Abstract This paper reports a detailed conformational characterization in solution by 1H-NMR in H2O and DMSO-d6 and molecular modeling simulations of cyclic peptides containing the RGDDV pharmacophore and the RGDY(Me)R pharmacophore. These two pentapeptide sequences when properly constrained in cyclic peptides are low to sub-nanomolar inhibitors of integrin alpha(v)beta3. The peptides containing the RGDDY(Me)R sequence bind potently to integrin alphaIIb3 as well. The conformations found in H2O and in DMSO-d6 solutions are valuable for the design of peptidomimetics of these two pharmacophores. The structure-activity relationships of the RGDDV and RGDY(Me)R pharmacophores within cyclic peptides are discussed. Specifically, the orientation of surface-accessible chemical features on the ligand, such as hydrophobic, positive and negative ionizable groups, which are considered to be responsible for the desired biological activity, is focused on.
