Utilization and metabolism of [U-14C]4' galactosyllactose (O-beta-D-galactopyranosyl-(1----4)-O-beta-D-galactopyranosyl-(1----4)- D-glucopyranose) in rats.
O-beta-D-Galactopyranosyl-(1----4)-O-beta-D-galactopyranosyl- (1----4)-D-glucopyranose (designated as 4'GL) are produced from lactose with Cryptococcus laurentii OKN-4. Excretion and metabolism of 4'GL in rats were examined using a radioisotope technique. [U-14c]4'GL was synthesized from [U-14C]lactose by Cryptococcus laurentii OKN-4. The 14CO2 in expired air was counted after oral administrati...
متن کاملSynthesis, Structure and Antioxidant Activity of (Tetra-O-acetyl-β-D-galactopyranosyl)thiosemicarbazones of Substituted Benzaldehydes
Some new substituted benzaldehyde (2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl) thiosemicarbazones were synthesised by reaction of 2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl thiosemicarbazide and different substituted benzaldehydes. The reaction was performed using conventional and microwave-assisted heating methods. The structures of thiosemicarbazones were confirmed by spectroscopic (IR, (1)...
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 کاملImproved Synthesis of 1-O-Acyl-β-d-Glucopyranose Tetraacetates.
An improved synthesis of 1-O-acyl glucosyl esters that avoids the use of expensive Ag reagents as well as the hydrolysis of unstable glucosyl bromides is reported. Notably, β-configuration products were obtained exclusively in good yields.
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 (...
