Phenolic melanin precursors can be utilized for the development of anti-melanoma agents. The sulphur homologue of tyrosine, 4-S-cysteinylphenol (CP) and its decarboxylation product, 4-S-cysteaminylphenol (CAP) were shown to be substrates of melanoma tyrosinase, forming melanin-like pigment. Both, bu

This study reports the synthesis of "C-labelled N-acetyl-4-S-cysteaminylphenol (['4C]N-Ac-4-S-CAP), a potent melanocytotoxic and anti-melanoma agent. A reaction of [U-'4C]phenol with NH2CHZCH2S+ cation in HBr solution was used for the synthesis of (4-S-cysteaminyl['4C]pheno1['4C]4-S-CAP). The excess
