    • Bio Activity:

      Protein kinase inhibitor Tocris Bioscience 1227
      Protein kinase inhibitor. Suppresses tumor-promoting effects of TPA and exhibits antiproliferative activity in human breast cancer cells (IC50 values are 59.44 and 31.15 ?M at 24 and 72 hrs respective ly). Activates both the intrinsic and extrinsic apoptotic pathways and displays anti-inflammatory, hypotensive, antispasmodic and antioxidant properties in vivo. Tocris Bioscience 1227
