Naturally occurring cinnamic acid derivatives prevent amyloid transformation of alpha-synuclein.

In search of the compounds that interfere with amyloid transformation of alpha-synuclein, 9 natural and synthetic cinnamic acid derivatives were studied. They are structurally similar to a half of curcumin, which has pronounced anti-aggregatory and anti-amyloid effects. We have shown that some of these derivatives prevent ovine prion protein amyloidization.
