Antioxidant behaviour of thia fatty acids

, p. 647 - 653 (2002)
Eight thia fatty acids and other sulfides have been studied as inhibitors of autoxidation of arachidonic acid. The inhibitors extend the lag phase of the oxidation, to varying degrees. A carboxyl group in the vicinity of the sulfur reduces the antioxidant activity, while unsaturated sulfides are more effective than their saturated analogues. The results are consistent with the sulfides acting to reduce fatty acid hydroperoxides, which otherwise accumulate during the early stages of reaction and propagate the free-radical oxidation process.
An improved and green preparation of 3-(alkylthio)propionic acids

An efficient, facile microwave-assisted synthesis has been developed for the preparation of unsymmetrical sulfide derivatives from 3-mercaptopropionic acid and a wide variety of alkyl, allyl or aryl chlorides or bromides. The synthesis performed in ethanol at 80 or 120 °C using sodium hydroxide as a base, selectively without an offensive smell, generates 3-(alkylthio)propionic acids in good yields. Effects of reaction components, temperature, and the heating technique on the formation of the product and side-products were studied.

S-Alkylthiocarboxylic acids and their potassium salts were prepared by photoaddition of α-olefins (C10, C12, and C14) with mercapto carboxylic acids such as thiomalic acid, triopropionic acid, and thioglycolic acid.The physicochemical solution properties and thermal stabilities for three series of thiosurfactants were evaluated.S-Alkylthiocarboxylic acids that contain bridged S-bonds provide excellent thermally stable surfactants, and their alkaline salts exhibit good surface activity.KEY WORDS: α-Olefin, mercapto carboxylic acid, photoaddition, S-alkylthiocarboxylic acid, S-alkylthioglycolic acid, S-alkylthiomalic acid, S-alkylthiopropionic acid, surface activity, thermal stability.
