Discovery of a novel multifunctional carbazole–aminoquinoline dimer for Alzheimer's disease: copper selective chelation, anti-amyloid aggregation, and neuroprotection

A novel multifunctional carbazole–aminoquinoline dimer PZ001 was designed, synthesized, and evaluated. The results indicated that PZ001 possessed selective copper chelation, and inhibited copper-induced Aβ1–42 aggregation. Furthermore, PZ001 exerted powerful neuroprotection against glutamate-induced HT22 cell death. These results suggest that PZ001 may be a promising multifunctional anti-AD compound.
