The nociceptin/orphanin FQ peptide receptor (NOP) couples to G proteins and β-arrestins, but how the peptide address domain influences transducer preference remains unclear. We synthesized ninety N/OFQ(1−13)-NH2 analogues with acylated lysine-based or related non-natural residues at positions 5−13 and evaluated NOP−G...

This work extends FAST to AFE calculations with and without enhanced sampling of a particular degree of freedom of interest (FAST/MBAR) and shows that enhanced sampling significantly increases the mobility of the targeted degree of freedom at the cost of reduced sampling efficiency over λ space.

The model showing higher stability in molecular dynamics simulations and consistency with known structure–activity relationships served as template to design novel hNPS analogues, which revealed the model's inability to capture hNPS bioactive conformation, as most analogues were inactive as agonists.
