Inosine 5′-diphosphate, disodium salt (CAS 54735-61-4)

Inosine 5′-diphosphate, disodium salt, is a purine nucleotide used in biochemical and enzymatic research to study the metabolism and regulation of nucleotides within cells. This compound is particularly relevant in the examination of nucleotide interconversion pathways and the enzymes involved in phosphorylation and dephosphorylation processes. The disodium salt form of inosine 5′-diphosphate enhances its solubility, facilitating its use in aqueous solutions for in vitro experiments. It is instrumental in exploring the role of specific nucleotides in the activation of metabolic pathways and as allosteric regulators of enzyme activity. Inosine 5′-diphosphate is also used in the study of enzyme kinetics and mechanisms, especially those of kinases and phosphatases that recognize inosine nucleotides as substrates or inhibitors. Additionally, it serves as a precursor or intermediate in the synthesis of higher phosphorylated nucleotides, such as inosine triphosphate (ITP), and in the investigation of their biological roles.
