Description1-Hydroxy-8-{[(2S,4R,5S,6R)-4-hydroxy-5-{[(2S,4R,5R,6R)-5-hydroxy-4-{[(2S,5S,6S)-5-{[(2S,4R,5S,6R)-4-hydroxy-5-{[(2S,4R,5R,6R)-5-hydroxy-4-{[(2S,5S,6S)-5-hydroxy-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-3-methyl-7,12-dihydrotetraphene-7,12-dione belongs to the class of organic compounds known as angucyclines. These are polyketides with a structure based on then benz[a]anthracene skeleton, with the particularity that the central ring of the anthracene moiety is a para-quinone. Landomycin T is found in Streptomyces and Streptomyces cyanogenus. It was first documented in 2011 (PMID: 21188999). Based on a literature review very few articles have been published on 1-hydroxy-8-{[(2S,4R,5S,6R)-4-hydroxy-5-{[(2S,4R,5R,6R)-5-hydroxy-4-{[(2S,5S,6S)-5-{[(2S,4R,5S,6R)-4-hydroxy-5-{[(2S,4R,5R,6R)-5-hydroxy-4-{[(2S,5S,6S)-5-hydroxy-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-6-methyloxan-2-yl]oxy}-3-methyl-7,12-dihydrotetraphene-7,12-dione.
