迫切需要广谱口服抗病毒药物来早期治疗许多临床关注的 RNA 病毒。我们之前描述了 1-O-十八烷基-2-O-苄基-甘油-3-磷酸-RVn (V2043) 的合成,这是一种口服生物可利用的瑞德西韦核苷脂质前药 (RVn, GS-441524),对具有大流行潜力的病毒具有广谱抗病毒活性。在这里,我们比较了 V2043 与含有 sn-1 烷基醚或 sn-2 甘油修饰的新型 RVn 脂质前药的相对活性。我们发现,当针对 5 个病毒家族的临床重要 RNA 病毒进行体外测试时,与 V2043 相比,3-F-4-MeO-Bn、3-CN-Bn 和 4-CN-Bn sn-2 甘油修饰提高了抗病毒活性。这些结果支持继续开发 V2043 和 sn-2 甘油修饰的 RVn 脂质前药,用于治疗治疗方法有限的多种 RNA 病毒。脂质 RVn 单磷酸酯前药是有效的广谱口服抗病毒药。 3-F-4-MeO、3-CN 或 4-CN 修饰可增加体外抗病毒效力。 3-F-4-MeO、3-CN 或 4-CN 修饰的前药在许多细胞类型中都有活性。这些前药是具有大流行潜力的 RNA 病毒的有效抑制剂。
Broad spectrum oral antivirals are urgently needed for the early treatment of many RNA viruses of clinical concern. We previously described the synthesis of 1-O-octadecyl-2-O-benzyl-glycero-3-phospho-RVn (V2043), an orally bioavailable lipid prodrug of remdesivir nucleoside (RVn, GS-441524) with broad spectrum antiviral activity against viruses with pandemic potential. Here we compared the relative activity of V2043 with new RVn lipid prodrugs containing sn-1 alkyl ether or sn-2 glycerol modifications. We found that 3-F-4-MeO-Bn, 3-CN-Bn, and 4-CN-Bn sn-2 glycerol modifications improved antiviral activity compared to V2043 when tested in vitro against clinically important RNA viruses from 5 virus families. These results support the continued development of V2043 and sn-2 glycerol modified RVn lipid prodrugs for the treatment of a broad range of RNA viruses for which there are limited therapies. Lipid RVn monophosphate prodrugs are potent broad spectrum oral antivirals. 3-F-4-MeO, 3-CN, or 4-CN modifications increase in vitro antiviral potency. 3-F-4-MeO, 3-CN, or 4-CN modified prodrugs are active in many cell types. These prodrugs are potent inhibitors of RNA viruses with pandemic potential.
