Design and synthesis of curcumin-bioconjugates to improve systemic delivery.

Abstract

Di-O-glycinoyl curcumin (I), di-O-glycinoyl-C4-glycyl-curcumin (II), 5'-deoxy-5'-curcuminyl thymidine (5'-cur-T) (III) and 2'-deoxy-2'-curcuminyl uridine (2'-cur-U) (IV) have been synthesized and characeterised by elemental analysis & 1H NMR. The antibacterial activities of these four bioconjugates has been tested particularly for multiresistant micro-organisms. Best results are shown by I & IV. These bioconjugates serve dual purpose of systemic delivery as well as therapeutic agents against viral diseases.
