2-Furylmercury chloride (2-FMC), an organic mercury derivative, has been found to inhibit the replication of all tested human rhinovirus (HRV) serotypes belonging to the antiviral group B and a limited number of HRV serotypes belonging to the antiviral group A. The mechanism of action of 2-FMC was tested against HRV-2 (antiviral group B, minor receptor group), and compared with an antiviral compound for which the viral target was already determined (enviroxime). 2-FMC was found to bind reversibly to virus particles. However, time-dependent plaque reduction assays revealed that 2-FMC did not interfere with early events of HRV-2 replication. Using a quantitative RT-PCR ELISA assay, we were able to prove that 2-FMC inhibits the synthesis of viral RNA. However, the mode of action of 2-FMC is not identical to that of enviroxime, another inhibitor of viral RNA synthesis. Time-of-addition and time-of-withdrawal experiments demonstrated that 2-FMC acted during a broader time interval than enviroxime.
2-氯汞基呋喃(2-FMC)是一种有机汞衍生物,已发现它能抑制所有属于B组抗病毒型的测试人鼻病毒(HRV)血清型以及少数属于A组抗病毒型的HRV血清型的复制。针对HRV-2(B组抗病毒型,次要受体组)测试了2-FMC的作用机制,并与一种病毒靶点已确定的抗病毒化合物(恩韦肟)进行了比较。发现2-FMC与病毒颗粒可逆结合。然而,时间依赖性蚀斑减少试验表明,2-FMC不干扰HRV-2复制的早期事件。使用定量逆转录聚合酶链反应酶联免疫吸附测定法,我们能够证明2-FMC抑制病毒RNA的合成。然而,2-FMC的作用方式与另一种病毒RNA合成抑制剂恩韦肟不同。添加时间和去除时间实验表明,2-FMC的作用时间间隔比恩韦肟更宽。
