Definition:A member of the class of hydroxyindoles resulting from the formal oxidative coupling between the 3-position of 1,3-dihydro-2H-indol-2-one and the 3-position of 1,3-dihydro-2H-pyrrol-2-one, which is substituted at the 5 position by a 5-hydroxy-1H-indol-3-yl group, where the newly-formed double bond has E configuration. It is a purple chromobacterial pigment that has antibacterial, antifungal, antiprotozoan, and anticancer properties.
Synonyms:exact_synonym: (3E)-3-[5-(5-hydroxy-1H-indol-3-yl)-2-oxo-1,2-dihydro-3H-pyrrol-3-ylidene]-1,3-dihydro-2H-indol-2-one
