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 hydrochloride. The antioxidant potential of th...

Rhodanine (R) is a heterocycle having complexing properties for heavy metal (HM) ions. Considering the similar electron-donating character of diethylaminobenzene and azulene, electrochemical characterization (Z)-5-(azulen-1-ylmethylene)-2-thioxo-thiazolidin-4-one (R1) 5-(4 diethylamino-benzylidene)-2-thioxo-thiazolidin-4-one (R2) was performed to establish their common features. Chemically modi...

A series of rhodanine derivatives was prepared. The synthetic approach, analytical and spectroscopic data of all synthesized compounds are presented. Lipophilicity of all the discussed rhodanine derivatives was analyzed using the RP-HPLC method. The compounds were tested for their ability to inhibit photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts and reduc...

A new series of 2,3-disubstituted thiazolidin-4-ones were obtained by the condensation of appropriate amines with vanillin and mercapto acetic acid in the presence of DCC in anhydrous THF by microwave irradiation. The title compounds were investigated for their anticonvulsant activity. Among the test compounds, compound N-(2-(3hydroxy-4-methoxyphenyl)-4-oxo thiazolidin-3-yl) isonicotinamide (3)...
