ELABORATION OF CURCUMIN INTO DIKETONE MODIFIED ANALOGUES DEVOID OF NUCLEOPHILIC ADDITION CAPABILITY; IMPLICATIONS FOR THEIR ANTITUMOR AND CHEMOSENSIT…

2009

Curcumin (CUR), a polyphenolic compound extracted from Curcuma longa L.,can beconsidered as a good lead compound for the design of new drugs for the treatment of cancer and other therapeutic purposes. CUR is endowed with a diketone function, which appears to be important for its antitumor activity: also depending on the dose, the compound may show complex either pro-oxidant or anti-oxidant effects, which both may, at least in part, be linked to this structural moiety. In the lower concentration, "chemopreventive", range, CUR behaves mainly as an antioxidant; at higher concentrations, the a, b-unsaturated 1,3-diketone, as a Michael acceptor, can form adducts with the –SH groups and generate …

Supported ionic liquids. New recyclable materials for the L-proline-catalyzed aldol reaction

2006

New materials for L-proline recycling have been developed. These materials have been applied to the L-proline-catalyzed aldol reaction between acetone and several aldehydes. The L-proline has been supported on the surface of modified silica gels with a monolayer of covalently attached ionic liquid with or without additional adsorbed ionic liquid. Good yields and ee values, comparable with those obtained under homogeneous conditions, have been obtained especially with imidazolinium-modified and 4-methylpyridinium-modified silica gels. Moreover, these materials have been easily recovered by simple filtration and studies about their reuse have been carried out. These studies showed that these …
