D-Nucleoside analogs, which are in the natural configuration, as well as the L-nucleoside analogs, are clin. relevant antiviral and anticancer agents. Metabolism of L-nucleoside analog diphosphates to the triphosphates, however, remains unexplored. Studies with recombinant nm23-H1 and -H2 isoforms indicated that L-nucleoside analog diphosphates were not phosphorylated by their nucleoside diphosphate kinase (NDPK) activity. Therefore, roles of creatine kinase, 3-phosphoglycerate kinase, and pyruvate kinase were evaluated using preparations from com. sources and human HepG2 cells. Phosphorylation of L-OddC, L-SddC, L-Fd4C, L-FMAU, and L-ddC were compared with D-deoxynucleoside analogs, Ara C, dFdC, and D-FMAU, and D-dideoxynucleoside analogs, ddC and d4T. Results based on preparations from HepG2 cells showed that L-nucleoside analog diphosphates were selectively phosphorylated by 3-phosphoglycerate kinase, whereas, D-deoxynucleoside analog diphosphates were phosphorylated by NDPK. Interestingly, ddCDP and d4TDP were substrates for creatine kinase, but were not phosphorylated by NDPK. In conclusion, it is proposed that specificity of the phosphorylating enzymes toward the nucleoside analog diphosphates is dependent on the configuration of the analog (L or D) and the presence or absence of 3′-hydroxyl group in the sugar moiety. The enzymic process of phosphorylation of L- and D-nucleoside analog diphosphates is different in cells. This study involved multiple reactions and reactants, such as 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3Safety of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).
1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3) belongs to pyrimidine derivatives. The aromatic compound pyrimidine, and its derivatives, are ubiquitous in nature. They are found in nucleic acids, vitamins, amino acids, antibiotics, alkaloids, and a variety of toxins. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Safety of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione
