Recombinant DNA-produced human interferon-alpha 2 inhibited the replication of influenza A and B viruses in primary rhesus monkey kidney cells (RMK). Human interferon-alpha 2 interacted additively or synergistically with rimantadine hydrochloride or ribavirin in reducing the yield of clinical isolates of either H3N2 or H1N1 subtype influenza A viruses. The combination of human interferon-alpha 2 and ribavirin also inhibited the replication of an influenza B virus to a greater extent than either single agent. In addition to drug concentration, the virus inoculum and duration of culture were important variables in determining the degree of inhibition. Single drugs or combinations did not significantly inhibit the growth of uninfected RMK cells, which indicated that the observed interactions with respect to antiviral activity were not due to cell cytotoxicity.
重组DNA制备的人α-2干扰素可抑制甲型和乙型流感病毒在原代恒河猴肾细胞(RMK)中的复制。在降低H3N2或H1N1亚型甲型流感病毒临床分离株的产量方面,人α-2干扰素与盐酸金刚烷胺或利巴韦林呈相加或协同作用。人α-2干扰素与利巴韦林联合使用时,对乙型流感病毒复制的抑制程度也大于单一药物。除药物浓度外,病毒接种量和培养时间也是决定抑制程度的重要变量。单一药物或联合用药均未显著抑制未感染的RMK细胞的生长,这表明观察到的抗病毒活性相互作用并非由于细胞毒性。
