scyllo-inositol derivatives have been synthesized which contain deoxy, fluoro, chloro, and methoxy substitutions. The effects of these compounds on the aggregation cascade of Abeta42 have been investigated using electron microscopy (EM). EM analyses revealed that the 1-deoxy-1-fluoro- and 1,4-dimethyl-scyllo-inositols significantly inhibit the formation of Abeta42 fibers. The other derivatives showed some alterations
scyllo-肌醇通过与淀粉样蛋白β(Abeta)肽直接相互作用抑制Abeta42纤维形成,已显示出有望作为阿尔茨海默氏病的潜在治疗剂。为了探索肌醇-Abeta42相互作用的分子细节,已合成了一系列含有脱氧,氟,氯和甲氧基取代的鞘氨醇衍生物。这些化合物对Abeta42的聚集级联反应的影响已使用电子显微镜(EM)进行了研究。EM分析表明,1-脱氧-1-氟-和1,4-二甲基-scyllo-肌醇显着抑制Abeta42纤维的形成。其他衍生物在生产的Abeta42纤维的形态上显示出一些变化。
