Cyclo(RGDyK) shows high affinity and selectivity for αVβ3 over αVβ5 and αIIbβ3. Cyclo(RGDyK)-conjugated micelles (TPM) facilitated the cell-specific uptake of DiI into B16-F10 cells and HUVECs via integrin-mediated endocytosis compared with Cyclo(RGDyK) -free micelles (NPM).
In vivo
In apoE−/− mice, Cyclo(RGDyK) (1 nmol, i.v.) inhibits the increase of αVβ3 integrin expression in the intima of the left stenotic carotid artery.
