Systematic in Vivo Screening of a Series of 1-Propyl-4-arylpiperidines against Dopaminergic and Serotonergic Properties in Rat Brain: A Scaffold-Jumping Approach
A series of 1-propyl-4-arylpiperidines were synthesized and their effects on the dopaminergic and serotonergic systems tested in vivo and in vitro. Scaffold jumping among five- and six-membered bicyclic aryl rings attached to the piperidine ring had a marked impact on these effects. Potent and selective dopamine D2 receptor antagonists were generated from 3-indoles, 3-benzoisoxazoles, 3-benzimidazol-2-one
