Spermine conjugates 2–6, carrying variously decorated 3,5-dibenzylidenepiperidin-4-one as bioactive motives, were designed to direct antiaggregating properties into mitochondria, using a polyamine functionality as the vehicle tool. The study confirmed mitochondrial import of the catechol derivative 2, which displayed effective antiaggregating activity and neuroprotective effects against Aβ-induced toxicity. Notably, a key functional role for the polyamine motif in Aβ molecular recognition was also unraveled. This experimental readout, which was supported by in silico studies, gives important new insight into the polyamine’s action. Hence, we propose polyamine conjugation as a promising strategy for the development of neuroprotectant leads that may contribute to decipher the complex picture of Aβ toxicity.
