nucleosides with novel scaffolds is of high importance. Here we report the synthesis of novel 2′-hydroxy- and 2′-hydroxymethyl-apionucleosides, 4 and 5, corresponding triphosphates and phosphoramidate prodrugs. Triphosphate 38 of 2′-hydroxymethyl-apionucleoside 5 exhibited potent inhibition of HBV polymerase with an IC50 value of 120 nM. In an HBV cell-based assay, the phosphoramidate prodrug 39 demonstrated
核苷类似物作为抗HBV药物有很好的记录。慢性感染需要长期给药,最终导致耐药性。因此,寻找具有新型支架的核苷非常重要。在这里,我们报告了新的 2'-羟基和 2'-羟基甲基-apionucleosides、4和5、相应的三磷酸酯和氨基磷酸酯前药的合成。2'-羟甲基-apionucleoside 5 的三磷酸38表现出对 HBV 聚合酶的有效抑制作用,IC 50值为 120 nM。在基于 HBV 细胞的测定中,氨基磷酸酯前药39显示出有效的活性,EC 50值为 7.8 nM。
