synthesis of cyclic pronucleotide (cProTide) derivatives of 5-fluoro-2′-deoxyuridine (FdUrd), utilizing a novel phosphoramidating reagent, is described. Stereochemistry at phosphorus was established by NMR studies and modeling. Cytotoxicity data of representative cProTide derivatives of FdUrd are presented. The observed cell-to-cell variations in activity suggests that it is feasible to screen for structural
描述了一种利用新型的磷酰胺化试剂合成5-氟-2'-脱氧尿苷(FdUrd)的环状前核苷酸(cProTide)衍生物的一步法。通过NMR研究和建模建立了磷的立体化学。给出了代表性的FdUrd cProTide衍生物的细胞毒性数据。观察到的细胞间活性变化表明,筛选cProTide部分中有利于癌细胞代谢激活的结构变化是可行的,这可能导致FdUrd的治疗效果提高。所描述的方法适用于具有可用于修饰的5'-和3'-OH基团的所有抗癌和抗病毒核苷类似物,从而形成能够将5'-单磷酸酯传递至细胞的cProTide衍生物。
