5-Hydroxy-6-methoxy-2-indolylcarboxylic and 6-hydroxy-5-methoxy-2-indolylcarboxylic acids in the urine of hamsters with melanotic melanoma.
The isomeric metabolites, 5-hydroxy-6-methoxy-2-indolylcarboxylic and 6-hydroxy-5-methoxy-2-indolylcarboxylic acids have been identified in the urine of hamsters bearing transplantable melanotic melanoma. Their identification was carried out by spectral and chromatographic comparison of the two isomers isolated from urine with the same compounds achieved synthetically.
