Cyclic arginine-glycine-aspartic (RGD) peptides that specifically bind to integrin ανβ3 have been developed for drug delivery, tracers, and imaging for tumor diagnosis and treatment. Herein, a series of polycyclic RGD peptides containing dual, tri, and tetra rings were designed and synthesized through sortase A-mediated ligation. An in vitro test on cell adhesion inhibition indicated that the RGD peptide containing tricylic structure exhibited outstanding potency and selectivity for ανβ3 integrin.Targeted delivery of drugs into specific c
