The mission of the Influenza Antiviral Drug Search project is to find new drugs that can stop the spread of an influenza infection in the body. The research will specifically address the influenza strains that have become drug resistant as well as new strains that are appearing. Identifying the chemical compounds that are the best candidates will accelerate the efforts to develop treatments that would be useful in managing seasonal influenza outbreaks, and future influenza epidemics and even pandemics.

Hundreds of thousands of people around the world die each year as a result of influenza infections. If a particularly virulent strain emerges that is readily transmitted among humans, a pandemic can potentially kill millions of people. The influenza virus mutates rapidly and therefore new varieties of influenza appear each year. Influenza vaccines are designed to anticipate the strains likely to be prevalent for the next flu season but can often miss newly evolved varieties. While drugs such as oseltamivir (commercial name Tamiflu) and zanamivir (commercial name Relenza) help keep influenza from spreading in the body, they do not work for all types of influenza and new drug resistant forms of influenza evolve and cannot be treated with these drugs. When drug resistant strains emerge, manufacturers designing vaccines may not be able to respond quickly enough to prevent a large outbreak of the disease. This project will search for promising new drug leads that stop the replication of the influenza viruses within the body, potentially helping patients who are not immune to a particular form of influenza. The discovery of both broad-spectrum and specific antiviral drugs is expected to significantly improve global health.

全世界每年有数十万人死于流感感染。如果出现一种特别致命的毒株,并且很容易在人类之间传播,那么一场大流行病可能会导致数百万人死亡。流感病毒变异迅速,因此每年都会出现新的流感变种。流感疫苗旨在预测下一个流感季节可能流行的毒株,但往往会错过新进化的变种。虽然奥司他韦(商品名达菲)和扎那米韦(商品名称瑞伦扎)等药物有助于防止流感在体内传播,但它们并不是对所有类型的流感都有效,而且新的耐药性流感正在演变,无法用这些药物治疗。当耐药菌株出现时,设计疫苗的制造商可能无法足够快地做出反应,以防止疾病的大规模爆发。该项目将寻找有前景的新药线索,阻止流感病毒在体内的复制,有可能帮助对特定形式的流感没有免疫力的患者。广谱和特异性抗病毒药物的发现有望显著改善全球健康状况。

One promising approach to combat these viruses and prevent them from causing disease is to develop new drugs that inhibit neuraminidase (N1, N2, etc), NS1 protein, hemagglutinin, and possibly other targets that influenza needs to spread in the body. Using the known chemical structures of these target molecules, the project will perform virtual chemistry experiments and determine which of millions of known compounds attach to these target molecules in a manner that can disable or inhibit them, thus potentially keeping the influenza virus from spreading in the body. These experiments are performed using a program called AutoDock, from the Scripps Research Institute. This software is used for several other projects on World Community Grid. These include FightAIDS@Home, Discovering Dengue Drugs - Together, and Help Fight Childhood Cancer projects. Once drug candidates are identified using World Community Grid, then additional laboratory work, testing and ultimately drug trials will be required. This will likely not lead to any immediate treatments for influenza during the current H1N1 outbreak. However, influenza viruses cause recurrent seasonal disease outbreaks and have the potential for evolving into dangerous forms. Thus, proceeding on this project at this time will give us a better chance to be prepared for more serious outbreaks in the future.

对抗这些病毒并防止其致病的一种有希望的方法是开发新的药物,抑制神经氨酸酶(N1、N2等)、NS1蛋白、血凝素,以及流感在体内传播所需的其他靶点。利用这些靶分子的已知化学结构,该项目将进行虚拟化学实验,并确定数百万种已知化合物中的哪种以能够使其失效或抑制的方式附着在这些靶分子上,从而有可能阻止流感病毒在体内传播。这些实验是使用斯克里普斯研究所的一个名为AutoDock的程序进行的。该软件用于世界社区网格上的其他几个项目(包括FightAIDS@Home),共同研究登革热药物,帮助抗击儿童癌症项目。一旦使用世界社区网格确定了候选药物,就需要额外的实验室工作、测试和最终的药物试验。在当前H1N1流感爆发期间,这可能不会导致任何流感的即时治疗。然而,流感病毒会导致季节性疾病的反复爆发,并有可能演变成危险的形式。因此,此时进行这一项目将使我们有更好的机会为未来更严重的疫情做好准备。
