Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 29390-67-8, Name is Mono-(6-amino-6-deoxy)-¦Â-cyclodextrin, molecular formula is C42H71NO34, belongs to dioxole compound. In a document, author is Zhang, Jun, introduce the new discover, Application In Synthesis of Mono-(6-amino-6-deoxy)-¦Â-cyclodextrin.
Mucroniferanines A-G, lsoquinoline Alkaloids from Corydalis mucronifera
Five pairs of isoquinoline alkaloid enantiomers, mucroniferanines A-E (1-5), two inseparable epimeric pairs, mucroniferanines F and G (6, 7), and 10 known isoquinoline alkaloids (8-17) were obtained from Corydalis mucronifera. The structures were characterized using spectroscopic data analysis, and the absolute configurations were established by ECD and X-ray data analysis. The new compounds except for 3 possess a rare 9 methyl group in the isoquinoline alkaloids, and compounds 2 and 3 possess rare benzo[1,2-d:3,4-d]bis[1,3]dioxole moieties. It is the first report of stereoisomerism involving the 9-methyl phthalideisoquinoline alkaloids. Compounds (-)-4, 6, and 7 exhibited acetylcholinesterase inhibitory activities with IC50 values of 28.3, 12.2, and 11.3 mu M, respectively.
