2018 Peptides  
These chimeric molecules consist of YGGF sequence, a crucial motif in the N-terminus of natural opioid peptides, and Ac-RYYRIK-NH2, which was isolated from a combinatorial peptide library as an antagonist  ...  The designed chimeric peptide ligands presented in this study accommodate well into a group of multitarget opioid compounds that include opioid-non-opioid peptide dimer analogues, dual non-peptide dimers  ...  Hybrid or bifunctional peptide or non-peptide ligands developed recently, bearing two pharmacophores, represent novel biochemical tools in investigating GPCRs and their interacting complexes.  ...
