Description Indirubin is the active ingredient of Danggui Longhui Wan, a traditional Chinese medicine containing plants such as Indigofera tinctoria L. and Isatis tinctoria L, which are used in traditional Chinese medicine to treat chronic diseases. Indirubin and its analogues are reported as potent inhibitors of cyclin-dependent kinases (CDKs). This could attribute to the positive effect of indirubin on counteracting proliferative diseases, such as chronic myelocytic leukemia (CML), a slowly progressive disease characterized by the overproduction of granulocytes.
