Inclusion complexes of hydroxypropyl, hydroxyethyl, glucosyl, maltosyl and maltotriosyl derivatives of .beta.- and .gamma.-cyclodextrin with the reduced, biooxidizable, blood-brain barrier penetrating, lipoidal forms of dihydropyridine.revreaction.pyridinium salt redox systems for brain-targeted drug delivery provide a means for stabilizing the redox systems, particularly against oxidation. The redox inclusion complexes also provide a means for decreasing initial drug concentrations in the lungs after administration of the systems, leading to decreased toxicity. In selected instances, complexation results in substantially improved water solubility of the redox systems as well.
羟丙基、羟乙基、葡萄糖基、麦芽糖基和麦芽三糖基衍生物与β-和γ-环糊精的包含复合物,与还原的、可生物氧化的、能穿透血脑屏障的、脂质形式的二氢吡啶.反应.pyridinium盐氧化还原系统形成脑靶向药物输送的一种手段,用于稳定氧化还原系统,特别是对抗氧化作用。氧化还原包含复合物还提供了一种减少系统给药后肺部初始药物浓度的手段,从而降低毒性。在某些情况下,复合作用显著提高了氧化还原系统的水溶性。
