Model melanins, synthesized with different cysteinyldopamine/dopamine ratios in the incubates, were oxidized with KMnO4 and the resulting compounds were analyzed by HPLC. The ratios between a phaeomelanin-derived compound, thiazole-4,5-dicarboxylic a

Background Despite the fact that severe itch is common in many dermatological diseases, the therapeutic arsenal against itching is limited. From neurophysiological experiments, using a new technique termed cutaneous field stimulation, it is known tha

The pigment of the human substantia nigra was isolated after extraction of lipids and proteins with 2% sodium cholate in 30% ethanol followed by 2% sodium dodecyl sulfate in 10% glycerol. The pigment was hydrolysed with HI or degraded by treatment wi

5-S-Cysteinyldopac, a compound hitherto demonstrated only in brain tissue, has been isolated and quantified in urine. The urines from 12 individuals were found to contain 20 +/- 9.1 micrograms 5-S-cysteinyldopac/24 hours. Incubation of 5-S-cysteinyld

The concentrations of dopa, cysteinyldopas, 5-S-glutathionyldopa, gamma-glutamyl-5-S-cysteinyldopa and 5-S-cysteinylglycinedopa, were analysed in homogenates of cultured human melanoma cells and in culture media. Cysteinyldopas were found to be the m

Pregnant women and women taking oral contraceptives show urinary excretion values of 5-S-cysteinyldopa and of 6-hydroxy-5-methoxyindole-2-carboxylic acid in the same range as nonpregnant women not taking oral contraceptives. The excretion of these me

Urinary excretion of the phaeomelanin precursor 5-S-cysteinyldopa (5-S-CD) and the eumelanin metabolite 6-hydroxy-5-methoxyindole-2-carboxylic acid (6H5MI-2-C) was studied in black and albino mice. The urinary concentration of 5-S-CD was 31.7 ng/ml i

5-S-Glutathionyldopa is oxidized at incubation with tyrosinase and dopa producing a black pigment. The reaction proceeds with the formation of two chromophores with absorption spectra similar to those of dopachrome and melanochrome, respectively. Zn2

The urine of an albino woman contained small quantities of 5-S-cysteinyldopa; 6-hydroxy-5-methoxyindole-2-carboxylic acid, a melanin precursor metabolite, was lacking. The 5-S-cysteinyldopa excretion observed may reflect non-specific oxidation of dop
