摘要:
Certain known and novel pyruvate derivatives are particularly active in restoring or preserving metabolic integrity in oxidatively competent cells that have been subjected to oxygen deprivation. These pyruvate-derived compounds include, but are not limited to oximes, amides, pyruvate analogues, modified pyruvate analogues, esters of pyruvate (e.g., polyol-pyruvate esters, pyruvate thioesters, glycerol-pyruvate esters and dihydroxyacetone-pyruvate esters). Such pyruvate derivatives (including single tautomers, single stereoisomers and mixtures of tautomers and/or stereoisomers, and the pharmaceutically acceptable salts thereof) are useful in the manufacture of pharmaceutical compositions for treating a number of conditions characterized by oxidative stress.

摘要:
Racemic or optically pure N-(4-cyano-3-trifluoromethylphenyl)-3-(4 -fluorophenylsulphonyl)-2-hydroxy-2-methylpropionamide of formula (I) is prepared by the following process: 2,3-dihydroxy-2-methylpropionic acid of formula (VII) is reacted with thionyl chloride to form 4-chlorocarbonyl-4-methyl-1,3,2-dioxathiolane-2-one of formula (VI), which is reacted with 4-cyano-3-trifluoromethylaniline. The resulting 4-{[4-cyano-3-(trifluoromethyl)anilino]carbonyl}-4-methyl-1,3,2-dioxathiolane-2-one of formula (V) is hydrolysed to form N-[4-cyano-3-(trilfuoromethyl)phenyl]-2,3-dihydroxy-2-methylpropionamide of formula (IV), which is sulfonylated with a sulfonyl halogenide of formula R-SO2-X, in a halogenated hydrocarbon solvent in the presence of a tertiary amine base. The sulphonic ester derivative of formula (III) obtained is reacted with 4-fluorothiophenol in the presence of a base to give a thioether of formula (II) which is oxidized using an inorganic peroxy compound or aqueous hydrogen peroxide.
