complexes of 3-[{3-(3'-bromo phenyl)}-prop-2-enoyl]-4-hydroxy-6-methyl-2h-chromen-2-one with cu(ii), ni(ii), fe(ii), co(ii) and mn(ii) have been synthesized and characterized using elemental analysis, ir spectra and conductivity measurements. these studies revealed that they are having octahedral geometry of the type [ml2 (h2o)2]. in-vitro antimicrobial activity of all synthesized compounds and...

one of the methods to enhance bio-accessibility of drugs like acridone and its oxime is toform inclusion complexes with β-cyclodextrin. the formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. the aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. the studyof thermodynamic parameters like δg,...

An antimicrobial peptide (AMP) of the cecropin family was isolated by HPLC from plasma of the insect pest, Spodoptera frugiperda. Its molecular mass is 3910.9 Da as determined by mass spectrometry. Thanks to the EST database Spodobase, we were able to describe 13 cDNAs encoding six different cecropins which belong to the sub-families CecA, CecB, CecC and CecD. The purified peptide identified as...

The novel oxazolidinone tedizolid phosphate is in late-stage development for acute bacterial skin and skin structure infections (ABSSSIs). Preclinical and phase 1 trials have shown that 200-mg once-daily tedizolid phosphate dosing achieves the appropriate pharmacokinetic goals for optimal antimicrobial effect, and a randomized phase 2 dose-ranging trial confirmed that tedizolid phosphate may be...

BACKGROUND Antimicrobial resistance (AMR) is a recognized threat to global public health. Increasing AMR and a dry pipeline of novel antimicrobial drugs have put AMR in the international spotlight. One strategy to combat AMR is to reduce antimicrobial drug consumption. Governments around the world have been experimenting with different policy interventions, such as regulating where antimicrobia...

Medical researchers at Department of Infectious Diseases and Microbiology at the Stamford Hospital in Stamford, CT are studying episodes of central venous catheter-related bacteremia (CVCB) that have become common events in patients with long-term indwelling central venous catheter use. Since no standardized treatment of CVCB exists, novel approaches have been used to salvage infected catheters...

conclusions the excellent antimicrobial activities of the tested eos might be due to their major phenolic or alcoholic monoterpenes with known antimicrobial activities. hence, these eos can be possibly used as an antimicrobial agent in treatment and control of oral pathogens. results the tested eos inhibited the growth of examined oral pathogens at concentrations of 0.015-16 µl/ml. among the ex...

conclusions the results of the present study indicate that brazilian propolis demonstrated in vitro anti-microbial efficacy against s. mutans and c. albicans. results the antimicrobial efficacy of hexidine against s. mutans and e. coli was higher compared to that of c. albicans. the brazilian propolis (p) mr showed antimicrobial action against s. mutans and c. albicans. the antimicrobial effica...
