Abstract

There can be little doubt that the basis of the recent remarkable advances in our understanding of the physiological and pathophysiological roles of 5-HT has been the identification and development of compounds with selectivity for 5-HT receptor subtypes [1–4]. Among these, none has been more spectacular nor of potentially greater therapeutic significance than the advent of ligands with potency and selectivity for the 5-HT3 receptor subtype. The purpose of this article is to describe these compounds and their use as tools to identify 5-HT3 receptors and their properties. Both selective agonists and antagonists will be considered as well as a number of their radiolabeled counterparts. The historical development of these compounds will not be dealt with since it has been the subject of recent comprehensive review [5–8].
