Research of effective drugs against Alzheimer's disease (AD) is currently one of the most challenging topics in medicinal chemistry. Despite the documented detrimental effect of the disruption of copper ion homeostasis in AD, this potential pharmacological target has been weakly explored. The design of chelators as drug candidates for copper regulation in AD brain should meet critical coordination chemistry requirements, in addition to requested biological parameters (membrane crossing, activity, ...). Among the various possibili- [a]
