Methyl 6-O-trityl-α-d-glucopyranoside methanol disolvate
The asymmetric unit of the title compound, C26H28O6·2CH3OH, contains two independent methyl 6-O-trityl-α-d-gluco-pyran-oside mol-ecules and four methanol solvent mol-ecules. The rings of two methyl α-d-gluco-pyran-oside adopt chair conformations. In the crystal, extensive intra- and inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular archi...
متن کاملErythrocyte 3-O-methyl-D-glucose uptake assay for diagnosis of glucose-transporter-protein syndrome.
Glucose transport into the brain is mediated by a facilitative glucose-transporter protein, GLUT-1. A GLUT-1 defect results in the Glucose-Transporter-Protein Syndrome (GTPS), characterized by infantile epilepsy, developmental delay, and acquired microcephaly. The diagnosis is currently based on clinical features, low to normal lactate levels and low glucose levels (hypoglycorrhachia) in the ce...
متن کاملThe effect of 2-deoxy-d-glucose and 3-O-methyl-d-glucose on mucosubstance secretion in cell culture.
Ouabain at lm inhibits the secretion of hyaluronic acid by Rous-sarcoma-virustransformed hamster fibroblasts in 5.5 m-glucose medium, but not in glucose-free medium (Duguid & Marsden, 1972). As the amount of secretion in glucose-free medium is 90-95 % of that in glucose-containing medium, it appears that a complex relationship exists between mucosubstance secretion, ion transport and glucose me...
متن کامل6-[Bis(ethoxycarbonyl)methyl]-6-deoxy-1,2;3,4-di-O-isopropylidene-d-galactopyranose
The title compound, C(19)H(30)O(9), was prepared by substitution at the C6 position in 1,2;3,4-di-O-isopropyl-idene-6-O-trifluoro-methane-sulfonyl-d-galactose using sodium eth-oxy-malonate in dimethyl-formamide. The conformation is skew-boat (0)S(2), slightly distorted towards boat B(2,5). The inflexible pyran-ose structure makes the title compound a suitable inter-mediate for further synthetic...
متن کاملMethyl 6-deoxy-6-iodo-2,3-O-isopropylidene-α-d-mannopyranoside
In the title compound, C10H17IO5, the six-membered tetra-hydro-pyran ring and the five-membered 1,3-dioxolane ring adopt sofa and envelope conformations, respectively. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into layers nearly parallel to the bc plane.
