摘要
Amyloid formation plays a major role in a number of neurodegenerative diseases, including Alzheimer's disease. Amyloid-beta peptides (A beta) are one of the primary markers associated with this pathology. A beta aggregates exhibit a diverse range of morphologies with distinct pathological activities. Recognition of the A beta aggregates by using small molecule-based probes and sensors should not only enhance understanding of the underlying mechanisms of amyloid formation, but also facilitate the development of therapeutic strategies to interfere with amyloid neurotoxicity. BODIPY (boron dipyrrin) dyes are among the most versatile small molecule fluorophores. BODIPY scaffolds could be functionalized to tune their photophysical properties to the desired ranges as well as to adapt these dyes to various types of conditions and environments. Thus, BODIPY dyes could be viewed as unique platforms for the design of probes and sensors that are capable of detecting and tracking structural changes of various A beta aggregates. This review summarizes currently available examples of BODIPY dyes that have been used to investigate conformational changes of A beta peptides, self-assembly processes of A beta, as well as A beta interactions with various molecules.
