Hematoxylin, an Alternative Substrate of Tyrosinase.

Mushroom tyrosinase from (TYR) is often used during the development of tyrosinase inhibitors for medicinal and cosmetic purposes. In the search for novel tyrosinase inhibitors, this study identified hematoxylin as an alternative substrate for TYR. The interaction of hematoxylin with TYR was investigated through spectrophotometric and chromatographic analyses.
