5'-O-(4,4'-Dimethoxytrityl)-2'-deoxyuridine (5'-O-DMT-dU) 是一种竞争性的大肠杆菌 dUTP 核苷酸水解酶 (dUTPase) 抑制剂，Ki 值高于 1000 μM。5'-O-(4,4'-Dimethoxytrityl)-2'-deoxyuridine 通过合成核苷亚磷酰胺嵌段用于机器辅助的 DNA 合成。
5'-O-(4,4'-Dimethoxytrityl)-2'-deoxyuridine (5'-O-DMT-dU) is a competitive inhibitor of E. coli dUTP nucleotidohydrolase (dUTPase), with the Ki higher than 1000 μM. 5'-O-(4,4'-Dimethoxytrityl)-2'-deoxyuridine can be used in machine-assisted DNA synthesis by synthesizing nucleosidic phosphoramidite blocks[1][2].
