A Palette of Fluorescent Thiophene-Based Ligands for the Identification of Protein Aggregates

Chemistry. 2015 Oct 19;21(43):15133-7. doi: 10.1002/chem.201502999. Epub 2015 Sep 21.

Abstract

By replacing the central thiophene unit of an anionic pentameric oligothiophene with other heterocyclic moities, a palette of pentameric thiophene-based ligands with distinct fluorescent properties were synthesized. All ligands displayed superior selectivity towards recombinant amyloid fibrils as well as disease-associated protein aggregates in tissue sections.

Keywords: Alzheimer’s disease; fluorescent probes; luminescence; microscopy; oligothiophenes.
