Dopachrome o-semiquinone

[(2R)-2-carboxy-6-hydroxy-2,3-dihydro-1H-indol-5-yl]oxidanyl

C9H8NO4 (194.0453)


Dopachrome o-semiquinone is the semiquinone derivative of dopachrome. The non-decarboxylative tautomerization of L-dopachrome into 5,6-dihydroxyindole-2-carboxylic acid in the melanin biosynthetic pathway is catalyzed by tyrosinase-related protein-2, a melanocyte-specific enzyme. dopachrome o-semiquinone is the semiquinone derivative of dopachrome.
