activities were also confirmed in vivo since the most promising derivative 2 exhibited a remarkable antihyperlipidemic and antioxidant effect. In conclusion, rational drug design accompanied by structure-activity relationship studies led to compounds combining improved antioxidant and antihyperlipidemic activity that may serve as multifunctional agents against atherosclerosis.
直接促进冠状动脉和周围动脉粥样硬化发展的因果风险因素包括活性氧和升高的低密度脂蛋白血浆水平。我们在此设计了新的强力角鲨烯合酶(SQS)抑制剂,该抑制剂可同时解决脂质过氧化引起的氧化应激。以先前开发的吗啉衍生物为起点,我们通过取代或修饰吗啉环进行了广泛的结构变化,旨在获得最佳的SQS-抗氧化剂药理作用。化合物2、3和7作为最有效的双功能类似物出现,分别显示出SQS抑制的IC 50值为0.014、0.16和0.51μM,并进一步显着降低了肝微粒体膜的脂质过氧化。由于最有希望的衍生物2表现出显着的降血脂和抗氧化作用,因此在体内也证实了上述活性。总之,合理的药物设计和结构活性关系研究导致了结合了改进的抗氧化剂和降血脂活性的化合物,这些化合物可作为抗动脉粥样硬化的多功能药物。
