Abstract
![]()
The nociceptin/orphanin FQ (N/OFQ)/N/OFQ receptor (NOP) system
controls different biological functions including pain and cough reflex.
Mixed NOP/opioid receptor agonists elicit similar effects to strong
opioids but with reduced side effects. In this work, 31 peptides with
the general sequence [Tyr/Dmt1,Xaa5]N/OFQ(1-13)-NH2 were synthesized and pharmacologically characterized for
their action at human recombinant NOP/opioid receptors. The best results
in terms of NOP versus mu opioid receptor potency were obtained by
substituting both Tyr1 and Thr5 at the N-terminal
portion of N/OFQ(1-13)-NH2 with the noncanonical amino
acid Dmt. [Dmt1,5]N/OFQ(1-13)-NH2 has been identified
as the most potent dual NOP/mu receptor peptide agonist so far described.
Experimental data have been complemented by in silico studies to shed light on the molecular mechanisms by which the peptide
binds the active form of the mu receptor. Finally, the compound exerted
antitussive effects in an in vivo model of cough.

Abstract
INTRODUCTION Molecular docking has been consolidated as one of the most important methods in the molecular modeling field. It has been recognized as a prominent tool in the study of protein-ligand complexes, to describe intermolecular interactions, to accurately predict poses of multiple ligands, to discover novel promising bioactive compounds. Molecular docking methods have evolved in terms of their accuracy and reliability; but there are pending issues to solve for improving the connection between the docking results and the experimental evidence. AREAS COVERED In this article, the author reviews very recent innovative molecular docking applications with special emphasis on reverse docking, treatment of protein flexibility, the use of experimental data to guide the selection of docking poses, the application of Quantum mechanics(QM) in docking, and covalent docking. EXPERT OPINION There are several issues being worked on in recent years that will lead to important breakthroughs in molecular docking methods in the near future These developments are related to more efficient exploration of large datasets and receptor conformations, advances in electronic description, and the use of structural information for guiding the selection of results.

Ribeiro JML, Filizola M. Insights From Molecular Dynamics Simulations of a Number of G-Protein Coupled Receptor Targets for the Treatment of Pain and Opioid Use Disorders. Front Mol Neurosci 2019; 12:207.

Abstract
Effective treatments for pain management remain elusive due to the dangerous side-effects of current gold-standard opioid analgesics, including the respiratory depression that has led to skyrocketing death rates from opioid overdoses over the past decade. In an attempt to address the horrific opioid crisis worldwide, the National Institute on Drug Abuse has recently proposed boosting research on specific pharmacological mechanisms mediated by a number of G protein-coupled receptors (GPCRs). This research is expected to expedite the discovery of medications for opioid overdose and opioid use disorders, leading toward a safer and more effective treatment of pain. Here, we review mechanistic insights from recent all-atom molecular dynamics simulations of a specific subset of GPCRs for which high-resolution experimental structures are available, including opioid, cannabinoid, orexin, metabotropic glutamate, and dopamine receptor subtypes.
