A perfect fit: The nanomolar affinity of a diketopiperazine‐derived cyclic RGD‐peptidomimetic for the integrin αvβ3 receptor can be attributed to its high structural pre‐organization. The trans‐diketopiperazinescaffold induces an extended RGD disposition permitting all important interactions with the extracellular domain of the αvβ3 integrin.
