Adenine-derived scaffolds enabled selective adenosine receptor antagonists; tryptophan modifications led to somatostatin receptor ligands.  The molecule, not the receptor, becomes the guiding principle. Does it interact with the receptor in a way that biology can use? Core message: The receptor is only half the story. The molecule is the other half.

reflects the cellular background of the expression system, not the tissue or disease context in which the receptor This gap becomes consequential when translational interpretation depends on receptor behavior in environments where protein expression levels, membrane composition, and accessory protein availability differ substantially In these systems, receptor pharmacology can be examined alongside disease-relevant phenotypic responses This review describes the history, structure, and GPCR-dependent and independent functions of both protein
