The antibacterial activity of coumarin per se and other 45 coumarin derivatives was tested against strains of Bacillus cereus MIP 96016, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, and Staphylococcus aureus ATCC 25923. The inhibitory effects of coumarins were affected by their substitution patterns. Osthenol (44) showed the most effective antibacterial activity against Gram-...
Alpha-melanocyte stimulating hormone (alpha-MSH) is an endogenous anti-inflammatory peptide reported to possess antimicrobial properties, however their role as antibacterial peptides is yet to be established. In the present study, we examined in vitro antibacterial activity of alpha-MSH against S. aureus strain ISP479C and several methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) S....
background: it is believed that bovine neutrophils contain several peptides and protein which exhibit antimicrobial activity against microorganisms such as fungi and bacteria. objectives: the purpose of this study was to isolate and purify a potential antibacterial protein from bovine neutrophil and test its anti bacterial activity. methods: neutrophils were isolated from bovine blood using dex...
Decarboxylated ciprofloxacin (3) has been reported in the literature to have antibacterial activities against Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Bacillus subtilis, Enterobacter cloacae, Serratia marcescens and especially potent activity against Escherichia coli. Herein, we report our syntheses of 3 and five additional decarboxylated fluoroquinolones (FQs)....
The prokaryotic type II topoisomerases (DNA gyrase and topoisomerase IV) and the eukaryotic type II topoisomerases represent the cellular targets for quinolone antibacterial and anticancer agents. Both enzymes effort the selectively shift from an antibacterial to an antitumor activity. In the search for potential molecule in the quinolones series, some of quinolone analogs displayed antibacteri...
