Definitions

• the present invention relates to the field of medicinal chemistry, and more specifically, relates to a novel IDH mutant inhibitor, a preparation method thereof, and a use method of the compound.
• Isocitrate dehydrogenase is an important enzyme involved in the tricarboxylic acid cycle, which catalyzes the conversion of isocitrate into ⁇ -ketoglutarate ( ⁇ -KG). The rate-limiting step of the loop.
• IDH1 is mainly located in the cytoplasm and peroxisomes
• IDH2 and IDH3 are mainly distributed in mitochondria.
• IDH1 and IDH2 are the most frequently occurring metabolic genes. Tumors, myelodysplastic syndromes (myelodysplastic syndromes, MDS) and acute myelogenous leukemia (acute myelocytic leukemia, AML) are present.
• the IDH mutation sites in tumor cells are IDH1Arg132 (R132), IDH2 Arg172 (R172) or IDH2 Arg140 (R140). These mutations lead to the loss of function of the wild-type IDH protein, and instead gain the ability to convert ⁇ -KG to the oncogenic metabolite D-2-hydroxyglutarate (D-2HG).
• the tumorigenic metabolite 2-HG inhibits DNA or histone demethylases, leading to hypermethylation of DNA and histones, which in turn promotes cancer.
• IDH inhibitors can reduce the oncogenic metabolite D-2HG in the body by inhibiting the protein activity of IDH1/R132, IDH2/R172 or IDH2/R140 mutations, induce the demethylation of histone H3K9me3, and achieve the effect of inhibiting tumor development. Therefore, targeting mutant IDH1 and IDH2 (mIDH1 and mIDH2) may be a promising avenue for cancer therapy.
• IDH inhibitors such as Enasidenib and Ivosidenib developed by Agios, both of which are non-covalent inhibitors.
