Synthesis and characterization of a macrocyclic near-infrared optical scaffold

J Am Chem Soc. 2003 Jul 2;125(26):7766-7. doi: 10.1021/ja034186o.

Abstract

Macrocyclization of a bioactive peptide with a bifunctional near-infrared fluorescent optical probe gives a compound that retained the receptor binding affinity of the peptide and the photophysical properties of the optical probe. The robust nature of the new compound provides a structural framework for optimizing the activity of bioactive molecules and for monitoring chemical or biological processes in vivo and in vitro by near-infrared optical methods.
