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.
这项发明涉及利福霉素类似物,可用作治疗或预防各种微生物感染的治疗药物。在一种形式中,这些类似物在25位点上乙酰化,就像利福霉素一样。在另一种形式中,这些类似物在25位点上去乙酰化。在其他形式中,苯并噁唑利福霉素、苯并噻唑利福霉素和苯并二唑利福霉素类似物在苯环的各个位置上进行衍生化,包括3'-羟基类似物、4'-和/或6'卤代和/或烷氧基类似物,以及各种包含环胺基团的5'取代基。
