Research Abstract |
We carried out screening of anti-mycobacterial compounds from polyphenols. Some polyphenols suppressed proliferation of Mycobacterium tuberculosis growing in macrophages at lower concentrations than those suppressed in 7H9 culture medium. These facts indicate that these polyphenols possess bacteriostatic effects against M. tuberculosis via activation of host immunity. These data suggest use of the polyphenols for prevention and treatment of tuberculosis.
