    • The invention provides a method of sustained delivery of a tertiary amine-containing parent drug comprising administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile quaternary ammonium salts of tertiary amine-containing parent drugs (or tertiary imine-containing parent drugs) that are derivatized through aldehyde-linked prodrug moieties that reduce the solubility of the prodrug compound at a reference pH as compared to the parent drug. The physical, chemical and solubility properties of these derivatives can be further modulated by the choice of counterion X". In one embodiment, the present invention provides a prodrug compound of Formula I: where R 1 -R 5 are defined in the written description of the invention. The prodrug compounds of the invention can be used to treat any condition for which the tertiary amine-containing parent drug or tertiary imine-containing parent drug is useful as a treatment.
    • 本发明提供了一种持续递送含叔胺的母体药物的方法,包括向患者施用有效量的本发明的前药化合物,其中在给予患者时,母体药物从前药释放是持续释放的。 适用于本发明方法的前药化合物是通过醛连接的前药部分衍生的含叔胺的母体药物(或含叔亚胺的母体药物)的不稳定季铵盐,其将前药化合物的溶解度降低 与母体药物相比的参考pH。 这些衍生物的物理,化学和溶解性质可以通过选择抗衡离子X“进一步调节。在一个实施方案中,本发明提供式I的前药化合物:其中R 1 -R 5在本发明的书面描述中定义 本发明的前药化合物可用于治疗含有叔胺的母体药物或含三聚亚胺的母体药物作为治疗的任何病症。
