  通过生物膜改善递送。32.各种雌二醇衍生物的脑靶向递送系统的合成和生物学活性。

  摘要：

  在平衡吡啶鎓盐氧化还原互变中基于二氢吡啶的脑靶向递送系统被合成为雌二醇，3-苯甲酸雌二醇和乙炔雌二醇。最初的生物学评估表明，虽然通过血清LH抑制测量到，所合成的所有四种化合物都发挥着中枢的雌激素活性，但只有基于17-取代的雌二醇和乙炔雌二醇的递送系统显示出延长的作用（大于12天）。乙炔雌二醇的17-（1-甲基-1,4-二氢烟酸酯）在各种测定中的行为与前述雌二醇类似物相似。在大鼠中进行的组织分布研究表明，施用乙炔雌二醇衍生物可导致中枢神经系统（CNS）中较高的相应吡啶鎓盐持续水平，而氧化代谢产物的血液水平迅速下降。持续的大脑水平与乙炔雌二醇的延长释放有关。到处理后24小时，通过HPLC在血液中未发现乙炔雌二醇，而在CNS中检测到超过20 ng / g的组织水平。这种增强的中央递送提供了剂量和时间依赖性的LH抑制，这表明与相应的雌二醇衍生物相比，其效力增加了三至五倍。HPLC在血液中未发现乙炔

  Inclusion complexes of hydroxypropyl-.beta.-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 reodox 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.
