The present invention can inhibit dihydrofolate reductase in a microorganism. In some aspects, it may also suppress pigment formation in gram negative bacteria. The suppression of pigment formation can also mediate virulence suppression on other Gram negative bacteria. As such, the compounds may be used for microbial infections. The compounds can potentiate the effects of one or more antimicrobial agents when co-administered. Compositions including the compounds are provided. The composition can further include at least one antibiotic.
