Adenylosuccinic Acid (Synonyms: Aspartyl Adenylate)

Adenylosuccinic acid is a purine nucleotide and an intermediate in the purine nucleotide cycle.[1] It is converted into AMP and fumarate by adenylosuccinate lyase in the cytosol. Adenylosuccinic acid (10 µM) inhibits calcium-induced activation of non-selective cation channels in isolated rat brown adipocytes in a patch-clamp assay.[2] Adenylosuccinic acid (10 µM) increases glucose-induced insulin exocytosis in 832/13 INS-1 pancreatic β-cells.[3] It induces contractions in isolated guinea pig uterus strips when used at a concentration of 100 µM.[4]
