of new metronidazole–deoxybenzoinderivatives were synthesized and evaluated for their antimicrobial activityagainst Helicobacter pylori. Highly selective anti‐H. pyloriactivity was also observed in synthesized compounds. Compound 34 exhibited the most potentactivity, similar to the positive control amoxicillin. Furthermore, compounds 17 and 34 were able to significantly decrease H. pylori water
