5,6-Dihydroxyindole (5,6DHI) and 5,6-dihydroxyindole-2-carboxylic acid (5,6DHI2C) are ultimate precursors of the black melanin, eumelanin. These indolic metabolites and their O-methyl derivatives are excreted in urine of melanoma patients at high levels and of healthy persons at low levels. We descr
Several catecholamines have been converted to 5,6-diacetoxyindole derivatives by the use of mushroom tyrosinase as oxidant. Melanin1 is a biopolymer found throughout the animal and plant kingdoms. In animals, the black pigment eumelanin occurs in skin, hair, feathers, insect cuticles, malignant mel
