Metabolism of D-glucosamine and N-acetyl-D-glucosamine in the intact rat.
It has been demonstrated that n-glucosamine and N-acetyln-glucosamine are metabolized in animal tissues to n-fructose via phosphorylated intermediates (14). It has also been shown that n-glucose is converted to n-glucosamine and incorporated into glycoproteins and mucopolysaccharides (Pll), probably through formation of uridine diphosphate derivatives as intermediates (4). Little work has been ...
متن کاملGlucosamine and N-acetyl glucosamine as new CEST MRI agents for molecular imaging of tumors
The efficacy of glucosamine (GlcN) and N-acetyl glucosamine (GlcNAc) as agents for chemical exchange saturation transfer (CEST) magnetic resonance molecular imaging of tumors is demonstrated. Both agents reflect the metabolic activity and malignancy of the tumors. The method was tested in two types of tumors implanted orthotopically in mice: 4T1 (mouse mammary cancer cells) and MCF7 (human mamm...
متن کاملN-Acetyl Glucosamine Obtained from Chitin by Chitin Degrading Factors in Chitinbacter tainanesis
A novel chitin-degrading aerobe, Chitinibacter tainanensis, was isolated from a soil sample from southern Taiwan, and was proved to produce N-acetyl glucosamine (NAG). Chitin degrading factors (CDFs) were proposed to be the critical factors to degrade chitin in this work. When C. tainanensis was incubated with chitin, CDFs were induced and chitin was converted to NAG. CDFs were found to be loca...
متن کاملSynthesis of oseltamivir and tamiphosphor from N-acetyl-D-glucosamine.
Using N-acetyl-D-glucosamine as a starting material, the anti-influenza drugs oseltamivir and tamiphosphor were synthesized via a pivotal intermediate of aldehyde 8. An intramolecular Horner-Wadsworth-Emmons reaction was utilized to construct the highly functionalized cyclohexene ring. The existing N-acetyl group was transformed into an azido group for the subsequent aziridination, followed by ...
متن کاملA novel uridine nucleotide containing N-acetyl-glucosamine and galactose.
While the yolk traverses the hen oviduct, albumen, shell membranes, and the calcified shell are successively secreted (3). The isthmus, a short section 2 to 8 cm in length, synthesizes and secretes the inner shell membrane, a lace-like envelope composed of fibers of an acid glycoprotein (see below). A number of nucleotides have been shown to occur in the isthmus, including cytosine diphosphate ...
