Human noroviruses are the primary cause of foodborne gastroenteritis. Potent and safe inhibitors are needed for the treatment/prophylaxis of norovirus infections. We demonstrate that Favipiravir [T-705, a drug in advanced clinical development for the treatment of infections with the influenza virus] inhibits in vitro murine norovirus replication. Time-of-drug addition studies reveal that T-705 exerts its activity at a time-point that coincides with onset of viral RNA synthesis, which is in line with the viral polymerase as the presumed target.
人类诺如病毒是食源性胃肠炎的主要病原体。因此,需要开发有效且安全的抑制剂来治疗/预防诺如病毒感染。本研究证明,法匹拉韦(T-705,一种用于治疗流感病毒感染的临床前药物)可抑制体外鼠诺如病毒复制。药物加入时间研究表明,T-705 的作用时间点与病毒 RNA 合成起始时间一致,这与聚合酶作为假定靶标一致。
