A small set of 5-HT3 receptor ligands has been evaluated with regard to their potential AChE inhibitory activity with the aim of discovering new compounds interfering with acetylcholine release and degradation. The inhibitory activity has been theoretically rationalized in terms of the interaction with an AChE crystallographic model. Compounds 2 and 3 inhibited the enzyme at a concentration lower than 1.5 μM, while 6 established an interaction energy with AChE comparable to tacrine, but with insufficient conformational reorganization.

Abstract
A small set of 5-HT3 receptor ligands has been evaluated with regard to their potential AChE inhibitory activity with the aim of discovering new compounds interfering with acetylcholine release and degradation. The inhibitory activity has been theoretically rationalized in terms of the interaction with an AChE crystallographic model. Compounds 2 and 3 inhibited the enzyme at a concentration lower than 1.5 μM, while 6 established an interaction energy with AChE comparable to tacrine, but with insufficient conformational reorganization.File in questo prodotto:
