UNLABELLED The ferulic acid (4-hydroxy-3-methoxy-cinnamic acid) is a phenolic compound with important antioxidant effects and which nowadays is being extensively studied for his potential indications in inflammatory and neurodegenerative diseases, hypertension, atherosclerosis, etc. AIM The synthesis of new ferulic acid compounds with potential(More)
BACKGROUND l-Arginine is a semi-essential aminoacid with important role in regulation of physiological processes in humans. It serves as precursor for the synthesis of proteins and is also substrate for different enzymes such as nitric oxide synthase. This amino-acid act as free radical scavenger, inhibits the activity of pro-oxidant enzymes and thus acts(More)
AIM To design new thiazolidin-4-ones derivatives and to evaluate their potential antioxidant effects using in vitro methods. MATERIAL AND METHODS New ethyl esters of the 2-(R-phenyl)-4-oxo-thiazolidin-3-yl propionic acid were synthesized using "one step reaction" between different aromatic aldehydes, thioglycolic acid and beta-alanine ethyl ester(More)
AIM To design new derivatives of aryl-propionic acid with potential antibacterial and antioxidant activity. MATERIAL AND METHODS New hydrazone of ibuprofen (2-(4-isobutylphenyl)propionic acid) have been synthesized by reaction of ethyl ester of ibuprofen with hydrazine hydrate and then condensation of corresponding hydrazide with various aromatic(More)
New thiazolidine-4-one derivatives based on the 4-aminophenazone (4-amino-2,3-dimethyl-1-phenyl-3-pyrazolin-5-one) scaffold have been synthesized as potential anti-inflammatory drugs. The pyrazoline derivatives are known especially for their antipyretic, analgesic and anti-inflammatory effects, but recently there were synthesized new compounds with(More)
New thiazolidine-4-one derivatives of 2-(4-isobutylphenyl)propionic acid (ibuprofen) have been synthesized as potential anti-inflammatory drugs. The structure of the new compounds was proved using spectral methods (FR-IR, 1H-NMR, 13C-NMR, MS). The in vitro antioxidant potential of the synthesized compounds was evaluated according to the total antioxidant(More)
AIM To design new hydrazones with pyrazolone structure with improved biological properties. MATERIAL AND METHODS New hydrazones of antipyrine have been prepared by reaction of 4-aminophenazone (4-aminoantipyrine) with chloracetylchoride and hydrazine hydrate and then condensation with various aromatic aldehydes. RESULTS The synthesized compounds were(More)
UNLABELLED Ibuprofen, an important nonsteroidal anti-inflammatory agent, is one of the most prescribed drugs for the treatment of pain and inflammation from various rheumatic diseases, but some side effects can occur on long-term use. AIM The method for synthesis optimization of new derivatives of Ibuprofen with thiazolidin-4-one moiety, with improved(More)
This work reports the design of [1,3,4]thiadiazolo[3',2':1,2]imidazo[4,5-c]quinolines using a Pictet-Spengler reaction. The scope of the reaction was achieved from 6-(2-aminophenyl)imidazo[2,1-b][1,3,4]thiadiazole derivatives and available aldehydes. A wide range of aldehyde was employed to examine the scope of the cyclization. In parallel, a mechanism(More)
