DMH-1 is a potent and selective Bone Morphogenetic Protein (BMP) inhibitor.

Sphingosine-1-phosphate (S1P) is an agonist for S1P1-5 receptors and a ligand for GPR3, GPR6, and GPR12. As an intracellular second messenger, it mobilizes Ca2+ and acts as an extracellular ligand for G-protein coupled receptors. This important lipid mediator is generated from sphingosine or other membrane phospholipids.

Suramin Sodium Salt (BAY-205) is a sodium salt form of suramin, a polysulphonated naphthylurea with potential antineoplastic activity. Suramin blocks the binding of various growth factors, including insulin-like growth factor I (IGF-I), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and tumor growth factor-beta (TGF-beta), to their receptors, thereby inhibiting endothelial cell proliferation and migration. This agent also inhibits vascular endothelial growth factor (VEGF)- and basic fibroblast growth factor (bFGF)-induced angiogenesis; retroviral reverse transcriptase; uncoupling of G-proteins from receptors; topoisomerases; cellular folate transport; and steroidogenesis.

GW9662 (TIMTEC-BB SBB006523) is a specific PPARγ antagonist (IC50: 3.3 nM, in a cell-free assay), with 100 to 1000-fold functional selectivity for PPARγ than PPARα δ in cells.
