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, and/or various fused ring systems with the benzene ring at the 4′,5′ or 5′,6′ positions.
本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剂。其中一种形式的类似物在25位点上乙酰化,如利福霉素。另一种形式的类似物在25位点上去乙酰化。还有其他形式,包括苯并噁唑利福霉素、苯并噻唑利福霉素和苯并二唑利福霉素类似物在苯环的不同位置上衍生出各种融合环系统,包括苯环在4'、5'或5'、6'位置上的3'-羟基类似物。
