Considering the importance of PDE4D inhibition and the modulation of biometals in Alzheimer's disease (AD) therapeutics, we have designed, synthesized and evaluated a series of new clioquinol-rolipram/roflumilast hybrids as multitarget-directed ligands for the treatment of AD. In vitro studies demonstrated that some of the molecules processed remarkable inhibitory activity against phosphodiesterase
考虑到PDE4D抑制和生物金属在阿尔茨海默氏病(AD)疗法中的重要性,我们设计,合成和评估了一系列新的氯喹诺醇-咯利普兰/鲁氟司特杂合体,作为多靶点定向配体用于AD治疗。体外研究表明,某些分子对磷酸二酯酶4D(PDE4D)具有显着的抑制活性,强大的细胞内抗氧化能力,对金属诱导的Aβ聚集的有效抑制作用以及潜在的血脑屏障通透性。化合物7a中展示了在认知和空间记忆显著改善在Aβ 25-35在莫里斯水迷宫测试(MWM)-induce小鼠模型。这些结果表明化合物7a 是一个有前途的多功能候选人,值得进一步研究。
