主 题：Water-soluble propolis Greit 120 HuIFN-αN3 anti-influenza activity ribavirin ID_(50)
摘 要：Influenza virus affects the respiratory tract in humans causing a range of distinct manifestations including fever, nasal secretions, cough, headaches, muscle pain and pneumonia, which could become violent and severe. It was found that influenza A viruses remain resistant to amantadine and rimantadin with high level of oseltamvir resistance. Therefore, there is a need for constant improvement of drugs active against resistant influenza viruses. Propolis has anti-influenza activity both in vitro and in vivo. Human leukocyte interferon （HuIFN-αN3） is a multi-subtype protein that displays an antiviral activity against influenza virus. In this study we elucidated the anti-influenza activity of the mixes of water-soluble propolis （WSP） （Greit 120） and HuIFN-αN3 at different ratios. Greit 120 polyphenols, total phenol acids and bioflavonoid were characterized by HPLC-UV-ESI-MS504971 and HuIFN-αN3 by reverse-phase high-performance liquid chromatography （RP-HPLC）. Influenza A and B viruses were separately added to the LLC-MK2 cells treated with WSP （Greit 120） and HuIFN-αN3 alone or in proportions 1：1, 1：2 and 2：1. Plates were incubated and cytopathic effect was determined. The best results （ID50） were obtained with the mix of 10% WSP and HuIFN-αN3 in proportion 1：2, showing ID50 at 12 ± 0.2 μg/mL and 19 ± 0.6 μg/mL for influenza A and B viruses, respectively. When comparing anti-influenza activity of WSP （Greit 120）/HuIFN-αN3 with that of ribavirin, it was found that 1：2 was the optimal ratio for WSP （Greit 120）/HuIFN-αN3 （0.5 and 0.6 for influenza A and B, respectively）. This new formulation of WSP （Greit 120） and HuIFN-αN3, showing better anti-Influenza activity, will definitely improve its application in flu infections.
