Antioxidant activity of NSAID hydroxamic acids.
In the present study, seven hydroxamic acid derivatives of nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, fenoprofen, ketoprofen, indomethacin and diclofenac) were found to possess significant antioxidant, radical scavenging and metal chelating activities. The most active antioxidant and radical scavenger was N-methylhydroxamic acid of diclofenac (ANT = 88.0% and EC50 = 60.1 microg m...
متن کاملAntimicrobial activity of some hydroxamic acids.
Several hydroxamic acids, viz., N-benzyl-N'-hydroxysuccinamide (BHS), poly[alpha,beta-(N-hydroxy)-DL-aspartamide] (PHA), poly[alpha,beta-(N-hydroxy-N-methyl-DL-aspartamide)] (PMHA) and poly[alpha,beta-(N-hydroxy)-DL- aspartamide]/poly[alpha,beta-(N-2-hydroxyethyl)-DL-aspartamide] (PHA-PHEA 1:1) were prepared and screened for their antimicrobial activity. Ten Gram-positive and 7 Gram-negative sp...
متن کاملMutagenicity and antibacterial activity of hydroxamic acids.
Hydroxamic acids demonstrated mutagenic and antibacterial activities. These activities appear to be dependent on the hydroxamic acid function and are probably due to the interaction with deoxyribonucleic acid.
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...
New complexes of peroxidases with hydroxamic acids, hydrazides, and amides.
Horseradish peroxidase forms spectroscopically distinct, reversible complexes with hydroxamic acids (R-CONHOH), hydrazides (RCO-NHNH2), amides (RCONH2), and oc-hydroxyketones (RCO--CHsOH). Binding of these compounds to the enzyme depends on the polar and steric character of R and the hydrogen bonding capacity of-COX-Y (X-Y = NH-OH, NH-NH,, NH-H, CH,OH). Hydroxamate anions and hydrazide cations ...
