Description

2-[(1S)-10,12-dihydroxy-3,6,11-trioxo-3,4,6,11-tetrahydro-1H-2-oxatetracen-1-yl]ethanimidic acid belongs to the class of organic compounds known as isochromanequinones. These are polycyclic compounds containing an isochromanequinone, which is structurally characterized by a quinone fused to an isochromane, and forming a naphtho[2,3-c]pyran-6,9-dione skeleton. Ekatetrone is found in Kitasatospora aureofaciens, Streptomyces and Streptomyces aureofaciens. It was first documented in 1978 (PMID: 101501). Based on a literature review very few articles have been published on 2-[(1S)-10,12-dihydroxy-3,6,11-trioxo-3,4,6,11-tetrahydro-1H-2-oxatetracen-1-yl]ethanimidic acid.
