Naphthalene Dicarboxaldehyde as an Electrophilic Fluorogenic Moiety for Affinity Labeling: Application to Opioid Receptor Affinity Labels with Greatly Improved Fluorogenic Properties

Year: 2002

Type: article

Abstract: To develop ligands with fluorogenic properties amenable for following the kinetics of cross-linking to receptors, a naphthalene dicarboxaldehyde moiety has been attached to an opiate pharmacophore 2 and evaluated in mu-opioid receptors. The fluorescence of the benzo[f]isoindole formed upon cross-linking of mu-opioid receptors by 2 permitted the time-course of covalent bonding to be followed. This demonstrated proof-of-concept suggests the usefulness of naphthalene dicarboxaldehyde-containing affinity labels as kinetic probes.
