  Synthesis and Biological Evaluation of Analogs of Methyl Ursolate 3-O-β-Chacotrioside as H5N1 Viral Entry Inhibitors

  摘要：

  The earliest stage of influenza virus infection is the viral entry to the host cell. In our previous work, we discovered the first three small molecule H5N1 viral entry inhibitors 1-3. Here, based on saponin 3, methyl ursolate 3-O-beta-chacotrioside, several analogs were synthesized and evaluated to understand the structure-activity relationships of this type of compound on the H5N1 viral entry inhibitory activity. The preliminary studies demonstrated that unlike saponins 1 and 2, it is possible to reduce the 3-O-chacotriosyl residue of compound 3 to a disaccharide without affecting the viral entry activities significantly. The results obtained will render new clues to the understanding of the antiviral profile for these types of compounds.
