A novel synthetic strategy forin situcyclisation of peptides and conjugation with functional boron dipyrromethenes (BODIPYs) has been developed. Linear peptides with up to 16 amino acid residues can be cyclised effectively and the resulting conjugates can be isolated in higher than 20% yield. One of the conjugates having a cyclic RGD moiety has been studied bothin vitroandin vivo. It exhibits high and selective affinity towards the αvβ3-positive cell lines and induces high photocytotoxicity. The conjugate can also selectively localise in and effectively inhibit the growth of αvβ3-overexpressed tumourin vivo.
