A Solubility Comparison of Neutral and Zwitterionic Polymorphs

open access: yes, 2016
Several amphoteric model compounds and drugs, such as isomers of aminobenzoic acids (ortho, meta, and para), N-aryl-2-amino-nicotinic acids (three isomers), amino-salicylic acids (meta and para), clonixin, and niflumic acid, were selected to obtain their

COMPLETE ASSIGNMENT OF 1H- AND 13C-NMR SPECTRA OF ANTHRANILIC ACID AND ITS HYDROXY DERIVATIVES AND SALICYLIC ACID AND ITS AMINO DERIVATIVES

open access: yes, 2016
We report on the detailed NMR spectral analyses of amino- or/and hydroxy-substituted benzoic acids: anthranilic (AA), 3-hydroxyanthranilic (3-HAA), 5-hydroxyanthranilic (5-HAA), salicylic (SA), 4-aminosalicylic (4-ASA) and 5-aminosalicylic (5-ASA) acids.

5-ASA decreases colonic sulfide formation: implications for ulcerative colitis.

open access: yes, 1996
Experimental evidence suggests that anionic sulfide (SH-) may be implicated in the pathogenesis of ulcerative colitis. Sulfides are formed in the colon by sulfate-reducing bacteria acting on sulfate or sulfur amino acids.

Synthesis and structural elucidation of glutathione and N-aceyl-cysteine conjugates of 5-aminosalicylic acid

open access: yes, 1993
The ability of 5-aminosalicylic acid (5-ASA) to be oxidized to a quinone monoimine compound capable of conjugating with nucleophilic compounds such as N-acetyl-cysteine (NAC) and glutathione (GSH) has been investigated in vitro. Three isomeric conjugates

Synthesis, in-vitro bioactivity evaluation and molecular docking of monosaccharide ester and fatty acid amide derivatives of 5-aminosalicylic acid [PDF]

open access: yes, 2016
5-aminosalicylic acid (5-ASA), structurally related to the salicylates, is active in the treatment of inflammatory bowel disease (IBD). Since IBD is a high-incidence disease and considering that 5-ASA has been approved as one of the most effective and ...

Optimization of a free separation of 30 free amino acids and peptides by capillary zone electrophoresis with indirect absorbance detection: a potential for quantification in physiological fluids

open access: yes, 2002
This report describes a rapid, single-run procedure, based on the optimization of capillary electrophoresis (CE) and indirect absorbance detection capabilities, which was developed for the separation and quantification of 30 underivatized physiological ...
