Ferulic acid and benzothiazole dimer derivatives with high binding affinity to beta-amyloid fibrils.


PMID 17544669

Abstract

New ferulic acid and benzothiazole dimer derivatives were synthesized and evaluated by in vitro competition assay using [(125)I]TZDM for their specific binding affinities to Abeta fibrils. In particular, 4a showed the most excellent binding affinity (K(i)=0.53 nM), compared to PIB (K(i)=0.77 nM), for benzothiazole binding sites of Abeta(1-42) fibrils. This result suggests a possibility of a potential AD diagnostic probe for detection of Abeta fibrils.
