Thus, they can cross the blood-brain-barrier (BBB) and bind to β-amyloid plaques after administration into the body, making them useful for treatment, prevention, or imaging of Alzheimer's disease.
公开了公式1的苯甲醛苯胺衍生物,其中R1-R5分别选自氢、C1-C4烷基和F(它们中至少有一个是F),每个R6-R10分别选自氢、C1-C4烷基、OH、OCH3、NH2、NHCH3和N(CH3)2(它们中至少有一个是OH、OCH3、NH2、NHCH3或N(CH3)2)。根据本发明的苯甲醛苯胺衍生物具有高亲和力β-淀粉样斑块。因此,它们可以穿过血脑屏障(BBB),在体内给药后结合β-淀粉样斑块,使其用于治疗、预防或成像阿尔茨海默病。
