Suramin, Sodium Salt - CAS 129-46-4 - Calbiochem

General description

A reversible and competitive inhibitor of protein tyrosine phosphatases. An anti-neoplastic, anti-angiogenic agent that uncouples G-proteins from receptors presumably by blocking their interaction with intracellular receptor domains. Inhibits GDP-GTP exchange, the rate limiting step in the activation of G_α-subunits. A competitive inhibitor of reverse transcriptase. Reported to inhibit topoisomerases I and II. Inhibits Ca²⁺-ATPase in sarcoplasmic reticulum membranes. Also inhibits the cell-surface binding of various growth factors, including EGF, PDGF, and TGF-β. An inhibitor of phospholipase D (IC₅₀ = 15 µM). Reported to interact with ATP-binding enzymes and P₂-purinergic receptors. An effective inhibitor of angiogenesis in the calmodulin assay when given in combination with angiostatic steroids.
