3-[5-(1H-Indole-3-yl)-2,3-dihydro-2-oxo-1H-pyrrole-3-ylidene]-1H-indole-2(2H)-one Chemical Properties, Uses, Production

Uses

Deoxyviolacein is a minor, more hydrophobic co-metabolite of violacein. While its presence has been long recognised in “purified” violacein, separation of deoxyviolacein has not been undertaken. Lack of availability has restricted more extensive investigation of deoxyviolacein.

Uses

Deoxyviolacein is a minor, more hydrophobic co-metabolite of violacein, a useful bacterial pigment.

Definition

ChEBI: Deoxyviolacein is a member of the class of oxindoles resulting from 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 1H-indol-3-yl group, where the newly-formed double bond has E configuration. It has a role as a bacterial metabolite, an antibacterial agent and an antifungal agent. It is an olefinic compound, a member of oxindoles and a member of pyrroles. It is functionally related to a proviolacein.
