Notably, 6-chloro-1,2,3,4-tetrahydroacridine 10 showed an EC50 of 0.17 μM, which was lower than that displayed by reference compound BiCappa. More importantly, 10 possessed the capability to contrast prion fibril formation and oxidative stress, together with a low cytotoxicity. This study further corroborates the bivalent strategy as a viable approach to the rational design of anti-prion chemical probes.
