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体药物分子连接到载体分子上,并通过延长母体药物在给患者用药后的释放和吸收时间,以及提供比母体药物本身更长的单位剂量作用时间,来实现上述目的。原药共轭物适用于持续给药杂芳族、内酰胺-酰胺、亚胺、磺胺、氨基甲酸酯、脲、苯甲酰胺、酰苯胺、环酰胺和叔胺母药,这些母药在酰胺氮或氧原子上被易变醛连接的原药分子取代。原药的载体基团可以是疏水性的,以降低母药在生理条件下的极性和溶解度。
