综述了多金属氧酸盐 (POM) 的抗 RNA 病毒活性,特别强调了其抗呼吸道病毒活性。急性病毒性呼吸道感染的病原体有很多;并且通过快速的临床手段来识别特定病例的相关药物是相当困难的。在感染急性进展期间,在获得明确诊断之前,医生需要开出某些广谱抗病毒药物。 PM-523 是一种含钛的多钨酸盐,在体外表现出有效的抗流感病毒 (FluV) A 和抗呼吸道合胞病毒 (RSV) 活性。已证实雾化吸入 PM-523 对感染 FluV A 的小鼠有治疗效果。 PM-1001 是一种钒取代的多钨酸盐,在体外对 FluV A、RSV、2 型副流感病毒 (PfluV)、登革热病毒、HIV-1 和 SARS 冠状病毒具有抗病毒活性。因此,POM 在体外和体内实验中已被证明是广谱且无毒的抗 RNA 病毒药物,是急性呼吸道疾病一线治疗的有希望的候选药物。
The anti-RNA virus activity of polyoxometalates (POM) is reviewed, with a special emphasis on the anti-respiratory virus activities. There are many causative agents of acute viral respiratory infections; and it is rather difficult to identify the relevant agent in a given case by rapid clinical means. During acute progress of infection before the definitive diagnosis is obtained physicians need to prescribe certain broad spectrum anti-viral drugs. A titanium containing polyoxotungstate, PM-523 exhibited potent anti-influenza virus (FluV) A and anti-respiratory syncytial virus (RSV) activities in vitro. Therapeutic effect of FluV A infected mice with aerosol inhalation of PM-523 was proven. A vanadium substituted polyoxotungstate, PM-1001 has antiviral activity against FluV A, RSV, parainfluenza virus (PfluV) type 2, Dengue fiver virus, HIV-1 and SARS coronavirus in vitro. Thus, POMs have been proven to be broad spectrum and non-toxic anti-RNA virus agents in both in vitro and in vivo experiments and are promising candidates for first-line therapeutics in acute respiratory diseases.
