Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Zhang, Dongdong, once mentioned the application of 1218-69-5, Name is 2-(2-Hydroxyphenyl)-4H-benzo[e][1,3]oxazin-4-one, molecular formula is C14H9NO3, molecular weight is 239.23, MDL number is MFCD02234511, category is indole-building-block. Now introduce a scientific discovery about this category, COA of Formula: https://www.ambeed.com/products/1218-69-5.html.
Four undescribed sulfur-containing indole alkaloids, isatisindigoticanines H, I and isatindigosides F, G along with three known analogues were obtained from Isatis tinctoria L. roots. Isatisindigoticanines H and I contained an unusual 1-(thiazol-4-yl)butane-1,2,3,4-tetraol moiety while isatindigosides F and G possessed a new 3- [3-(1H-indole-2-yeazet-2-yl]-1H-indole skeleton. The putative biosynthetic pathways of isatisindigoticanines H, I and isatindigosides F, G are proposed. The isolated compounds showed nitric oxide inhibitory effects with IC50 values ranging from 4.3 to 70.3 mu M.
