CAS 2638-99-5: 6-hydroxy-5-methoxy-1H-indole-2-carboxylic acid

6-Hydroxy-5-methoxyindole-carboxylic acid is a metabolite of the amino acid tyrosine. It is produced in the human body when exposed to radiation and can be used for the diagnosis of melanoma. 6-Hydroxy-5-methoxyindole-carboxylic acid is found in urine samples and can be used as an indicator of metastatic disease, as well as an indicator of prognosis. It is also a biomarker for women with melanoma. 6-Hydroxy-5-methoxyindole-carboxylic acid has been shown to induce tyrosinase and other enzymes involved in the synthesis of eumelanin, which results in increased pigmentation. This compound may also play a role in transcriptional regulation by binding to polymerase chain reaction (PCR) primers or by modulating the activity of transcription factors that bind to DNA sequences near the promoter region of genes
