G protein‐coupled receptors (GPCRs) represent an important group of membrane proteins that play a central role in modern medicine. Unfortunately, conformational promiscuity hampers full therapeutic exploitation of GPCRs, since the largest population of the receptor will adopt a basal conformation, which subsequently challenges screens for agonist drug discovery programs. Herein, we describe a set of peptidomimetics able to mimic the ability of G proteins in stabilizing the active state of the β2 adrenergic receptor (β2AR) and the dopamine 1 receptor (D1R). During fragment‐based screening efforts, these (un)constrained peptide analogues of the α5 helix in Gs proteins, were able to identify agonism pre‐imprinted fragments for the examined GPCRs, and as such, they behave as a generic tool, enabling an engagement in agonist earmarked discovery programs.
