Development of improved inhibitors of wall teichoic acid biosynthesis with potent activity against Staphylococcus aureus

A small molecule (1835F03) that inhibits Staphylococcus aureus wall teichoic acid biosynthesis, a proposed antibiotic target, has been discovered. Rapid, parallel, solution-phase synthesis was employed to generate a focused library of analogs, providing detailed information about structure-activity relationships and leading to the identification of targocil, a potent antibiotic.
