Antibacterial Activity and Specificity of the Six Human -Defensins
We developed a kinetic, 96-well turbidimetric procedure that is capable of testing the antimicrobial properties of six human -defensins concurrently on a single microplate. The defensins were prepared by solidphase peptide synthesis and tested against gram-positive bacteria (Staphylococcus aureus and Bacillus cereus) and gram-negative bacteria (Enterobacter aerogenes and Escherichia coli). Anal...
متن کاملAntibacterial Activity of Medicinal Plant Extracts
The present study aimed at evaluating the in vitro antimicrobial activity of methanolic extracts of some medicinal plants against Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus and Enterococcus sp. The methanolic extract of Caryophyllus aromaticus presented the highest anti-S. aureus activity and was effective against all bacterial strains tested.
متن کاملAntibacterial activity of Brazilian Amazon plant extracts.
Infections caused by multiresistant bacteria are a widespread problem, especially in intensive care units. New antibiotics are necessary, and we need to search for alternatives, including natural products. Brazil is one of the hottest spots in the world in terms of biodiversity, but little is known about the chemical and pharmacological properties of most of the plants found in the Amazon rain ...
متن کاملBasic insight on plant defensins
Defensins are small cysteine-rich peptides with antimicrobial activity. Plant defensins have a characteristic threedimensional folding pattern that is stabilized by eight disulfide-linked cysteines. This pattern is very similar to defense peptides of mammals and insects, suggesting an ancient and conserved origin. Functionally, these proteins exhibit a diverse array of biological activities, al...
متن کاملCysteine-stabilized αβ defensins: From a common fold to antibacterial activity
Antimicrobial peptides (AMPs) seem to be promising alternatives to common antibiotics, which are facing increasing bacterial resistance. Among them are the cysteine-stabilized αβ defensins. These peptides are small, with a length ranging from 34 to 54 amino acid residues, cysteine-rich and extremely stable, normally composed of an α-helix and three β-strands stabilized by three or four disulfid...
