Product Description
Exhibits antifungal and cytotoxic activity against some tumor cell lines partly attributed to inhibition of Ras-inducible genes. Inhibits proliferation of mouse and human T cells and modulates production of cytokines during T cell activation. Facilitates the ubiquitinylation process of cyclin D1. Has been identified as a potent and selective inhibitor of threonine/tyrosine-specific kinase, MEK, and other protein kinases that contain a conserved cysteine residue in the ATP-binding site in both in vitro and in vivo studies.

General Information
BACKGROUND/TECHNICAL INFORMATION Indirubin is derived from various natural sources, such as Indigofera indica, Isatis tinctoria and I. indigotica by fermentation, oxidation and the presence of light as a by product of indigo formation. Indirubin is also present in human urine and fetal bovine serum [4]. Preclinical studies of indirubin its confirmed anti-tumor activity. Efficacy against chronic myelocytic leukemia was demonstrated in clinical trials in China [2].

Product Description
Anticancer agent. Inhibits carcinogenesis at the initiation stage but has been shown to enhance tumor incidence at a post-initiation stage. Inhibits the expression of cyclin-dependent kinase 6 (CDK6) and induces G1 cell cycle arrest independent of estrogen receptor signalling. Causes a dose-dependent increase in E-cadherin and BRCA1 expression.
