phosphoamidate derivatives of nucleoside 2′-acetylene-7-deaza-adenosine (NITD008) were synthesized and evaluated for their in vitro antiviral activities against the enteroviruses EV71 and EV-D68. The phosphoamidate (15f) containing a hexyl ester of l-alanine exhibited the most promising activity against EV71 (IC50 = 0.13 ± 0.08 μM) and was 4-times more potent than NITD008. Meanwhile, the derivative containing
合成了一系列核苷 2'-乙炔-7-脱氮-腺苷 (NITD008) 的氨基磷酸酯衍生物,并评估了它们对肠道病毒 EV71 和 EV-D68的体外抗病毒活性。含有 L-丙氨酸己酯的氨基磷酸酯( 15f )对 EV71 表现出最有希望的活性(IC 50 = 0.13 ± 0.08 μ M),并且比 NITD008 强 4 倍。同时,含有l-丙氨酸的环己酯 ( 15l ) 的衍生物对 EV71 (IC 50 = 0.19 ± 0.27 μ M, SI = 117.00) 和 EV-D68 (IC 50 ) 表现出最有效的活性和高选择性指数 = 0.17 ± 0.16 μ M, SI = 130.76),均高于 NITD008。结果表明,氨基磷酸酯 15l是最有希望进一步开发作为治疗 EV71 和 EV-D68 感染的抗病毒剂的候选药物。
