title: Studies on antiviral glycosides. II. Chemical modifications of the envelope of Sendai virus.
abstract: Treatment of Sendai virus with p-azidophenyl-6-chloro-6-deoxy-beta-D-glucopyranoside (APG) caused chemical modification of the viral envelope under UV irradiation, which did not affect the hemagglutinin activity of the virus but inhibited the hemolytic activity. Also, the transfer of phospholipid from the viral envelope to chicken erythrocytes was measured using a spinlabel technique by electron spin resonance (ESR). In this experiment, the phospholipid transfer was depressed by the treatment with APG under the conditions which inhibited the hemolytic activity of the virus. These results suggest that APG bound covalently to lipid may disturb the specific interaction between the protein and the lipid of the viral envelope, resulting in the inhibition of the hemolytic activity. The effects of APG on the hemolysis and phospholipid transfer were compared with the results for the concanavalin A- and amphotericin B-treated viruses.
