5'-nucleotide in vitro. Unfortunately this compound is not sufficiently stable in solution for it to be tested in vivo. The biological properties of this and some related derivatives of (E)-5-(2-bromovinyl)-2'-deoxyuridine and acyclovir have been evaluated in in vitro and in vivo systems designed to show the effects of any intracellular liberation of the nucleotide. Although some of the derivatives are probably
(E)-5-(2-溴乙烯基)-2'-脱氧-5'-O-(3-甲基-2-氧代-5-甲酰基-1,3,2-氧杂磷杂环戊烷-2-基)尿苷合成的且在生理条件下且不需要酶活性的物质,已显示出可在体外产生5'-核苷酸。不幸的是,该化合物在溶液中不够稳定,无法在体内进行测试。(E)-5-(2-溴乙烯基)-2'-脱氧尿苷和无环鸟苷的这种和某些相关衍生物的生物学特性已在体外和体内系统中进行了评估,旨在显示该核苷酸在细胞内释放的作用。 。尽管某些衍生物可能充当了活性核苷的前药,但没有证据表明任何化合物都能释放出有意义浓度的5'-核苷酸。
