  Synthesis and antibacterial evaluation of a novel series of rifabutin-like spirorifamycins

  摘要：

  A novel series of spirorifamycins was synthesized and their antibacterial activity evaluated both in vitro and in vivo. This new series of rifamycins shows excellent activity against Staphylococcus aureus that is equivalent to rifabutin. However, some compounds of the series exhibit lower MICs than rifabutin against rifampin-resistant strains of S. aureus. Further, compound 2e exhibits comparable efficacy in vivo in a murine model of S. aureus septicemia model following administration by either oral or parenteral dosing routes.
