Selective targeting of anticancer drugs to the tumor site is critical for effective cancer therapy. The cell adhesion molecule integrin α v β 3 is not readily detectable in quiescent vessels but highly expressed in angiogenic vessels and tumor cells. [ 1 ] This restricted expression profi le and good accessibility of integrin α v β 3 make it an ideal target for drug delivery purposes. [ 2 ] A number of synthetic cyclized arginine–glycine–aspartic acid sequences (RGDs) containing peptides, such as RGDyK, RGDfK, RGDfV, and RGDyV, have been identifi ed to have high affi nity with integrin α v β 3 . There has been growing interest in the synthesis and utilization of polymer–RGD conjugates for drug delivery, [ 3 ] gene delivery, [ 4 ] and imaging applications. [ 5 ]
