| Outline of Final Research Achievements |
C5-curcuminoids are antitumor curcumin analogues bearing a reactive cross conjugated dienone structure. Dienone moiety is thought to be essential for antitumor activity and act as a Michael acceptor, which is traditionally avoided by medicinal chemists. Focusing on the dienone system, we monitored Michael reaction and retro Michael reaction between GO-Y030 and cysteamine by 1H-NMR spectroscopy method. In addition, we synthesized C5-curcuminoid thiol-adducts and evaluated their cell growth inhibitory activity against human colon cancer HCT116. The cytoxicity of C5-curcuminoid thiol-adduct was almost comparable with that of GO-Y030, highlighting their potential as prodrugs. Our results indicated that C5-curcuminoids react with cysteine thiol in a reversible manner, which is considered as important intracellular behavior of C5-curcuminoid.
