A quinoxaline scaffold exhibits various bioactivities in pharmacotherapeutic interests. In this research, twelve quinoxaline derivatives were synthesized and evaluated as new acetyl-cholinesterase inhibitors. We found all compounds showed potent inhibitory activity against acetyl-cholinesterase (AChE) with IC50 values of 0.077 to 50.080 μM, along with promising predicted drug-likeness and blood–brain barrier (BBB) permeation. In addition, potent butyrylcholinesterase (BChE) inhibitory activity with IC50 values of 14.91 to 60.95 μM was observed in some compounds. Enzyme kinetic study revealed the most potent compound (6c) as a mixed-type AChE inhibitor. No cytotoxicity from the quinoxaline derivatives was noticed in the human neuroblastoma cell line (SHSY5Y). In silico study suggested the compounds preferred the peripheral anionic site (PAS) to the catalytic anionic site (CAS), which was different from AChE inhibitors (tacrine and galanthamine). We had proposed the molecular design guided for quinoxaline derivatives targeting the PAS site. Therefore, the quinoxaline derivatives could offer the lead for the newly developed candidate as potential acetylcholinesterase inhibitors.

The quinoxaline core is considered a privileged scaffold as it is found in a variety of biologically relevant molecules. Here we report the synthesis of a quinoxalin-6-amine library, screening against a panel of cancer cell lines and a structure-activity

A series of 29 new quinoxalines was synthesized and evaluated in vitro against several parasites (Leishmania donovani, Trypanosoma brucei brucei, and Trichomonas vaginalis). Several of them displayed interesting activities, and particularly four quinoxaline amides showed in vitro antileishmanial properties (IC50 less than 20 μM).
