Synthesis and pharmacological properties of a series of antidopaminergic piperidyl benzamides

Abstract
The synthesis and pharmacological screening for anti-apomorphine, stomach emptying and local anaesthetic activities of some new piperidylbenzamides is described. One of these, N-(1′-benzyl-4′-piperidyl)-2-methoxy-4-amino-5-chlorobenzamide (clebopride) is more potent than metoclopramide in tests related to blockade of cerebral dopamine receptors.
