  • PubMed Abstract: 

    Pleiotropic intervention may be a requirement for effective limitation of the progression of multifactorial diseases such as Alzheimer's Disease. One approach to such intervention is to design a single chemical entity capable of acting on two or more targets of interest, which are accordingly known as Multi-Target Directed Ligands (MTDLs). We recently described donecopride, the first MTDL able to simultaneously inhibit acetylcholinesterase and act as an agonist of the 5-HT 4 receptor, which displays promising activities in vivo. Pharmacomodulation of donecopride allowed us to develop a novel series of indole derivatives possessing interesting in vitro activities toward AChE and the σ 1 receptor. The crystal structures of complexes of the most promising compounds with Torpedo californica AChE were solved in order to further understand their mode of inhibition.
