<p>Anthocyanins have been studied as potential antimicrobial agents against <i>Helicobacter pylori</i>. We investigated whether the biosynthesis and secretion of cytotoxin-associated protein A (CagA) and vacuolating cytotoxin A (VacA) could be suppressed by anthocyanin treatment <i>in vitro</i>. <i>H. pylori</i> reference strain 60190 (CagA<sup>+</sup>/VacA<sup>+</sup>) was used in this study to investigate the inhibitory effects of anthocyanins; cyanidin 3-O-glucoside (C3G), peonidin 3-O-glucoside (Peo3G), pelargonidin 3-O-glucoside (Pel3G), and malvidin 3-O-glucoside (M3G) on expression and secretion of <i>H. pylori</i> toxins. Anthocyanins were added to bacte...
