Common Name2-amino-n-{1-[({[(1e)-2-(6-bromo-1h-indol-3-yl)ethenyl]-c-hydroxycarbonimidoyl}methyl)-c-hydroxycarbonimidoyl]-2-(3,4-dihydroxyphenyl)ethyl}-3-(3h-imidazol-4-yl)propanimidic acid
DescriptionHalocyamine A belongs to the class of organic compounds known as oligopeptides. These are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. 2-amino-n-{1-[({[(1e)-2-(6-bromo-1h-indol-3-yl)ethenyl]-c-hydroxycarbonimidoyl}methyl)-c-hydroxycarbonimidoyl]-2-(3,4-dihydroxyphenyl)ethyl}-3-(3h-imidazol-4-yl)propanimidic acid is found in Halocynthia roretzi. 2-amino-n-{1-[({[(1e)-2-(6-bromo-1h-indol-3-yl)ethenyl]-c-hydroxycarbonimidoyl}methyl)-c-hydroxycarbonimidoyl]-2-(3,4-dihydroxyphenyl)ethyl}-3-(3h-imidazol-4-yl)propanimidic acid was first documented in 2017 (PMID: 28695949). Based on a literature review very few articles have been published on Halocyamine A.
