Abstract：
:Forty-three pyrimidine derivatives, mainly containing the 4-aminopyrimidine system, have been prepared and evaluated as inhibitors of deoxycytidine kinase. The most effective inhibitors were 2-alkylthio-4-aminopyrimidines and 1-alky-1-cytosines. The best inhibitors in both groups were those with large alkyl substituents, which indicate that hydrophobic bonding is occurring, possibly in the same area adjacent to the active site.

杂志文章abstract：:Isocitrate dehydrogenases 1 and 2 (IDH1/2) are homodimeric enzymes that catalyze the conversion of isocitrate to α-ketoglutarate (α-KG) in the tricarboxylic acid cycle. However, mutant IDH1/2 (mIDH1/2) reduces α-KG to the oncometabolite 2-hydroxyglutarate (2-HG). High levels of 2-HG competitively inhibit the α-KG-depe...
