Abstract
Description
Technical Field
[0001] This invention belongs to the field of medicinal chemistry technology, specifically relating to a pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivative and its applications. Background Technology
[0002] Leukemia is a disease in which, under certain external pathogenic factors, some hematopoietic cells gradually lose their terminal differentiation ability, thus arresting at a certain differentiation stage and ceasing to differentiate normally. This ultimately leads to the continuous proliferation of incompletely differentiated hematopoietic cells at that stage, causing an influx of cells from the bone marrow into the peripheral blood. Leukemia is a serious malignant tumor of the hematopoietic system that severely endangers human health. Acute myeloid leukemia (AML) is the most common and most dangerous type, with the lowest 5-year survival rate compared to other types of leukemia, at only 28.3%. AML is an aggressive malignant disease of hematopoietic cells with a very complex pathogenesis, typically progressing from the initial stage to the terminal stage within just a few months. To date, the treatment of AML remains a major challenge for the medical community.
[0003] Currently, the main treatments for AML include chemotherapy, targeted therapy, differentiation therapy, immunotherapy, and hematopoietic stem cell transplantation. Furthermore, studies on the genetic and molecular characteristics of AML indicate that the disease is often associated with dysregulation of epigenetic mechanisms. In the context of hematologic malignancies, histone demethylase 1 (LSD1) has been found to be overexpressed in approximately 60% of acute myeloid leukemia (AML) cases. Studies have shown that LSD1 promotes leukemia development and proliferation by imposing myeloid maturation arrest and promoting myeloid progenitor cell proliferation. Given the important role of LSD1 in regulating oncogene expression and in hematopoietic systemogenesis and erythrocyte differentiation, LSD1 may become an important target for the treatment of AML.
[0004] Pyrimidines and their derivatives possess a wide range of biological and pharmacological activities, including antitumor, anti-anxiety, antioxidant, antiviral, antifungal, anticonvulsant, antidepressant, and antibacterial effects. As a heterocyclic aromatic system, pyrimidines have attracted considerable attention due to their broad biological and pharmacological activities. To date, several drugs containing pyrimidine structures have been marketed. Triazoles possess various biological activities, including antibacterial, antiviral, and cell growth-inhibiting effects. They are stable in vivo, resistant to metabolic and chemical degradation, heat-resistant, and exhibit strong resistance to hydrolysis, oxidation, and reduction. In drug design, triazoles can also serve as connectors, assembling two or more active groups into a single molecule. This not only preserves the original group's activity but may also produce synergistic effects, increasing effective activity and reducing toxic side effects.
[0005] Patent application No. 202010401690.7 discloses an aromatic ring / heterocyclic triazole-methylene-TCP derivative, which connects a portion of the aromatic ring or heterocyclic ring to triazole to prepare a novel TCP derivative. This derivative exhibits good inhibitory activity against LSD1 and also shows some inhibitory activity against gastric cancer cell lines (MGC-803, SGC-7901), breast cancer cell line (MCF-7), and prostate cancer cell line (PC-3). However, the prior art has not confirmed whether this compound has inhibitory activity against acute myeloid leukemia cells, and no compound structure suitable for development as a lead drug for acute myeloid leukemia has been reported in the prior art.
[0006] Therefore, how to structurally improve and scientifically design the aforementioned compounds to develop novel compounds with good inhibitory activity against acute myeloid leukemia (AML) cells has become a pressing technical problem to be solved in this invention. Furthermore, the development of novel compounds that inhibit AML cells has significant research value and potential application value for the treatment of AML and the development of lead drugs. Summary of the Invention
[0007] To overcome the shortcomings of existing technologies, the primary objective of this invention is to provide a pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivative. This invention, by modifying the structure of the aromatic ring, aromatic heterocyclic ring, and benzene ring, yields a novel class of pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivatives, which exhibit good inhibitory activity against LSD1. In particular, verification revealed that this class of compounds possesses strong inhibitory activity against acute myeloid leukemia MV-4-11 cells, and can be developed as LSD1 inhibitors or lead compounds for anti-acute myeloid leukemia drugs.
[0008] A second object of the present invention is to provide the application of the above-mentioned pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivative.
[0009] To achieve the aforementioned first objective, the technical solution adopted by the present invention is as follows:

[0016]
[0017]
[0018]
[0019]
[0020] Based on the consideration of improving the inhibitory activity of the compound against LSD1 and enhancing the antiproliferative effect on acute myeloid leukemia cells, the pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivative is selected from compounds with the following structures or pharmaceutically acceptable salts thereof:
[0021]
[0022] Preferably, the pharmaceutically acceptable salt is one of hydrochloride or trifluoroacetate.
[0023] To achieve the second objective mentioned above, the technical solution adopted by the present invention is as follows:
[0024] The use of a pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivative as described above in the preparation of an LSD1-targeting inhibitor; or in the preparation of a medicament for treating acute myeloid leukemia.
[0025] Preferably, the drug is a drug that inhibits the proliferation of acute myeloid leukemia cells.
[0026] More preferably, the acute myeloid leukemia cells are MV4-11 cells.
[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0028] The pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivative provided by this invention contains characteristic groups such as pyrimidine, triazole, cyclopropylamine, and fluorosubstituted phenyl groups. In the compound structure design, the phenyl group at the 1-position of the triazole is replaced with pyrimidine, and the fluorine substitution position of the phenyl ring in phenylcyclopropylamine is changed or the fluorine atom is replaced with other groups. Through the comprehensive structural design of the above characteristic groups, a novel compound type is obtained. Experiments have confirmed that the pyrimidine-triazole-fluorosubstituted phenylcyclopropylamine derivative provided by this invention exhibits nanomolar-level inhibitory activity against LSD1 at the enzymatic level, demonstrating significant biological inhibitory activity against LSD1. It can be used to prepare inhibitory drugs targeting LSD1, enriching the types of LSD1 inhibitors containing TCP structures and laying the foundation for the development of novel LSD1 targeted inhibitors. In particular, further research on the anticancer activity of the pyrimidine-triazole-fluoro-substituted phenylcyclopropylamine derivative of this invention in acute myeloid leukemia revealed that this type of compound exhibits strong antiproliferative activity against acute myeloid leukemia cells, thus demonstrating good therapeutic efficacy for acute myeloid leukemia and showing promising drug development potential. It can be developed as a lead drug for treating acute myeloid leukemia. In summary, this invention, through compound structure design and experimental verification, can provide more skeletal structure options for the treatment of acute myeloid leukemia and also offer new directions for the development of LSD1-targeted inhibitors, demonstrating promising application prospects.
