Methyl 2-acetamido-2-deoxy-β-D-glucopyranoside dihydrate and methyl 2-formamido-2-deoxy-β-D-glucopyranoside.
Methyl 2-acetamido-2-deoxy-β-D-glucopyranoside (β-GlcNAcOCH(3)), (I), crystallizes from water as a dihydrate, C(9)H(17)NO(6)·H(2)O, containing two independent molecules [denoted (IA) and (IB)] in the asymmetric unit, whereas the crystal structure of methyl 2-formamido-2-deoxy-β-D-glucopyranoside (β-GlcNFmOCH(3)), (II), C(8)H(15)NO(6), also obtained from water, is devoid of solvent water molecul...
متن کامل2-Acetamido-2-deoxy-3-O-β-d-galactopyranosyl-d-glucose dihydrate
In the title compound, C(14)H(25)NO(11)·2H(2)O, the primary hydroxyl group connected to the anomeric C atom of the N-acetyl-β-d-glucopyran-ose residue exhibits positional disorder, with occupancy factors for the α and β anomers of 0.77 and 0.23, respectively. The two torsion angles (Φ and Ψ) and the bridge angle (τ) that describe conformation of the glycosidic linkage between the galactopyran-o...
متن کاملThe cardioprotective effects of 4-O-(2″-O-acetyl-6″-O- p-coumaroyl-β-D-glucopyranosyl)-p-coumaric acid (4-ACGC) on chronic heart failure
The 4-ACGC isolated from BP was prepared to investigate the cardioprotective effects on attenuating chronic heart failure in vivo and in vitro. A chronic heart failure (CHF) rat model was established to investigate the cardioprotective effects of 4-ACGC. From this, several cardiac function indexes were recorded. The inflammatory markers including tumor necrosis factor-α (TNF-α), Interleukin-6 (...

متن کاملMethyl 3-O-α-d-mannopyranosyl β-d-glucopyranoside tetrahydrate
The title compound, C(13)H(24)O(11)·4H(2)O, forms extended hydrogen-bonded networks. These are present between disaccharides, but not as inter-residue hydrogen bonds, as well as to water mol-ecules that in addition form an inter-molecular chain of hydrogen bonds. The conformation of the disaccharide is described by the glycosidic torsion angles ϕ(H) = -34° and ψ(H) = -5°. Macroscopically, the d...
