phosphoramidate d4T derivatives have been synthesized and evaluated as substrates for HIV-1 RT, and also tested for their in vitro anti-HIV activity. Compounds 2 and 4 are able to inhibit HIV-1 replication to the same extent as d4T and d4TMP in MT-4 cells as well as in CEM/0 cells and CEM/TK−cells. The data suggests that these phosphoramidates are hydrolysed to d4T before exerting their antiviral activity
核苷类似物的抗HIV活性与它们对细胞和病毒激酶以及对HIV-RT的三磷酸酯的底物特异性高度相关。已合成了一系列氨基磷酸酯d4T衍生物,并将其评估为HIV-1 RT的底物,并对其体外抗HIV活性进行了测试。化合物2和4能够抑制HIV-1复制到相同的程度的d4T和d4TMP在MT-4细胞,以及在CEM / 0细胞和CEM / TK -细胞。数据表明,这些氨基磷酸酯在发挥其抗病毒活性之前先被水解成d4T。
