DMTr-2'-F-dU-3'-CE-Phosphoramidite 2'-Deoxy-5'-O-DMTr-2'-fluorouridine 3'-CE phosphoramidite

A phosphoramidite (RO)2PNR2 is a monoamide of a phosphite diester. The key feature of phosphoramidites is their markedly high reactivity towards nucleophiles catalyzed by weak acids e.c., triethylammonium chloride or 1H-tetrazole. In these reactions, the incoming nucleophile replaces the NR2 moiety.

2'-Deoxy-5'-O-DMTr-2'-fluorouridine 3'-CE phosphoramidite is a nucleotide that is used in the synthesis of DNA. It is an organic compound consisting of a molecule with a phosphate group at one end and a ribose sugar at the other. 2'-Deoxy-5'-O-DMTr-2'-fluorouridine 3'-CE phosphoramidite is synthesized on a solid support by reacting nucleophilic reagents with the ribonucleoside. This drug has antineoplastic effects, inhibiting cancer cell growth by interfering with the production of ribonucleic acid (RNA) and protein synthesis. Hydrolysis of this drug releases fluorouracil, which inhibits thymidylate synthase, preventing the conversion of dUMP to dTMP, and thus blocking DNA synthesis.
