Recently, the tryptophan-containing
noncationizable opioid peptides
emerged with atypical structure and unexpected in vivo activity. Herein, we describe analogs of the naturally occurring mixed κ/μ-ligand
c[Phe-d-Pro-Phe-Trp] 1 (CJ-15,208). Receptor
affinity, selectivity, and agonism/antagonism varied upon enlarging
macrocycle size, giving the μ-agonist 9 or the
δ-antagonist 10 characterized by low nanomolar
affinity. In particular, the μ-agonist c[β-Ala-d-Pro-Phe-Trp] 9 was shown to elicit potent antinociception
in a mouse model of visceral pain upon systemic administration.
