Synthesis, biopharmaceutical characterization, antimicrobial and antioxidant activities of 1-(4′-O-β-d-glucopyranosyloxy-2′- hydroxyphenyl)-3-aryl-propane-1,3-diones

This research communication is toward the investigation of the antibacterial, antifungal and antioxidant activities of the synthesized compounds 1-(4′-O-β-d-glucopyranosyloxy-2′-hydroxyphenyl)-3- aryl-propane-1,3-diones (5a)-(5h). These compounds have been obtained by the interaction of α-acetobromoglucose with 1-(2′,4′- dihydroxyphenyl)-3-aryl-propane-1,3-diones (3a)-(3h) under anhydrous condition and at lower temperature. The structures of these newly synthesized O-β-d-glucopyranosides were established on the basis of chemical, elemental, and spectral analyses. Further, the compounds (5b), (5c), (5d) and (5g) showed potent antibacterial and antifungal activity. A good correlation was obtained between the theoretical predictions of bioavailability using Lipinski's rule-of-five and experimental verification. © 2011 Elsevier Masson SAS. All rights reserved.
