Considerable evidence had been accumulated for the existence of multiple opioid receptor subtypes prior to the cloning of the cDNAs encoding the three major opioid receptor types-the mu, delta, and kappa opioid receptors [1,2]. Since our laboratory was working on the development of selective delta receptor agonists, including [D-Pen2, D-Pen4] enkephalin (DPDPE) and its halogenated analogues, we were primarily interested in the characterization of the delta opioid receptor and the identification of putative delta opioid receptor subtypes.
