Suramin sodium salt
Based on 22 publication(s) in Google Scholar
Suramin sodium salt (Suramin hexasodium salt) is a reversible and competitive protein-tyrosine phosphatases (PTPases) inhibitor. Suramin sodium salt is a potent inhibitor of sirtuins: SirT1 (IC50=297 nM), SirT2 (IC50=1.15 μM), and SirT5 (IC50=22 μM). Suramin sodium salt is a competitive inhibitor of reverse transcriptase (DNA topoisomerase II: IC50=5 μM). Suramin sodium salt is a potent SARS-CoV-2 RNA-dependent RNA polymerase (RdRp) inhibitor. Suramin sodium salt efficiently inhibits IP5K and is an antiparasitic, anti-neoplastic and anti-angiogenic agent.
