2,6-Dimethyl-4-(4'-hydroxy-3',5'-di-t-butylphenyl)-1,4-dihydropyridine derivatives, process for their preparation and their use as free radical scavengers.

摘要

The invention relates to 2,6-dimethyl-4-(4'-hydroxy-3',5'-di- t-butylphenyl)-1,4-dihydropyridine derivatives of formula (I): <IMAGE> where: - R1 is a substituted or unsubstituted, linear, branched or cyclic C1-C5 alkyl radical; - R2 is a hydrogen atom or an unsubstituted or substituted, linear or branched C1-C5 alkyl radical, their isomers and their pharmaceutically acceptable addition salts with inorganic or organic acids, a process for preparing them and their use as free radical scavengers.
