Abstract:
Two indigoid pigments, red indirubin and blue indigotin, were isolated from the urine of healthy male subjects. The two pigments were assayed on HL60 (human promyelocytic cell line) cells. Preliminary results revealed the antiproliferative effect of the pigments. Indigotin seemed more effective than indirubin.
