for example, if a group is substituted by two Rs, each R has an independent option.

[0157] Those skilled in the art will understand that for any group containing one or more substituents, no substitution or substitution pattern is introduced that is spatially impossible and / or cannot be synthesized.

[0158] When the number of a linking group is 0, such as -(CH2)0-, it indicates that the linking group is a covalent bond.

[0159] When one of the variables is selected as a covalent bond, it means that the two groups it connects are directly connected. For example, when L in ALZ represents a covalent bond, it means that the structure is actually AZ.
