Multicomponent, fragment-based synthesis of polyphenol-containing peptidomimetics and their inhibiting activity on beta-amyloid oligomerization
Organic & Biomolecular Chemistry(2017)
摘要
A new and short fragment-based approach towards artificial (but "natural-based") complex polyphenols has been developed, exploiting the Ugi multicomponent reaction of phenol-containing simple substrates. The resulting library of compounds has been tested for its capacity to inhibit beta-amyloid protein aggregation, as a possible strategy to develop new chemical entities to be used as prevention or therapy for Alzheimer's disease. Some of the members of this library have demonstrated, in thioflavin assays, a highly promising activity in inhibiting aggregation for two beta-amyloid peptides: A beta 1-42 and the truncated A beta pE3-42.
