Synthesis and anticonvulsant activity of N,N-phthaloyl derivatives of central nervous system inhibitory amino acids.
In order to study the influence of the length of the amino acid chain of N,N-phthaloyl-amino acid amides as analogues of the former anticonvulsant taltrimide on the seizure-antagonizing activity glycine, beta-alanine and gamma-aminobutyric acid (GABA) derivatives were synthesized. The corresponding taurine derivatives were also included. Generally, the glycine-derived amides showed a higher act...

متن کاملMetabolism 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 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 ...
متن کاملN-acetylglucosamine and glucosamine-containing arabinogalactan proteins control somatic embryogenesis.
In plants, complete embryos can develop not only from the zygote, but also from somatic cells in tissue culture. How somatic cells undergo the change in fate to become embryogenic is largely unknown. Proteins, secreted into the culture medium such as endochitinases and arabinogalactan proteins (AGPs) are required for somatic embryogenesis. Here we show that carrot (Daucus carota) AGPs can conta...
