N-Glycosyl-3-alkylideneoxindoles, N-glycosylated 3-(2-oxo-2-arylethylidene)indolin-2-ones, were prepared by reaction of isatin-N-glycosides with substituted acetophenones.
by condensation of N‐glycosylisatines with thiaindane‐3‐one and subsequent deprotection, were tested for their activity against malignant melanomacells. These indirubin‐N‐glycoside thia‐analogues are active against melanomacells, inducing growth arrest, apoptosis and inhibition of intracellular signal transduction.
The invention relates to a chromatographic separation process of recovering mannose with high purity. The invention is based on the use of a chromatographic separation resin including a resin which is at least partly in a Ba

A novel procedure has been proposed for the synthesis of chiral alpha-aminophosphoryl compounds from glycosylamines and PH compounds (diphenylphosphine oxide and ethyl and phenyl phenylphosphonates) under mild conditions. The reaction is accompanied by dehydration of the carbohydrate moiety in unprotected monosaccharides to form furan ring.
First synthesis of indirubin N-glycosides (red sugars)
