| Description | Isatan B belongs to the class of organic compounds known as hexoses. These are monosaccharides in which the sugar unit is a is a six-carbon containing moeity. (2r,3r,5s,6s)-3,5-dihydroxy-2-(hydroxymethyl)-6-(1h-indol-3-yloxy)oxan-4-one is found in Isatis tinctoria and Persicaria tinctoria. (2r,3r,5s,6s)-3,5-dihydroxy-2-(hydroxymethyl)-6-(1h-indol-3-yloxy)oxan-4-one was first documented in 2004 (PMID: 17191785). Based on a literature review a small amount of articles have been published on Isatan B (PMID: 31035058) (PMID: 20575402) (PMID: 18514538) (PMID: 15745425). |
