Description
Curator's Comment: description was created based on several sources, including: https://en.wikipedia.org/wiki/Indirubin | https://www.ncbi.nlm.nih.gov/pubmed/10559866

Indirubin is derived from the Indigo Plant (Isatis Root, Isatis Leaf). It is used as part of a traditional Chinese herbal prescription called Dang Gui Long Hui Wan, to treat chronic myelogenous leukemia (CML). Indirubin inhibits DNA synthesis in several cell lines, in a cell-free assay and in vivo in rats with Walker-256 sarcoma. A weak binding of indirubin to DNA in vitro has been described. Indirubin inhibited all cyclin-dependent kinases (1,2,4,5) almost equally. Indirubin has been approved for clinical trials against chronic myelocytic and chronic granulocytic leukaemia. A few studies show that Indirubin is effective against psoriasis. Mild to severe nausea, vomiting, abdominal pain, diarrhea, headache, and edema are reported adverse events of Indirubin. Long-term oral ingestion has also occasionally been associated with hepatitis, pulmonary arterial hypertension and cardiac insufficiency.

Originator

Curator's Comment: In 1966, the Institute of Haematology of the Chinese Academy of Medical Sciences embarked on the identification of the active factor of a mixture of 11 herbal medicines Danggui Longhui Wan. The activity was traced to one ingredient, Qing Dai (indigo naturalis), a dark blue powder prepared from the leaves of Baphicacanthus cusia (Acanthaceae), Polygonum tinctorium (Polygonaceae), Isatis indigotica (Brassicaceae), Indigofera suffrutticosa (Fabaceae) and Indigofera tinctoria (Fabaceae). This powder contained a high level of the blue dye indigo, but the antileukaemic activity was attributed to the redcoloured isomer of indigo, indirubin, a minor constituent of the mixture.

Oral: 150–200 mg per day Topical: apply 0.5 g of ointment per 10 x 10 cm psoriatic lesion twice daily (Indirubin 10 or 50 or 100 or 200 ug/g of oinment)
Route of Administration: Other
Indirubin exhibited activity against dermatophytes such as Epidermophyton floccosum (MIC=6.25 ug/ml); Trichophyton rubrum and Trichophyton tonsurans (MIC=25 ug/ml); Trichophyton mentagrophytes and Trichophyton simii (MIC=50 ug/ml). It was also active against non-dermatophytes (Aspergillus niger, Candida albicans and Cryptococcus sp.) within a MIC range of 0.75-25 ug/ml.
