Product Description: Suramin (sodium salt) (Standard) is the analytical standard of Suramin (sodium salt). This product is intended for research and analytical applications. Suramin sodium salt (Suramin hexasodium salt) is a reversible and competitive protein-tyrosine phosphatases (PTPases) inhibitor[1]. Suramin sodium salt is a potent inhibitor of sirtuins: SirT1 (IC50=297 nM), SirT2 (IC50=1.15 μM), and SirT5 (IC50=22 μM)[2]. Suramin sodium salt is a competitive inhibitor of reverse transcriptase (DNA topoisomerase II: IC50=5 μM)[3][4]. Suramin sodium salt is a potent SARS-CoV-2 RNA-dependent RNA polymerase (RdRp) inhibitor[5]. Suramin sodium salt efficiently inhibits IP5K and is an antiparasitic, anti-neoplastic and anti-angiogenic agent[6][7][8].
