The present invention accomplishes this by having multiple molecules of parent drugs attached to carrier moieties and by extending the period during which the parent drug is released and absorbed after administration to the patient and providing a longer duration of action per dose than the parent drug itself. Prodrug conjugates are suitable for sustained delivery of heteroaryl, lactam- amide-, imide-, sulfonamide-, carbamate-, urea-, benzamide-, acylaniline-, cyclic amide- and tertiary amine-containing parent drugs that are substituted at the amide nitrogen or oxygen atom with labile aldehyde-linked prodrug moieties. The carrier groups of the prodrugs can be hydrophobic to reduce the polarity and solubility of the parent drug under physiological conditions.
本发明通过将多个母药分子附着在载体基团上,并延长母药在患者服用后释放和吸收的时间,从而实现此目的,并提供每剂次比母药本身更长的作用时间。前药偶联物适用于异杂环、内酰胺、酰胺、磺酰胺、氨基甲酸酯、脲、苯甲酰胺、酰基苯胺、环状酰胺和三级胺含有母药,该母药在酰胺氮或氧原子处以不稳定的醛类前药基团取代。前药的载体基团可以是疏水性的,在生理条件下降低母药的极性和溶解度。
