Abstract

3,3′,4,4′-Tetrahydroxybiphenyl and three isomeric 3,3″,4,4″-tetrahydroxyterphenyls with varying geometries around the central phenyl ring have been synthesized and evaluated for their in vitro activity against aggregation of Alzheimer’s amyloid-β peptide (Aβ). Results from Congo red spectral-shift assays reveal that all four compounds successfully inhibit association of Aβ monomers. For the tetrahydroxyterphenyls, efficacy varies with linker geometry: the ortho-arrangement affords the most successful inhibition and the para-geometry the least, perhaps due to differing abilities of these compounds to bind Aβ. Of the four small molecules studied, 3,3′,4,4′-tetrahydroxybiphenyl is the most effective inhibitor, reducing Aβ aggregation by 50% when present in stoichiometric concentrations.
