Electrochemical Synthesis of 5-Aminosalicylic Acid from 5- Nitrosalicylic Acid in Alkaline Media
5-Aminosalicylic acid (5-ASA) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-NSA) in acidic media. In this work, electrolytic reduction of 5-NSA in alkaline media is presented. Reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the pH for isolation of product are investigated. The yiel...
متن کاملInosinic Acid Dehydrogenase Activity
ated in normal subjects and in patients with the LeschNyhan syndrome. A significant difference in activity was found between erythrocytes derived from normal controls (1.21±0.47 pmoles/hr per mg protein) and from 15 patients with the Lesch-Nyhan syndrome (6.72 ±6.23 pmoles/hr per mg protein). However, no difference in activity was demonstrable in muscle or leukocytes derived from normal and Les...
متن کاملInosinic acid dehydrogenase of sarcoma 180 cells.
Inosinic acid dehydrogenase was partially purified from sarcoma 180 cells. The concentrations of each reactant, inosine 5’-phosphate, nicotinamide adenine dinucleotide, and K+, altered both the apparent K, and Vmaxvalues for each of the other reactants. Enzymatic activity was inhibited by both products of the reaction, xanthosine S-phosphate and reduced nicotinamide adenine dinucleotide; the in...

متن کامل5’-adenylic Acid Deaminase
In 1928, Schmidt (1) first described the presence of 5’-adenylic acid deaminase in muscle. He succeeded in separating this enzyme from adenosine deaminase and in isolating inosinic acid and ammonia as products of the reaction. He also reported that it specifically deaminated 5’-adenylic acid. In 1947, Kalckar (2) described two methods for the preparation of this enzyme and introduced a spectrop...
