  Structure−Activity Relationship of Imidazo[1,2-a]pyridines as Ligands for Detecting β-Amyloid Plaques in the Brain

  摘要：

  A series of novel beta-amyloid (Abeta) aggregate-specific ligands, 2-(4'-dimethylaminophenyl)-6-iodoimidazo[1,2-alpha]pyridine, (IMPY), and its related derivatives were prepared. An in vitro binding study with preformed Abeta aggregates showed that 16(IMPY) and its bromo derivative competed with binding of 2-(4'-dimethylaminophenyl)-6-iodobenzothiazole, [I-125]7(TZDM), a known ligand for Abeta aggregates, with high binding affinities (K-i = 15 and 10 nM, respectively). In vitro autoradiography of brain sections of a transgenic mouse (Tg2576) with [I-125]16(IMPY) displayed high selective binding to amyloid-like structures, comparable to that observed by staining with thioflavin-S visualized under fluorescence. In vivo biodistribution after an intravenous injection of [I-125]16(IMPY) in normal mice showed a high initial brain uptake and fast washout, indicating a low background activity associated with this iodinated ligand. Taken together, the data suggests that [I-123]16(IMPY) may be useful for imaging Abeta aggregates in patients with Alzheimer's disease.

• Synthesis and biological evaluation of imidazo[1,2-a]pyrimidines and imidazo[1,2-a]pyridines as new inhibitors of the Wnt/β-catenin signaling

  Wnt/β-catenin signaling plays an important role in the regulation of embryonic development and tumorigenesis. Since its deregulation results in severe human diseases, especially cancer, the Wnt signaling pathway constitutes a promising platform for pharmacological targeting of cancer. In this study we synthesized a series of imidazo[1,2-a]pyrimidines and imidazo[1,2-a]pyridines and identified some derivatives that were able to inhibit the Wnt/β-catenin signaling pathway in a luciferase reporter assay and cell proliferation in selected cancer cell lines, endowed with APC or β-catenin gene mutations. The most active compounds significantly downregulate the expression of Wnt target genes such as c-myc and cyclin D1. Further studies indicated that these compounds function independently of GSK-3β activity. More importantly, in vivo experiments, carried out on a Wnt-reporter zebrafish model indicate, in particular for compounds 4c and 4i as the most active compounds, an activity comparable to that of the reference compound IWR1, suggesting their potential use not only as small molecule inhibitors of the Wnt/β-catenin signal in Wnt driven cancers, but also in other Wnt-related diseases.
