    • 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.
    • 本发明公开了氟苯尼考和/或氟苯尼考类似物的某些新型前药,包括氟代苯尼醇及其类似物的药学上可接受的盐的前药,包括氟苯尼考及其类似物的仲醇基的含氮酯和其可药用盐 含有它们的组合物,以及将它们给予受试者的方法。 在具体实施方案中,前药具有足够的水溶性,以用于氟苯尼考或氟苯尼考类似物的水溶性前药的水溶性前药所需的功能。 化合物的某一亚类也具有将前体药物保持在受试者系统的溶液中所需的水解稳定性,直到前药可以水解,释放所讨论的氟苯尼考或氟苯尼考类似物时才有适当的条件。

    • The present invention discloses prodrugs of chloramphenicol, thiamphenicol and their analogs, as well as pharmaceutically acceptable salts thereof, including nitrogen-containing esters of both alcohol groups. These prodrugs have the Formula (I), in which R, A a , L l , M m , X x , Y and R 3 are as defined in the claims. In certain embodiments these prodrugs are sufficiently water-soluble to serve the functions needed of a prodrug of chloramphenicol, thiamphenicol and their analogs. In one embodiment, a certain subclass of the compounds also possess 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 the active compound in question.
