Indirubin
Indirubin or indigo red is an organic compound with a distinctive deep red/orange color. It is an oxindole dimer consisting of two fused oxindole rings. Indoles are compounds which consist of a pyrrole ring fused to benzene to form 2,3-benzopyrrole. Indirubin is found in both plants and animals and has been detected in human urine and human tissues (PMID: 11076521; PMID: 8667928). The precursor to indirubin is indican, a colorless, water-soluble derivative of the amino acid tryptophan which is converted to indole via microbial metabolism. Indican readily hydrolyzes to release β-D-glucose and indoxyl. Oxidation of indoxyl by CYP450 enzymes in the liver or kidneys can convert indoxyl to indirubin (PMID: 11076521). Likewise, exposure to air can convert indoxyl to indirubin. In addition to the mammalian production of minute amounts of indirubin, this chemical can also be recovered in far larger amounts from plants. Historically, indirubin has been extracted from the leaves of certain plants of the Indigofera genus, in particular Indigofera tinctoria. Indigofera plants were commonly grown and used throughout the world for the production of dyes. Indirubin is a chemical constituent of indigo naturalis (also known as qing dai), which has been used for hundreds of years in traditional Chinese medicine. It is produced by collecting the waste products from the bacterial degradation of specific forms of vegetation. Indirubin has shown anti-inflammatory and anti-angiogenesis properties in vitro (PMID: 21207415). It has also been studied for potential use in the treatment of ulcerative colitis (PMID: 23674882).

Halofuginone also effectively suppresses tumor progression and metastasis in mice. Collgard Biopharmaceuticals is developing halofuginone for the treatment of scleroderma and received orphan drug designation from the U.S. Food and Drug Administration in March, 2000. Halofuginone is a natural product found in Hydrangea febrifuga with data available. Halofuginone is an orally-active quinazolinone alkaloid with potential antineoplastic activity. Halofuginone interferes with the signaling pathway of transforming growth factor beta (TGF beta) and inhibits expression of matrix metalloproteinase 2, thereby inhibiting collagen type I synthesis and inducing extracellular matrix degradation, resulting in inhibition of angiogenesis, tumor growth, or metastasis.
