The present invention is directed to substituted imidazo[1,2-a]pyridine derivatives, pharmaceutically acceptable salts thereof, and tautomers of such compounds or salts, that inhibit β-site amyloid precursor protein-cleaving enzyme (BACE) and that may be useful in the treatment of diseases in which BACE is involved, such as Alzheimer's disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which BACE is involved.

displayed similar bands at λmax 308 nm in UV-vis spectra. The peaks shift to λmax 350 nm and λmax 341 nm after deprotonation. C1 itself exhibits the aggregation induced emission (AIE) phenomenon in water–DMSO (1 : 1). This is the first report of an imidazopyridine moiety being involved in a solvent-switched AIE effect via S⋯Oconformational locking. UV-vis and fluorescence spectra of the compounds were
已经开发出方便且直接的方法,用于通过两种新型咪唑并吡啶基甲酰胺(C1和C2)在有机和水介质中检测和定量评估氟阴离子。合成的分子通过“开启”荧光模式对识别氟离子表现出高选择性和增强的灵敏度。氟离子驱动的 N-H 质子去质子化和随后的光谱变化已通过1 H 和19 F NMR 光谱技术进行了表征。单晶 XRD 阐明了添加氟阴离子后去质子化的结构证据,其中C1.S ( C1 - .2H 2生成 O.TBA + ) 和C2.S ( C2 - .2H 2 O.TBA + ) 盐。因此,C1在λ max 340 nm 处显示出宽吸收带,而C2在 UV-vis 光谱中在λ max 308 nm 处显示出类似的吸收带。去质子化后,峰移至λ max 350 nm 和λ max 341 nm。C1本身在水-DMSO (1:1) 中表现出聚集诱导发射 (AIE) 现象。这是关于咪唑并吡啶部分参与溶剂转换 AIE 效应的首次报道S⋯O
