Synthesis and muscarinic acetylcholine receptor (mAChR) antagonist activity of substituted piperazine-triazoles

This study describes synthesis of a series of piperazine-triazole derivatives and their ex vivo evaluation for preliminary muscarinic acetylcholine receptor (mAChR) blocking activity on rat ileum model. A molecule based on benzonitrile piperazine triazole scaffold showed good tissue relaxation and blocking of neurotransmitter ACh in the ex vivo experiment.
