series of d4T di‐ or triphosphate derivatives have been synthesized and evaluated as effective substrates for HIV‐1 RT, and also tested for their in vitro anti‐HIV activity. The steady‐state kinetic study of compounds 1–4 in an enzymatic incorporation assay by HIV‐1 RT follows MichaelisMenten profile. In addition, compounds 2–4 are able to inhibit HIV‐1 replication to the same extent as d4T and d4TMP
一系列 d4T 二磷酸或三磷酸衍生物已被合成并评估为 HIV-1 RT 的有效底物,并且还测试了它们的体外抗 HIV 活性。HIV-1 RT 在酶促掺入测定中对化合物 1-4 的稳态动力学研究遵循 MichaelisMenten 曲线。此外,化合物 2-4 能够在 MT-4 细胞以及 CEM/0 细胞和 CEM/TK-细胞中抑制 HIV-1 复制的程度与 d4T 和 d4TMP 相同。数据表明,这些 d4T 多磷酸衍生物在发挥其抗病毒活性之前被水解为 d4T 并重新磷酸化为 d4TTP。
