Design, synthesis and biological evaluation of 2-substituted 3-hydroxy-6-methyl-4H-pyran-4-one derivatives as Pseudomonas aeruginosa biofilm inhibitors
Drug-resistant bacteria associated with biofilm formation are rapidly on the rise, requiring novel therapeutic options to combat biofilm induced drug-resistance. In this study, a class of 3-hydroxy-2-(phenylhydroxy-methyl)-6-methyl-4H-pyran-4-one derivatives (1a-1e) were found by screening of an in-house compound library to be potential Pseudomonas aeruginosa biofilm inhibitors. Thirty one novel 2-substituted
