Description

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.

Sample Use Guides

In Vivo Use Guide
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
In Vitro Use Guide
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.
