Oxidation of leukoaminochrome to dopaminochrome and polymerization of dopaminochrome to neuromelanin . The DA oxidation can occur spontaneously, is accelerated by transition metal ions (Mn2+ or Fe2+), or can be catalyzed by a number of different enzymes [HMDB] 2-Descarboxy-cyclo-dopa 2,3-dihydro-5,6-dihydroxyindole 5,6-dihydroxy-2,3-dihydroindole 5,6-dihydroxyindoline 5,6-Indolinediol 56DHInn indoline-5,6-diol leucoaminochrome C8H9NO2 151.1626 151.063328537 2,3-dihydro-1H-indole-5,6-diol 2,3-dihydro-1H-indole-5,6-diol 29539-03-5 OC1=C(O)C=C2NCCC2=C1 InChI=1S/C8H9NO2/c10-7-3-5-1-2-9-6(5)4-8(7)11/h3-4,9-11H,1-2H2 VGSVNUGKHOVSPK-UHFFFAOYSA-N belongs to the class of organic compounds known as indolines. Indolines are compounds containing an indole moiety, which consists of pyrrolidine ring fused to benzene to form 2,3-dihydroindole.
