based on the scaffold of ML10302, a highly specific and partial 5-HT4R agonist, were efficiently prepared by parallel supported synthesis and their binding affinities and agonist activities evaluated. Furthermore, we showed that, in vivo, the two best candidates exhibited neuroprotective activity by increasing the level of the soluble form of the amyloid precursor protein (sAPPα) in the cortex and hippocampus
5-羟色胺5-HT 4受体(5-HT 4 R)激动剂特别适合治疗阿尔茨海默氏病,因为它们具有缓解认知缺陷和调节淀粉样β蛋白(Aβ)产生的能力。然而,尽管迄今为止合成了范围广泛的5-HT 4 R激动剂,但仍然缺乏有效的和选择性的5-HT 4 R激动剂。在本研究中,基于ML10302支架的分子的两个文库,即高度特异性和部分5-HT 4R激动剂可通过平行支持的合成方法有效制备,并评估其结合亲和力和激动剂活性。此外,我们表明,在体内,通过增加小鼠皮质和海马中淀粉样前体蛋白(sAPPα)的可溶形式的水平,两个最佳候选物表现出神经保护活性。有趣的是,这些化合物中的一种还可以在体外抑制Aβ原纤维的形成。
