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 νg/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 νM.
本发明涉及用于预防或治疗分枝杆菌感染的化合物、组合物及方法。所述化合物包括天然存在的和合成的双
黄酮、
黄酮、
查尔酮以及类似
查尔酮的化合物。这些化合物经过筛选以确定其抗分枝杆菌活性。在显示出抗分枝杆菌活性的化合物中,有八种被鉴定为特别有效,能够在12.5 µg/mL的浓度下抑制结核杆菌(Mtb)生长超过90%。这些优选化合物的实际最小抑菌浓度(MIC),即能够抑制99%菌悬液生长的最低浓度,范围为6.8至48.3 µM。
