The present invention relates to compounds, compositions and methods for the prevention or treatment of mycobacterium infections. The compounds are naturally occurring and synthetic biflavonoids, flavonoids, chalcones and chalcone like compounds. The compounds were screened for anti-mycobacterium activity. Of the compounds showing anti-mycobacterium activity, eight were identified as particularly potent, exhibiting greater than 90% inhibition of the growth of Mtb at a concentration of 12.5 Πg/mL. The actual minimum inhibitory concentrations (MIC), defined as the lowest concentration inhibiting 99% of the inoculum, for the preferred compounds ranged from 6.8 to 48.3 ΠM.
