The compounds include substituted rifamycin derivatives in which a quinolone carboxylic acid pharmacophore is covalently bonded to a benzoxazinorifamycin or a spiropiperidinorifamycin. The rifamycin derivatives are useful as antimicrobial agents and are effective against a number of human and veterinary Gram positive and Gram negative pathogens. The advantage of the inventive compounds is that both the rifamycin and quinolone antibacterial pharmacophores are co-delivered with matched pharmacokinetics to the targeted pathogens of interests. Delivery of multiple antibacterial pharmacophores simultaneously to the targeted pathogens has the maximum chance of achieving synergy and minimizing the development of resistance to the antibiotics given.
这些化合物包括取代利福霉素衍生物,其中喹诺酸类药理团与苯并噁唑利福霉素或螺环哌啶利福霉素共价键合。利福霉素衍生物可用作抗微生物剂,对多种人类和兽医革兰氏阳性和革兰氏阴性病原体具有有效作用。这些创新化合物的优点是利福霉素和喹诺酸类抗菌药理团均具有匹配的药代动力学,可同时传递到感兴趣的靶病原体。同时向靶病原体传递多种抗菌药理团具有最大的协同作用和最小化抗生素耐药性发展的机会。
