Zusammenfassung

Aspartof a programme to develop fluorescence-based methods for the study of the interactions between G-protein coupled receptors (GPCRs) and their ligands the preparation of low molecular weight fluorescence-labelled neuropeptide Y (NPY)Y-5 antagonists is reported. The naphthylsulfonyl group in the potent quinazoline-type NPYY5 receptor antagonist CGP 71683A was replaced with a dansyl, ...
