Use

Purpurin is a naturally occurring reddish-yellow pigment found in madder root (R. tinctorum) that has been used both in herbal remedies and as food coloring. It can also by synthetically derived from 9,10-anthraquinone. Purpurin is protective against a number of food-derived heterocyclic amines in bacterial mutagenicity assays through its inhibition of CYP450-dependent N-hydroxylation and reduction of N-hydroxylamines. Purpurine can also inhibit (IC50 = 6.6 μM) spermidine-induced autoactivation of plasma hyaluronan-binding protein, a serine protease that can activate coagulation factor VII and prourokinase.
