SYK Inhibitor, R406 for cell activation

R406 is a potent SYK (Spleen Tyrosine Kinase) inhibitor (IC₅₀ = 41 nM). R406 strongly inhibits SYK but not Lyn, and displays 5-fold less potency towards FLT3. R406 induces apoptosis in diffuse large B-cell lymphoma cell lines. It blocks B cell receptor signaling through inhibition of SYK autophosphorylation of Y525/Y526 and SYK-dependent phosphorylation of the B-cell linker protein.

For cells, cell lines and tissues in culture till half confluency.Tissue, pathway, proteinase, peptidase, protease ,acrosin, lipoprotein, activator, caspase, trypsin, papain, esterase inhibitors are proteins or receptor ligands or receptor antagonists that bind to an enzyme receptor and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. Not all receptor antagonist that bind to enzymes are inhibitors; enzyme activator ligands or agonists bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme.
