Triple molecular target approach to selective melanoma cytotoxicity.

Phenylalanine-linked pyrrolo[1,2-a]benzimidazoles were successfully designed to target melanoma cells in vitro. Our design utilised three molecular targets: a phenylalanine pump, the reducing enzyme DT-diaphorase, and IMP dehydrogenase. We describe the synthesis of these compounds as well as the results of in vitro, in vivo, and QSAR studies.
