title: Syntheses of Curcumin Bioconjugates and Study of Their Antibacterial Activities against beta-Lactamase-Producing Microorganisms.
abstract: In the present study curcumin bioconjugates, viz. di-O-glycinoylcurcumin (I), di-O-glycinoyl-C(4)-glycylcurcumin (II), 5'-deoxy-5'-curcuminylthymidine (5'-cur-T) (IV), and 2'-deoxy-2'-curcuminyluridine (2'-cur-U) (V) have been synthesized and characterized by elemental analysis and (1)H NMR. The turmeric peptide (Tp) was isolated from the aqueous turmeric extract of the turmeric rhizome. The antibacterial activity of these four bioconjugates and also of the turmeric peptide and sodium salt of curcumin (III) have been tested particularly for beta-lactamase-producing microorganisms.
