Description

Technical Field

[0001] The present invention belongs to the field of medicine, and specifically relates to a class of quinoxaline derivatives and their preparation and use. Background Art

[0002] The Warburg effect is one of the important characteristics of tumor cells, which represents the change in the way tumor cells use glucose from oxidative phosphorylation to glycolysis. Normal cells obtain ATP energy through the mitochondrial oxidative phosphorylation pathway, while tumor cells are in uncontrolled division and proliferation, and their demand for energy is particularly strong. Even under normal oxygen concentrations, rapidly proliferating tumor cells will still prefer anaerobic glycolysis to obtain energy. Changes in tumor metabolic pathways are considered to be one of the important driving forces for tumor occurrence and development.

[0003] Phosphoglycerate kinase 1 (PGK1) is a key metabolic enzyme in the glycolysis pathway. It catalyzes the conversion of 1,3-diphosphoglycerate (1,3-BPG) into 3-phosphoglycerate (3-PG) and generates the first ATP in the glycolysis pathway, playing an important role in cellular energy metabolism. Research results in recent years have shown that PGK1 is closely related to the occurrence and development of tumors. A 2016 study showed that the severity of liver cancer patients was positively correlated with the expression of PGK1 protein. After knocking down the pgk1 gene, the glycolysis ability of liver cancer cell lines decreased, the production capacity decreased, the proliferation of cells was inhibited, and the tumor formation ability was weakened. The results suggest that PGK1 may become a molecular target in the treatment of liver cancer. At the same time, PGK1 is associated with multidrug resistance in a variety of malignant tumors. For example, PGK1 is a predictor of low survival in breast cancer patients and a new prognostic biomarker for paclitaxel treatment resistance. In addition, the expression of PGK1 is also significantly upregulated in a variety of other malignant tumors, including pancreatic cancer, colorectal cancer, neuroblastoma, and glioma. Therefore, targeting PGK1 may be an effective strategy for the treatment of malignant tumors.

[0004] Although research on targeted PGK1 inhibitors has great potential in the treatment of malignant tumors, research on PGK1 inhibitors is still in its infancy.

[0005] In summary, there is an urgent need to develop a new class of targeted PGK1 inhibitors in this field. Summary of the invention

[0091] After extensive and in-depth research, the inventors found that replacing the core of the existing quinazoline PGK1 inhibitor with quinoxaline to obtain a class of PGK1 inhibitors with a novel core structure still has PGK1 inhibitory activity, and even some preferred compounds have significantly enhanced PGK1 inhibitory activity, thereby obtaining a class of quinoxaline derivatives with quinoxaline as the core that are novel in structure as PGK1 inhibitors.

A method for preparing the compound of formula I or a pharmaceutically acceptable salt, enantiomer, diastereomer, racemate or deuterated derivative thereof as claimed in claim 1, characterized in that: The preparation method is method one or method two; in, The method 1 comprises the steps of: v) removing the protecting group from compound ie, and then condensing with R4COOH to obtain compound if; vi) optionally removing the protecting group of compound if to obtain a compound of formula I; In each formula, R1' is R1 or R1 protected by a protecting group, and R2' is R2 or R2 protected by a protecting group; A, X, R1, R2, R3 and R4 are as defined in claim 1; The second method comprises the steps of: ii) in an inert solvent, under the catalysis of Pd, compound iia-1 is reacted with R b -C≡CH to carry out coupling reaction, thereby obtaining a compound of formula I; in, In the compound of formula I, A, X, R1, R2, R3, R4, R b and R s1 As defined in claim 1.

8. Use of a compound of formula I as claimed in claim 1 or a pharmaceutically acceptable salt, enantiomer, diastereomer, racemate or deuterated derivative thereof, or a pharmaceutical composition as claimed in claim 6 in the preparation of (i) a PGK1 inhibitor and / or (ii) a medicament for treating or preventing a disease associated with PGK1.

9. The use according to claim 8, characterized in that The PGK1-related disease is selected from: abnormal cell proliferation, abnormal glucose metabolism, hyperkinesia, or a combination thereof.

10. The use according to claim 8, characterized in that The PGK1-related disease is selected from: cancer, hyperkinesia, diabetes, or a combination thereof.

11. The use according to claim 10, characterized in that The cancer is selected from the group consisting of liver cancer, gastric cancer, colorectal cancer, breast cancer, bladder cancer, pancreatic cancer, pancreatic ductal adenocarcinoma, neuroblastoma, prostate cancer, or a combination thereof.

12. An in vitro non-therapeutic method for inhibiting PGK1 activity, comprising the step of contacting PGK1 with the compound of formula I as claimed in claim 1 or a pharmaceutically acceptable salt, enantiomer, diastereomer, racemate or deuterated derivative thereof, thereby inhibiting the activity of PGK1.
