Adenylosuccinic Acid Tetraammonium (also known as Adenylosuccinate or Aspartyl Adenylate) is an orally active compound that functions as a purine ribonucleoside monophosphate and is involved in nucleotide cycle metabolism. It can be transformed into fumaric acid via adenylosuccinate lyase action. This compound holds potential for research in Duchenne Muscular Dystrophy (DMD) [1].
