ABSTRACT
1-(2,4-Dichlorophenyl)-2-phenylpropen-1-one (2) is identified as a potent antibacterial agent. A compound, 2-chloro-1-(2,4-dichlorophenyl)-3-(1H-imidazol-1-yl)-2-phenylpropan++ +-1-one (5) has been designed with the intention of its acting as a pro-drug, liberating the lethal species 2 specifically within the target anaerobic bacterial cell following bioreduction by bacterial ferredoxin or related electron transfer proteins. The synthesis and biological activity of 5 is described and compared with the activities of the analogous alpha-bromo ketone 6 and alpha-fluoro ketone 7. Synthesis of 6, 7, and the corresponding alpha-hydroxy ketone 11 is also described.
