  • Publication number: 20100273765
    Abstract: The present invention features rifamycin analogs that can be used as therapeutics for treating or preventing a variety of microbial infections. In one form, the analogs are acetylated at the 25-position, as is rifamycin. In another form, the analogs are deacetylated at the 25-position. In yet other forms, benzoxazinorifamycin, benzthiazinorifamycin, and benzdiazinorifamycin analogs are derivatized at various positions of the benzene ring, including 3?-hydroxy analogs, 4?- and/or 6? halo and/or alkoxy analogs, and various 5? substituents that incorporate a cyclic amine moiety.
