Substitution on the Phe3 Aromatic Ring in Cyclic δ Opioid Receptor-Selective Dermorphin/Deltorphin Tetrapeptide Analogues: Electronic and Lipophilic Requirements for Receptor Affinity

Article abstract of DOI:10.1021/jm00087a006

In an effort to explore structural features affecting receptor recognition in a series of conformationally restricted tetrapeptides related to the cyclic, δ opioid receptor-selective analogue, , electronic, lipophilic, and steric effects at the P
