To search for more efficient anti-Alzheimer agents, a series of novel sarsasapogenin-triazolyl hybrids were designed, synthesized, and evaluated for their Aβ1−42 aggregation inhibitory activities. Most of these new hybrids displayed potent Aβ1−42 aggregation inhibition. In particular, the promising compounds 6j and 6o displayed a better ability to interrupt the formation of Aβ1−42 fibrils than curcumin
Sarsasapogenin是知母中的活性成分,是治疗阿尔茨海默氏病的有前途的生物活性先导化合物。要搜索更有效的抗阿尔茨海默病药,一系列新萨洒三唑基杂种的设计,合成,并评价它们的A β 1-42聚集抑制活性。大多数这些新杂交种显示有效的一个β 1-42聚集抑制。特别地,所述有前途的化合物6J和60所显示的更好的能力以中断的形成β 1-42比姜黄素原纤维。此外,6j和6o在SH-SY5Y细胞中对H 2 O 2诱导的神经毒性具有中等程度的神经保护作用。为了调查是否6J和60可以改善认知缺陷,我们进行行为学测试,以检查由A脑室注射引起的学习和记忆能力β 1-42(ICV-A β 1-42)在小鼠和TUNEL染色观察神经细胞凋亡在海马中。获得的结果表明,口服6j和6o治疗可显着改善行为测试和TUNEL染色的认知障碍,显示6j和6o减轻大脑中神经元的损失。综上所述,我们获得的结果表明,sarsasa
