A series of hitherto unknown (1,4-disubstituted-1,2,3-triazol)-(E)-2-methyl-but-2-enyl nucleosides phosphonate prodrugs bearing 4-substituted-1,2,3-triazoles were prepared in a straight approach through an olefin acyclic cross metathesis as the key synthetic step. All novel compounds were evaluated for their antiviral activities against HBV, HIV and SARS-CoV-2. Among these molecules, only compound
一系列迄今未知的(1,4-二取代-1,2,3-三唑)- (E) -2-甲基-丁-2-烯基核苷带有4-取代-1,2,3-三唑的膦酸酯前药是直接通过烯烃无环交叉复分解制备的化合物是关键的合成步骤。评价了所有新化合物对HBV,HIV和SARS-CoV-2的抗病毒活性。在这些分子中,只有化合物15j(十六烷氧基丙基(HDP)/(异丙氧基羰基-氧基甲基)酯(POC)前药)在Huh7细胞培养物中显示出抗HBV的活性,在10μM时抑制62%,而没有明显的细胞毒性(IC 50 = 66.4)在HepG2细胞中为μM,在10μM时IC 50 = 43.1μM(在HepG2细胞中)。
