Abstract

The derivatives of curcumin are secondary metabolites belonging to the phenolicgroup. Some of them were reported to have biological activities such as anti-inflammatory, anticancer and antioxidant activities. In this study, a curcumin of(3E,5E)-3,5-bis(2’-hidroxybenzilidin)-1-metilpiperidin-4-onefrom1-methyl-4-piperidinone with 2-hydroxy benzaldehide has been successfully synthesized usingmicrowave irradiation method with NaOH (20%) as catalyst. Reaction was carried outfor 1 minute at 180 watt. The compound resulted was in the form of yellow crystalwith a yield of 72%. The compound was characterized by measuring its melting point,identifying by TLC, and elucidated by UV-Vis, FT-IR, MS, 1 H NMR, and 13 C NMR.Our result showed that the compound had the targeted molecule structure. Antibacterialtest was carried out using the agar diffusion method against Staphylococcus aureus,Escherichia coli, Bacillus subtilis, and Salmonella enteritidis. Overall, inhibition zoneranged from 6.5 to 10 mm and showed a very weak activity.

Abstract

Curcumin is one of secondary metabolites with phenolic group which was known tohave various biological activities such as antimicroba, anticancer, antioxidant, antitumorand anti-inflammatory activities. In this research, curcumin analog of 1-benzil-4-piperidone derivative was synthesized using microwave irradiation with catalyst NaOH.The rendement (YN 2 ) resulted 99.39%. All compounds were characterized using UVspectrophotometer, IR spectrophotometer, 1 H NMR, and 13 C NMR spectrometers. Theantibacterial activity was evaluated using the agar diffusion method. Antibacterialactivity test was carried out at concentrations of 20, 30, 40, 50 , and 60 mg/disc againstGram positive bacteria (Staphylococcus aureus and Bacillus subtilis) and Gramnegative bacteria (Escherichia coli and Salmonella enteritidis). YN 2 compoundsobtained showed different antibacterial activity against different bacteria.
