Ramaria Fr. and Clavaria L. are the two major genera of coral mushrooms within families Gomphaceae and Clavariaceae, respectively. Besides having important role in forest ecology, some species of these are reported to possess high nutraceutical and bioactive potential. There is a hidden diversity of coral mushrooms in Northwestern Himalayas. Present studies describe the detailed biochemical pro...

− The aim of this research was to investigate the industrial application of Zanthoxylum schinifolium. Antibacterial activities of the n-hexane, methylene chloride (MC), ethyl acetate, and butanol fractions of Z. schinifolium were tested against Escherichia coli, Staphylococcus aureus and Helicobacter pylori. Among the fractions, the n-hexane and MC fractions showed the stronger antibacterial ac...

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...

background and objectives: dorema ammoniacum d. don (apiaceae) is a monocarpic plant endemic to central iran. the gum resin of this species is a known therapeutic agent in iranian, indian and western traditional medicines. the aim of the present study was to investigate essential oil constituents and evaluation of antioxidant and antibacterial activities of the essential oils and extracts of d....

the aim of this study was to assess the antibacterial activities of some medicinal plants extracts traditionally used in iran. hydroalcoholic extracts obtained from different parts of five plants including rosmarinus officinalis l. (rosemary), syzygium aromaticum l. (clove)., arctium lappa l. (burdock) , coriandrum sativum, myrtus communis with traditional medicinal use were examined for their ...

Antimicrobial host defense peptides are produced by all complex organisms as well as some microbes and have diverse and complex antimicrobial activities. Collectively these peptides demonstrate a broad range of antiviral and antibacterial activities and modes of action, and it is important to distinguish between direct microbicidal and indirect activities against such pathogens. The structural ...

Removing the bacteria, including Enterococcus faecalis, from the root canal is one of the important aims in endodontic treatment.We aimed to compare the antibacterial activity of Chlorhexidine with two natural drugs. The antibacterial activities of three different propolis extracts (alcohol concentrations: 0, 15, 40%) and Aloe vera gel on E. faecalis were compared using three methods: disk dif...

Crude extracts from olive leaves and arugula seeds were screened for its in vitro antibacterial activity. Antibacterial activity was determined by using disc diffusion method against three bacteria (, Staphylococcus aurous and Bacillus cereus). Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) have been determined. Gallic acid was used as a standard drug for th...

We report on the antibacterial activities of an 11 residue peptide (FQWQRNMRKVR) homologous to just over half the loop region of human lactoferricin. The peptide, in the form of a multiple antingen peptide (MAP), exerted signi cant antibacterial e ects against a broad spectrum of bacteria including MRSA. Lactoferricin is an iron-binding glycoprotein belonging to the transferrin family and found...
