SYNTHESIZING DERIVATIVES FROM CYCLOPENTANONE ANALOGUE CURCUMIN AND THEIR TOXIC, ANTIOXIDANT AND ANTI-INFLAMMATORY ACTIVITIES

Abstract

Three types of cyclopentanone derivatives have been synthesized from aromatic aldehyde and ketone derivatives undera base condition through aldol condensation. These cyclopentanone products were 2,5-dibenzylidene-cyclopentanone(a), 2,5-bis-(4-hydroxy-benzylidene)-cyclopentanone (b), and 2,5-bis-(4-hydroxy-benzylidene)-cyclopentanone (c)which has a yield of 63-99%. The chemical structure of these compounds were determined using UV, IR and NMRspectroscopy. In order to clarify the role of hydroxyl and amine moieties, toxic, antioxidant and anti-inflammatoryactivities were carried out. The toxic test indicated that the compounds showed strong toxicity. In addition, the presenceof hydroxyl and amine groups on both rings of curcumin increased the antioxidant and anti-inflammatory activities
