Indigo Carmine
Indigo carmine, also known as C.I. Pigment Blue 63, or indigo blue, belongs to the class of organic compounds known as indolines. Indolines are compounds containing an indole moiety, which consists of pyrrolidine ring fused to benzene to form 2,3-dihydroindole. Indigo carmine is an indigo derivative that is produced by sulfonation of indigo, which makes the compound water soluble (up to 10 g/L). Indigo carmine exists as a bright purple solid and is an extremely weak basic (essentially neutral) compound (based on its pKa). It is approved for use as a food colorant in the U.S and E.U. It is also used as a medical dye. In obstetric surgery, indigo carmine solutions are sometimes employed to detect amniotic fluid leaks. In urologic surgery, intravenous injection of indigo carmine is often used to highlight portions of the urinary tract. The dye is filtered rapidly by the kidneys from the blood, and colors the urine blue. This enables structures of the urinary tract to be seen in the surgical field and demonstrates if there is a leak. A frequently encountered cardiovascular effect of intravenous indigo carmine administration is temporary alpha-receptor stimulation. Skin discoloration may occur at high doses. According to one study, the primary action of indigo carmine appears to be at the level of nitric oxide generation and/or its release from the endothelium. In addition to this, indigo carmine appears to inhibit vascular smooth muscle guanylyl cyclase. Therefore, indigo carmine may increase blood pressure by interfering with these nitric oxide-mediated vasodilatory mechanisms. Moreover, incubation of isotopically labeled indigo carmine with intestinal contents of rats for 48 h suggested that isatin-5-sulphonic acid and 5-sulphoanthranilic acid may possibly be metabolites formed by intestinal bacterial metabolism of the drug.

Indigo
Indigo (indigo dye or indigotin) is an organic compound with a distinctive blue 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. Indigo is found in both plants and animals and has been detected in human urine and human tissues (PMID: 11076521; PMID: 8667928). The natural precursor to indigo is indican, a colorless, water-soluble derivative of the amino acid tryptophan. 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 indigo (PMID: 11076521). Likewise, exposure to air can convert indoxyl to indigo. In addition to the mammalian production of minute amounts of indigo, this chemical can also be recovered in far larger amounts from plants. Historically, indigo 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 indigo dyestuff. This was economically important due to the previous rarity of some blue dyestuffs historically. India was the primary supplier of indigo to Europe as early as the Greco-Roman era. The association of India with indigo is reflected in the Greek word for the dye, indikón. The Romans latinized the term to indicum, which passed into Italian dialect and eventually into English as the word indigo. Most indigo dye produced today is synthetic, constituting several thousand tons each year. It is most commonly associated with the production of denim cloth and blue jeans.
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).
