Abstract
Description
Inhibitors of Lactate Dehydrogenase, Compositions Comprising the Inhibitor, and Methods of Use ThereofTechnical Field
[0001] The present disclosure relates to novel compounds that can serve as inhibitors of lactate dehydrogenase, pharmaceutical compositions, comprising at least one of such compounds, and methods of using at least one of such compounds in treating or preventing diseases associated with lactate dehydrogenase activities, such as autoimmune diseases.Background
[0002] Lactate dehydrogenase (LDH) is an important enzyme of the glucose metabolism. It belongs to the class of oxidoreductases and functions to catalyze the reversible conversion of lactate to pyruvate with the reduction of NAD+ to NADH and vice versa. LDH is a tetrameric protein composed of the products of the LDHA (subunit M) and LDHB (subunit H) genes. The tetrameric combination of these gene products generates 5 LDH isoforms with different combinations of subunits depending on the cell type. All LDH isoforms catalyze the last step in the glycolytic pathway converting pyruvate to lactate while regenerating NAD+from NADH. This reaction is important for the production of ATP through glycolysis.
[0003] Lactate dehydrogenase inhibition has been considered as a therapeutic option for cancer treatment. Cancer cells exhibit metabolic characteristics that are different from normal cells. Cancer cells prefer glycolysis over mitochondrial oxidative phosphorylation to regenerate NAD+ and produce essential cellular building blocks, such as amino acids, lipids, and nucleotides that are needed to support rapid cell growth. While aerobic glycolysis is an inefficient way to generate ATP in comparison with oxidative phosphorylation, it generates ATP rapidly. Many non-cancer cells use a combination of oxidative phosphorylation and glycolysis to achieve the metabolic plasticity that is needed to serve their biological functions. The preference of cancer cells for aerobic glycolysis and the enzymes in glycolysis have long been recognized as potential targets for the selective killing of cancer cells. Cancer cells overexpress many glycolytic enzymes, including lactate dehydrogenase (LDH) enzymes A (LDHA) and B (LDHB) .
[0004] Lactate dehydrogenase A (LDHA) inhibition attracts more attention, since it can help regulate the metabolic activity of cells. Genetic knockdown of LDHA has been shown to elicit cell death or delay cell growth in various cell lines, while knockdown of lactate dehydrogenase B (LDHB) has been reported to be less effective in impacting survival of tumor cells. Inhibition of LDHA can lead to a decrease in lactate production and an increase in oxidative phosphorylation, which can help regulate cellular metabolism. Therefore, LDHA inhibition is not only considered as a potential treatment of cancers, but in general a potential treatment of metabolic disorders and other diseases that are associated with altered cellular functions.
[0005] Various pyrazolyl-based compounds substituted with a thiazolyl group that is substituted or unsubstituted for use in inhibiting lactase dehydrogenase activity and for the treatment of one or more symptoms of hyperoxaluria, including primary hyperoxaluria and stone formation in the kidney and urinary tract, were known. See WO2021234543A1 and WO2021234547A1. In addition, thiazole carboxylic acid was considered as a critical substitute, and replacement of the thiazole carboxylic acid with other rings, such as oxazole, pyridine, and other heterocycles, was reported to be markedly detrimental to the activity of compounds. See J. Med. Chem., 60 (22) , pp. 9184-9204 (2017) .
[0006] In addition, substituted pyrazolyl compounds, which inhibit lactase dehydrogenase activity and could be used for treating cancer, have also been known. See J. Med. Chem. 63 (19) , pp. 10984-11011 (2020) ; J. Med. Chem., 60 (22) , pp. 9184-9204 (2017) ; Bioorg. Med. Chem. Lett. 41, Article 127974 (2021) ; WO2016109559A2; and WO2018005807A1.
[0007] However, those LDHA inhibitors do not meet the various needs of the patients. Therefore, there is still a need for better LDHA inhibitors.
