  Antidyslipidemic and antioxidative activities of 8-hydroxyquinoline derived novel keto-enamine Schiffs bases

  摘要：

  8-Hydroxyquinoline when subjected to Duff reaction resulted in the formation of unexpected 7-methylaminomethylene-8-oxo-7, 8-dihydroquinoline-5-carbaldehyde 2, which existed in the keto-enamine form, in which the aromaticity of the relevant ring was disrupted, which upon subsequent treatment with various primary amines resulted in its nucleophilic substitution of aliphatic methyl amine. These interesting novel derivatives were evaluated in vitro for their antioxidant and in vivo for their anti-dyslipidemic and post-heparin lipolytic activities. Compound 6 was found to be most active anti-dyslipidemic and antioxidative agent in this series, respectively, and thus represent a new class of promising lead. (C) 2008 Elsevier Masson SAS.
