✦ Synopsis

MiZd treatment of sepiomeZanin and biosynthetic ewneZanins with NaBH4 in 0.1 N NaOH leads to the isolation of 5,6-dihydroxyindoZe-2-carboxylic acid (21, a component of structural interest which may account for most of the degradation products of metanins so far obtained.

Mammalian melanins exist in two chemically disnylalanine (dopa), 3 which is produced from tyrosine tinct forms: the brown to black eumelanins and the by the action of tyrosinase. Dopaquinone undergoes yellow to reddish pheomelanins. Eumelanins are dea series of redox reactions leading to eumelanin f
