چکیده
FR191512, a novel polyphenolic compound, inhibited the infectivity of influenza A virus in Madin-Darby canine kidney (MDCK) cells in vitro. Furthermore, FR191512 showed good in vivo anti-influenza activity in a mouse model of intranasal infection with influenza A virus. The cytotoxic activity of FR191512 against MDCK cells was very weak.

Anti-influenza Activity of a Novel Polyoxometalate Derivative (POM-4960)
There are many effective chemothereutic agents used in influenza disease which some of them inhibit virus replication by interfering with FluV (influenza virus) viral binding or its penetration into cell membrane. A series of polyoxometalates compounds such as POM-523 and PM-504 have been synthesized and have showed inhibitory effects on viruses. In this study we examined anti influenza activit...
متن کاملIsolation and Characterization of Melanin Producing Pseudomonas stutzeri Strain UIS2 in the Presence of l-tyrosine and Survey of Biological Properties of Its Melanin
Background: Melanin is a negative charge hydrophobic complex pigment. Melanin is produced naturally in bacteria to protect them against UV, free radicals and environmental stresses. Pigment production in bacteria has more advantages than other biosources due to its rapid growth, higher efficiency and easier extraction. The aim of this study was the isolation, biochemical and molecular identific...
