A structure-activity relationship study and combinatorial synthetic approach of C-terminal modified bifunctional peptides that are delta/mu opioid receptor agonists and neurokinin 1 receptor antagonists.[Pubmed:18266313]

J Med Chem. 2008 Mar 13;51(5):1369-76.

A series of bifunctional peptides with opioid agonist and substance P antagonist bioactivities were designed with the concept of overlapping pharmacophores. In this concept, the bifunctional peptides were expected to interact with each receptor separately in the spinal dorsal horn where both the opioid receptors and the NK1 receptors were found to be expressed, to show an enhanced analgesic effect, no opioid-induced tolerance, and to provide better compliance than coadministration of two drugs. Compounds were synthesized using a two-step combinatorial method for C-terminal modification. In the method, the protected C-terminal-free carboxyl peptide, Boc-Tyr( tBu)- d-Ala-Gly Phe-Pro-Leu-Trp(Boc)-OH, was synthesized as a shared intermediate using Fmoc solid phase chemistry on a 2-chlorotrityl resin. This intermediate was esterified or amidated in solution phase. The structure-activity relationships (SAR) showed that the C-terminus acted as not only a critical pharmacophore for the substance P antagonist activities, but as an address region for the opioid agonist pharmacophore that is structurally distant from the C-terminal. Among the peptides, H-Tyr- d -Ala-Gly-Phe-Pro-Leu-Trp-NH-Bzl ( 3) demonstrated high binding affinities at both delta and mu receptors ( K i = 10 and 0.65 nM, respectively) with efficient agonist functional activity in the mouse isolated vas deferens (MVD) and guinea pig isolated ileum (GPI) assays (IC 50 = 50 and 13 nM, respectively). Compound 3 also showed a good antagonist activity in the GPI assay with substance P stimulation ( K e = 26 nM) and good affinity for the hNK1 receptor ( K i = 14 nM). Consequently, compound 3 is expected to be a promising and novel type of analgesic with bifunctional activities.

Effect of aromatic amino acid substitutions in the 3-position of cyclic beta-casomorphin analogues on mu-opioid agonist/delta-opioid antagonist properties.[Pubmed:8956074]

Int J Pept Protein Res. 1996 Nov;48(5):411-9.

The beta-casomorphin-5 analog H-Tyr-c[-D-Orn-2-Nal-D-Pro-Gly-] (2-Nal = 2-naphthylalanine) was the first reported cyclic opioid peptide with mixed mu agonist/delta antagonist properties [R. Schmidt et al. (1994) J. Med. Chem. 37, 1136-1144]. The 2-Nal3 residue in this peptide was replaced with benzothienylalanine (Bta) (3), His(Bzl) (4), Tyr(Bzl) (5), 4'-benzoylphenylalanine (Bpa) (6), 4'-benzylphenylalanine (Bzp) (7), thyronine (Thy) (8), thyroxine (Thx) (9), 4'-biphenylalanine (Bip) (10), 4'-biphenylglycine (Bpg) (12) and 3,3-diphenylalanine (Dip) (14), and the in vitro opioid activity profiles of the resulting compounds were determined in mu and delta receptor-representative binding assays and bioassays. Analogues 3, 12 and 14 were full agonists in the mu receptor-representative guinea-pig ileum (GPI) assay and also were agonists in the delta receptor-representative mouse vas deferens (MVD) assay. The agonist effects of the latter compounds in the MVD assay were antagonized by the highly selective delta antagonist H-Tyr-Tic-Phe-Phe-OH (TIPP), indicating that they were triggered by delta receptor activation. The Bzp3- and Bip3- containing peptides 7 and 10 turned out to be mu antagonists against the mu selective agonist H-Tyr-D-Ala-Phe-Phe-NH2 in the GPI assay. The other analogues were weak partial mu agonists which displayed remarkably decreased mu receptor affinity as compared to parent peptide 1. Compounds 4-10 were found to be delta antagonists in the MVD assay. Analogues 4 and 9 exhibited delta antagonist potency similar to that of parent peptide 1, while compounds 5-8 and 10 showed 3-12-fold higher delta antagonist potency against DPDPE and deltorphin I and, in most cases, increased delta receptor affinity. These results indicate that the delta receptor tolerates bulky aromatic side chains in the 3-position of cyclic beta-casomorphin analogs with either delta agonist or delta antagonist properties. However, these compounds displayed drastically reduced mu receptor affinity in nearly all cases.
