Two multitarget hybrids, derived from an aza-analogue of CGP37157, a mitochondrial Na /Ca exchanger antagonist, and lipoic acid were designed in order to combine in a single molecule the antioxidant and Nrf2 induction properties of lipoic acid and the neuroprotective activity of CGP37157. The hybrid derivatives showed Nrf2 induction and radical scavenging properties, leading to a good neuroprotective profile against oxidative stress, together with an interesting antineuroinflammatory activity. The results obtained show differences in activity depending on the configuration of the chiral center of LA.
为了将 lipoic acid 的抗氧化和 Nrf2 诱导特性以及 CGP37157 的神经保护活性结合在一个分子中,设计了两种源自线粒体 Na+/Ca2+ exchanger 拮抗剂 CGP37157 的氮杂类似物的多靶点杂合分子。这些杂合衍生物表现出 Nrf2 诱导和自由基清除特性,对氧化应激具有良好的神经保护作用,同时具有有趣的抗神经炎症活性。得到的结果表明,LA 手性中心的构型不同会导致活性的差异。
