Alterations of certain metabolite concentrations and fluxes that occur in response to viral infection are described. Host cell enzymes in the involved metabolic pathways are selected as targets for intervention; i.e., to restore metabolic flux to disadvantage viral replication, or to further derange metabolic flux resulting in “suicide” of viral-infected cells (but not uninfected cells) in order to limit viral propagation. While any of the enzymes in the relevant metabolic pathway can be selected, pivotal enzymes at key control points in these metabolic pathways are preferred as candidate antiviral drug targets. Inhibitors of these enzymes are used to reverse, or redirect, the effects of the viral infection. Drug candidates are tested for antiviral activity using screening assays in vitro and host cells, as well as in animal models. Animal models are then used to test efficacy of candidate compounds in preventing and treating viral infections. The antiviral activity of enzyme inhibitors is demonstrated.
描述了在病毒感染时发生的某些代谢物浓度和通量的改变。选择涉及代谢途径的宿主细胞酶作为干预靶点;即恢复代谢通量以不利于病毒复制,或进一步扰乱代谢通量导致病毒感染细胞的“自杀”(但不包括未感染的细胞),以限制病毒传播。虽然可以选择相关代谢途径中的任何酶,但是在这些代谢途径中关键控制点的关键酶更适合作为候选抗病毒药物靶点。使用这些酶的抑制剂来逆转或重定向病毒感染的影响。使用体外筛选分析和宿主细胞以及动物模型测试药物候选物的抗病毒活性。然后使用动物模型测试候选化合物在预防和治疗病毒感染方面的功效。证明了酶抑制剂的抗病毒活性。
