黄病毒是人类感染性疾病的主要原因。据估计,登革热病毒每年导致5000万例发热性疾病,其中包括越来越多的出血热病例。西尼罗河病毒最近从地中海盆地传播到西半球,现在每年导致数千例零星脑炎病例。尽管存在获得许可的疫苗,黄热病、日本脑炎和壁虱传播的脑炎每年也在其广阔的流行地区夺走数千名受害者的生命。抗病毒治疗可能会降低黄病毒感染的发病率和死亡率,但目前还没有有效的药物可用。本文介绍了《抗病毒研究》中有关黄病毒抗病毒药物设计的分子靶点和登革病毒病小鼠模型的论文集,旨在鼓励药物开发努力。在回顾了黄病毒的复制周期后,我们讨论了囊膜糖蛋白、NS3蛋白酶、NS3解旋酶、NS5甲基转移酶和NS5 RNA依赖的RNA聚合酶作为潜在的药物靶点,特别是病毒蛋白水解酶。其他病毒蛋白是该杂志个别文章的主题。总之,这些论文强调了针对黄病毒疾病的药物发现工作的现状,并提出了进一步研究的有前景的领域。
Flaviviruses are a major cause of infectious disease in humans. Dengue virus causes an estimated 50 million cases of febrile illness each year, including an increasing number of cases of hemorrhagic fever. West Nile virus, which recently spread from the Mediterranean basin to the Western Hemisphere, now causes thousands of sporadic cases of encephalitis annually. Despite the existence of licensed vaccines, yellow fever, Japanese encephalitis and tick-borne encephalitis also claim many thousands of victims each year across their vast endemic areas. Antiviral therapy could potentially reduce morbidity and mortality from flavivirus infections, but no effective drugs are currently available. This article introduces a collection of papers in Antiviral Research on molecular targets for flavivirus antiviral drug design and murine models of dengue virus disease that aims to encourage drug development efforts. After reviewing the flavivirus replication cycle, we discuss the envelope glycoprotein, NS3 protease, NS3 helicase, NS5 methyltransferase and NS5 RNA-dependent RNA polymerase as potential drug targets, with special attention being given to the viral protease. The other viral proteins are the subject of individual articles in the journal. Together, these papers highlight current status of drug discovery efforts for flavivirus diseases and suggest promising areas for further research.
