Synthesis and antioxidant activities of 3,5-dialkoxy-4-hydroxycinnamamides
摘要:
A series of 3,5-dialkoxy-4-hydroxycinnamamides 6 and 7 was synthesized, and their antioxidant activity was assessed using the thiobarbituric acid reactive substance (TBARS) assay. Interestingly, cinnamamides with longer alkoxy groups on the C-3 and C-5 positions display enhanced inhibition, and most of the compounds in the series tested exhibit excellent lipid peroxidation inhibitory activities. Some cinamamides bearing hexyloxy or 2,6-di-tert-butyl-4-methyl phenol groups have submicromolar inhibitory activities. (c) 2008 Elsevier Ltd. All rights reserved.

The present invention relates to 4-hydroxycinnamamide derivatives as antioxidants and pharmaceutical compositions containing them. More particularly, it relates to 4-hydroxycinnamamide derivatives showing superior antioxidant activity compared to the known antioxidant compounds, their pharmaceutically acceptable salt, and pharmaceutical compositions containing them. It can be usefully used in treating neurodegerative diseases such as aging, cancer, diabetes, ischemic stroke, Parkin's disease, dementia and Huntinton's disease.
