The present invention discloses certain novel prodrugs of florfenicol and/or of florfenicol analogs, including prodrugs of salts pharmaceutically acceptable salts of florfenicol and its analogs, including nitrogen-containing esters of the secondary alcohol group of florfenicol and of its analogs, and pharmaceutically acceptable salts thereof, compositions containing them, and methods of administering them to subjects. In particular embodiments the prodrugs are sufficiently water-soluble to serve the functions needed of a water-soluble prodrug of florfenicol or of a water-soluble prodrug of a florfenicol analog. A certain subclass of the compounds also possesses the hydrolytic stability needed to maintain the prodrug in solution in the subject's system until appropriate conditions exist when the prodrug can hydrolyze, releasing florfenicol or the florfenicol analog in question.
本发明揭示了某些新型氟苯菲酚和/或氟苯菲酚类似物的前药,包括氟苯菲酚及其类似物的可接受药用盐的前药,包括氟苯菲酚和其类似物的次级醇基的含氮酯前药及其药用可接受盐,含有它们的组合物以及将它们用于给予受试者的方法。在特定实施例中,这些前药具有足够的水溶性,以发挥氟苯菲酚或氟苯菲酚类似物的水溶性前药所需的功能。某些化合物的亚类也具有水解稳定性,以保持前药在受试者的系统中溶解,直到存在适当的条件使前药水解,释放所需的氟苯菲酚或氟苯菲酚类似物。
