The antibacterial properties of sulfur containing flavonoids
摘要:
Some dithiocarbamic esters bearing a flavanone backbone, as well as their corresponding 1,3-dithiolium salts were tested against Staphylococcus aureus and Escherichia coli. The 1,3-dithiolium tricyclic flavonoids display good inhibitory properties against both Gram-positive and Gram-negative pathogens. (C) 2014 Elsevier Ltd. All rights reserved.

needed. In this paper, we present the cytotoxic effects of five tricyclic flavonoids, one of which was previously identified as a potent antimicrobial agent. Methods: All five derivatives were tested against human HOS and MCF7 cancer cell lines using a wound scratch assay. The cytotoxic properties of previously reported flavonoid 4a were also evaluated using the standard MTS (3-(4,5-dimethylthiazol-2

The synthesis of new 3-dithiocarbamic flavonoids has been accomplished by the reaction of the corresponding 2-hydroxyaryl dithiocarbamates with aminals. These flavonoids were obtained as a mixture of diastereoisomers, the anti isomer being the major one. The heterocyclization of these compounds provided novel tricyclic flavonoids bearing a 1,3-dithiolium-2-yl ring fused at the 3,4-carbon positions of the benzopyran moiety.
