Product overview

  • Name
  • Short description
    Non-selective protein kinase inhibitor
  • Biological description
    Non-selective protein kinase inhibitor (IC50 values are 10-30 nM for serine/threonine protein kinases). PKC and Ca2+ / calmodulin-stimulated phosphodiesterase inhibitor (IC50 values are 32.9 nM and 1.8 - 2.8 µM respectively). Competitively inhibits myosin light chain kinase (MLCK) - may interact with the ATP-binding domain (Ki = 20 nM). Blocks neuronal differentiation by potently inhibiting NGF receptor gp140trk tyrosine protein kinase (IC50 = 3nM). Cell permeable and shows potential anti-tumor actions.
