Synthesis of Capsaicin Oligosaccharides and Their Anti-Allergic Activity——Synthesis of Capsaicin Oligosaccharides as Anti-Allergic Food-Additives
The production of β-maltooligosaccharides of capsaicin was investigated using Lactobacillus delbrueckii and cyclodextrin glucanotransferase (CGTase) as biocatalysts. The cells of L. delbrueckii glucosylated capsaicin to give its β-glucoside. The β-glucoside of capsaicin was converted into the corresponding β-maltoside and β-maltotrioside by CGTase. On the other hand, β-melibioside and β-isomalt...
متن کاملEnzymatic synthesis of oligosaccharides
The biological interest of oligosaccharides is growing very rapidly, and necessitates the development of efficient synthesis reactions. The stereoand regio-selectivity of enzyme catalysis is a key advantage in this field, as a complementary tool to the chemical approach. Two types of enzymes can be applied to the obtention of oligosaccharides: Hydrolytic enzymes, which can catalyze either rever...
متن کاملSynthesis and anti-platelet, anti-inflammatory and anti-allergic activities of methoxyisoflavanquinone and related compounds.
In a continuation of our search for novel anti-platelet agents, isoflavone quinone and isoflavanquinone were selected as lead compounds and the synthesis of their methoxy derivatives was carried out. Among them, the 4'- and 7-methoxy derivatives were successfully prepared, whereas the attempt to obtain 3'-methoxy derivatives resulted in their isomers, 3'-methoxyflavone quinone and 3'-methoxyfla...
متن کاملSynthesis of beta-maltooligosaccharides of glycitein and daidzein and their anti-oxidant and anti-allergic activities.
The production of beta-maltooligosaccharides of glycitein and daidzein using Lactobacillus delbrueckii and cyclodextrin glucanotransferase (CGTase) as biocatalysts was investigated. The cells of L. delbrueckii glucosylated glycitein and daidzein to give their corresponding 4'- and 7-O-beta-glucosides. The beta-glucosides of glycitein and daidzein were converted into the corresponding beta-malto...
متن کاملSynthesis of Xylooligosaccharides of Daidzein and Their Anti-Oxidant and Anti-Allergic Activities
The biocatalytic synthesis of xylooligosaccharides of daidzein was investigated using cultured cells of Catharanthus roseus and Aspergillus sp. β-xylosidase. The cultured cells of C. roseus converted daidzein into its 4'-O-β-glucoside, 7-O-β-glucoside, and 7-O-β-primeveroside, which was a new compound. The 7-O-β-primeveroside of daidzein was further xylosylated by Aspergillus sp. β-xylosidase t...
