licorice (glycyrrhiza glabra l.) is an important medicinal plant. in this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. bacillus subtilis, enterococcus faecalis, klebsiella pneumoniae, pseudomonas aeruginosa, staphylococcus aureus and escherichia coli, and candida albicans were used as test organisms...
In Drosophila, the response against various microorganisms involves different recognition and signaling pathways, as well as distinct antimicrobial effectors. On the one hand, the immune deficiency pathway regulates the expression of antimicrobial peptides that are active against Gram-negative bacteria. On the other hand, the Toll pathway is involved in the defense against filamentous fungi and...
Background and purpose: There is growing application of dendrimers in the world, therefore, this study was conducted to evaluate the effect of antibacterial properties of generation-2 and 4 poly (amidoamine) dendrimer (PAMAM) on some bacteria isolated from water resources. Materials and methods: Water samples were collected from drinking water resources. Bacteria were isolated and identified u...
Streptomyces cattleya produced a new cyclopentenedione antibiotic, G2201-C [C6H6O4(I)], which is moderatley active in vitro against Gram-positive bacteria, weakly active against Gram-negative bacteria, and inactive against fungi. G2201-C is toxic to mice.
the in vitro antimicrobial activity of the essential oil isolated from the aerial parts of cymbopogon olivieri (boiss.) bor, an aromatic grass of iran was tested against three gram-negative and four gram-positive bacteria and also three fungi. the results of the bioassays showed that the oil has a remarkable antimicrobial activity. bacillus subtilis and candida albicans were more sensitive to t...
Wide range of quinazolinone biological properties including: antibacterial, anticancer, and anti-inflammatory activities encouraged us to synthesis some fused quinazolinone derivatives. Anthranilic acid was condensed with chloro acylchloride followed by dehydration to form the benzoxazinone intermediate; subsequent addition of an amine provided the fused quinazolinones. Deoxyvasicinone which wa...
