Antimycobacterial activity of bacteriocins and their complexes with liposomes.
OBJECTIVES Bacteriocins (Bcn) are natural peptides that are secreted by several taxonomically distant bacteria and exert bactericidal activity against other bacterial species. Their capacity to inhibit growth of virulent Mycobacterium tuberculosis H37Rv was evaluated in this study. METHODS Five different Bcn were isolated and purified from bacterial culture supernatants, their amino acid sequ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
N-Alkoxyphenylhydroxynaphthalenecarboxamides and Their Antimycobacterial Activity.
A series of nineteen N-(alkoxyphenyl)-2-hydroxynaphthalene-1-carboxamides and a series of their nineteen positional isomers N-(alkoxyphenyl)-1-hydroxynaphthalene-2-carboxamides were prepared and characterized. Primary in vitro screening of all the synthesized compounds was performed against Mycobacterium tuberculosis H37Ra, M. kansasii and M. smegmatis. Screening of the cytotoxicity of the comp...
متن کاملReactions of thioamides with the ions of copper and antimycobacterial activity of the formed complexes
Owing to their physiological activity, thioamides are used in pharmacy [1], but no simple relation between the rate of their hydrolysis and microbial activity has been found [2]. Dithiocarbamates and their copper complexes which are chemically related to these substances also exhibit antimycobacterial activity [3]. Unfor tunately, only small attention has been hitherto paid to the complexes of...
متن کاملAntioxidant Activity and Electrochemical Properties of Tetradentate Schiff Bases and Their Cd(II) Complexes
This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...
