Abstract
Eight cinnamic acid derivatives were studied as prion inhibitors in vitro and their cytotoxicity was evaluated. Ferulic (3-methoxy-4-hydroxycinnamic) acid, 3,4,5-trimethoxycin- namic acid and methyl 3-ethoxy-4-acetamidoxycinnamate were found to inhibit amyloid fibril formation, seeding, and spontaneous aggregation of recombinant ovine prion protein. None of the compounds demonstrated cytotoxicity on human neuroblastoma SH-SY5Y cells.
