Abstract

Chloroquine is a 9-aminoquinolone with well-known anti-malarial effects. It has biochemical properties that could be applied to inhibit viral replication. We report here that chloroquine is able to inhibit influenza A virus replication, in vitro, and the IC50s of chloroquine against influenza A viruses H1N1 and H3N2 are lower than the plasma concentrations reached during treatment of acute malaria. The potential of chloroquine to be added to the limited range of anti-influenza drugs should be explored further, particularly since antiviral drugs play a vital role in influenza pandemic preparedness.

摘要

氯喹是一种具有著名抗疟作用的9-氨基喹啉。它具有可用于抑制病毒复制的生化特性。我们在此报告,氯喹能够在体外抑制甲型流感病毒复制,并且氯喹对甲型流感病毒H1N1和H3N2的半数抑制浓度低于急性疟疾治疗期间达到的血浆浓度。鉴于抗病毒药物在流感大流行防范中发挥着至关重要的作用,氯喹添加到有限的抗流感药物范围中的潜力应进一步探索。
