A highly systematic approach for the development of both orally bioavailable and bioactive cyclic N‐methylated hexapeptides as high affinity ligands for the integrin αvβ3 is based on two concepts: a) screening of systematically designed libraries with spatial diversity and b) masking of the peptide charge with a lipophilic protecting group. The key steps of the method are 1) initial design of a combinatorial library of N‐methylated analogues of the stem peptide cyclo(d‐Ala‐Ala5); 2) selection of cyclic peptides with the highest intestinal permeability; 3) design of sublibraries with the bioactive RGD sequence in all possible positions; 4) selection of the best ligands for RGD‐recognizing integrin subtypes; 5) fine‐tuning of the affinity and selectivity by additional Ala to Xaa substitutions; 6) protection of the charged functional groups according to the prodrug concept to regain intestinal and oral permeability; 7) proof of biological effects in mice after oral administration.
