Transport substrates and modulators of the human multidrug resistance (MDRI) P- glycoprotein (Pgp) are generally lipophilic cationic compounds, many with substituted aryl moieties. We sought to synthesize aromatic technetium-isonitrile complexes to enable functional detection in vivo of Pgp expression in tissues. A series of substituted aromatic isonitrile analogs were synthesized from their corresponding amines by reaction with ...
