Suramin is a bis-polysulfonated naphthylurea that can bind to and inhibit PDGF, FGF, EGF, TGF-β, SIRT1, and SIRT5 (Stein). Suramin also blocks G protein binding to G protein-coupled receptors (GPCRs), inhibits the binding of calmodulin to recognition sites on the ryanodine receptor-1 (IC₅₀ = 4.9 μM), and non-selectively antagonizes P2X and P2Y purinergic receptors (10 - 100·μM; Klinger et .; Charlton et al.). This product is supplied as the sodium salt of the molecule.
