  • Significance Small molecule probes have proved indispensable in dissecting bacterial systems. Their combinations have further expanded their utility as tools by enabling the study of interacting pathways. As such, screens for synergy between compounds have been widely used to reveal functional connections among cellular components. The utility of antagonism, however, has largely been overlooked. This study highlights the value of antagonistic interactions in elucidating genetic networks and mechanisms of drug action. Herein, we report on the discovery of clomiphene, an inhibitor of bacterial cell wall synthesis, uncovered through a systematic screen for antagonism. The discovery of clomiphene shed light on the pathways of cell wall biogenesis and, importantly, represents a new promising lead for the fight against infection.
