a Schematic representation of the allosteric agonist PCO371 bound to PTH1R (PDB: 8GW8). b Detailed binding modes of PTH1R binding to PCO371. Hydrogen bonds are presented as orange dashes. c Superposition of the PTH1R bound to PCO371 (displayed in pink) and PTH (displayed in blue) reveals conformational changes upon PCO371 binding
