in the present study, a series of new substituted oxazolone derivatives (4a-4h) were synthesized by the erlenmeyer condensation of phthaloylglycylglycine with different aldehydes in the presence of anhydrous sodium acetate and acetic anhydride. the structure of newly-synthesized compounds were evaluated by elemental analyses and spectral ( uv-visible, ir, nmr, mass) studies. all the synthesized...

in this study bactericidal activity of a malodor neutralizer containing silver nanoparticles manufactured in iran has been tested. for this purpose different concentrations of the product encounter with staphylococcus aureus, pseudomonas aeruginosa and bacillus cereus then the activity were evaluated in different contact times. the products containing at least 200 ppm of silver nanoparticles we...

the antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. the useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. the aim of this study was to evaluate antibacterial activity properties of silver doped zinc...

Background and objectives:Plant essential oils are sometimes considered for use as antimicrobial agents in foods and medicines and they could be combined with other antimicrobial agents to strengthen the effect and/or reduce the required dose. This study was conducted to determine the chemical composition of the Ocimum basilicum, Salvia officinalis and Tra...

In recent years, scientists and researchers from all over the world pay much attention to carotenoid pigments as a substitute for antibiotics and synthetic chemical compounds with antioxidant property and the plants, various microorganisms including bacteria and algae are also capable of producing carotenoid pigments. In this research, the production of antimicrobial and antioxidant carotenoid ...

Lagenandra ovata (Linn.) Thw. syn. L. toxicaria Dalz. of Araceae family was evaluated for antibacterial activity against the Gram positive bacterium, Staphylococcus aureus and the Gram negative bacteria, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, P. vulgaris and Pseudomonas aeruginosa. Methanol extract of the rhizome and the oil fractions obtained from the methanol extract thro...

During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...

in this study, invitro evaluation of some iranian plants against staphylococcus aureus isolation of urinary tract infection by microtiterplate method. all 12 strains of staphylococcus aureus isolated from urine culture of hospitalized patients during the years 2012- 2013. minimum inhibitory concentration (mic) of plant extract and essential oilagainst bacteria were determined using micro diluti...

OBJECTIVES In this study we examined the in vitro synergistic effect of baicalin, the flavone constituent of Scutellaria spp., in combinations with oxytetracycline and tetracycline on the growth of Staphylococcus aureus. METHODS The MICs were determined by the broth microdilution method and the effect of combinations was evaluated according to the sum of fractional inhibitory concentration in...
