Although the mu opioid receptor is the primary target of marketed opioid analgesics, several studies suggest the advantageous effect of combinations of mu and delta opioids. The novel compound RWJ-394674 [N,N-diethyl-4-[(8-phenethyl-8-azabicyclo]3.2.1]oct-3-ylidene)-phenylmethyl]-benzamide]; bound with high affinity to the delta opioid receptor (0.2 nM) and with weaker affinity to the mu opioid receptor (72 nM). 5′-O-(3-[35S]-thio)triphosphate binding assay demonstrated its delta agonist…

It is proposed that in this experimental respiration model, the delta antagonists naltrindole and H-Tyr-Tic(psi)[CH2NH]Phe- Phe-OH behave like delta agonists with low but sufficient intrinsic activities to reverse alfentanil-induced hypercapnia in rats.

It is concluded that i.p. administration of [3H]SNC121 is consistent with the duration of SNC80 antinociception, and the rapid formation of a BW373U86-like metabolite may also account, in part, for its convulsant properties.
