Background Rotavirus is the most prevalent cause of severe gastroenteritis, hospitalizations, and deaths among infants and young children, globally. No specific antiviral drug is available against rotavirus infection. Objective The current study aimed to assess the antiviral effect of human cathelicidin antimicrobial peptide LL-37 on rotavirus infection in vitro. Methods This study was con...
in this research, dried acetone:chloroform extract of aerial parts of e. denticulata as one of the endemic plants to iran, afforded a number of triterpenes and steroids including: betulin, 24-methylene-cycloart-3-ol, cycloart-23z-ene-3β,25-diol, cycloart-23z-ene-3β,25-diol, ergosta-8,24-dien-3-ol (obtusifoliol) and beta-sitosterol which were reported for the first time from this plant. the stru...
Silver nanoparticle (Ag NP)/chitosan (Ch) composites with antiviral activity against H1N1 influenza A virus were prepared. The Ag NP/Ch composites were obtained as yellow or brown floc-like powders following reaction at room temperature in aqueous medium. Ag NPs (3.5, 6.5, and 12.9 nm average diameters) were embedded into the chitosan matrix without aggregation or size alternation. The antivira...
The synthesis and antiviral activity of 1-N-palmitoyl- or 1-N-(3-hydroxytetradecanoyl)-kanamycin A derivatives (7,8) having various type of acyl substituents at the N-3" position were investigated. The structure-activity relationships between the antiviral activity and the substituent at the N-3" position is described. In this series, 3"-N-acetyl-1-N-palmitoyl-kanamycin A (7c) showed the excell...
