  • 2,5-Diketopiperazine, also known as piperazine-2,5-dione and as the cyclodipeptide cyclo(Gly-Gly), is an organic compound and the smallest cyclic dipeptide that consists of a six-membered ring containing two amide linkages where the two nitrogen atoms and the two carbonyls are at opposite positions in the ring. (wikipedia.org)
  • These cyclic dipeptides incorporate both donor and acceptor groups for hydrogen bonding and are small, conformationally constrained heterocyclic scaffolds in which diversity can be introduced at up to six positions and stereochemistry controlled at up to four positions, and they are stable to proteolysis.
