OBJECTIVE
Study on the antibacterial activity of Viola yedoensis and the antibacterial active compounds.
METHODS
The chemical compositions were isolated by means of solvent extraction, column chromatography on silica gel, sephadex LH-20 and crystallization. The antibacterial activities were tested
The emergence of rapidly evolving multidrug-resistant pathogens and a deficit of new compounds entering the clinical pipeline necessitate the exploration of alternative sources of antimicrobial therapeutics. Cyclotides revealed in Viola spp. are a class of highly stable, cyclic, and
Anti-microbial activity and phytochemical analysis of samples from the roots of Viola pilosa was studied against six strains of bacteria. Data indicated that the tested bacterial strain differed in its sensitivity to the root extracts of Viola pilosa. The results showed that Xanthomonas campestris,
Viola yedoensis is a component of traditional Chinese herb medicine for inflammatory diseases. Chemical constituents of V. yedoensis have been shown to possess antibacterial, anti-HIV, and anticoagulant effects in experimental research; however, their anti-inflammatory properties remain to be
OBJECTIVE
To determine the antibacterial activity of small cyclic plant proteins, i.e. cyclotides, and the importance of the surface exposed charged residues for activity.
METHODS
Prototypic cyclotides, including the Möbius kalata B1 and the bracelet cycloviolacin O2 (cyO2), were isolated using
Essential oil composition of the leaves of Viola odorata L. growing wild in Kashan, central Iran, was extracted by hydro distillation-solvent extraction method and analysed using GC-MS technique. The analysis revealed the presence of 25 identified compounds, representing 92.77% of the oil with
Common violet (Viola odorata L., Violaceae) has shown various medical applications. Current study aimed to compile a review over chemical composition and medicinal properties of this plant in modern phytotherapy and its related multipotential products from traditional Persian medicine (TPM).
OBJECTIVE
Cyclotides are mini-proteins that are synthesized via the ribosomal pathway. They have a variety of biological activities such as antimicrobial, antitumour, anti-HIV activities. Because of their various bioactivities and unique stability, they are suitable candidate in drug design
Cyclotides are cyclic plant polypeptides of 27-37 amino acid residues. They have been extensively studied in bioengineering and drug development contexts. However, less is known about the relevance of cyclotides for the plants producing them. The anti-insect larvae effects of kB1 and antibacterial
The antibacterial activity of extracts from species of plants used in the Chinese medicine, Zi Hua Di Ding (Viola yedoensis, V. prionantha, Corydalis bungeana and Gueldenstaedtia verna), was tested against Bacillus subtilis and Pseudomonas syringae using a bioautographic assay. The petroleum ether
Modification of metal surfaces with antimicrobial peptides is a promising approach to reduce bacterial adhesion. Here, cyclic peptides or cycloids, possessing remarkable stability and antimicrobial activities, were extracted and purified from Viola philippica Cav., and identified using mass
The recent increase in extensively drug-resistant bacterial pathogens and the associated increase of morbidity and mortality demonstrate the immediate need for new antibiotic backbones with novel mechanisms of action. Here, we report the development of the PepSAVI-MS pipeline for bioactive peptide
