Tool Details

  • Tool name: Chk2 inhibitor CCT241533 Small Molecule (Tool Compound)
  • Molecular formula: C23H27FN4O4
  • Tool type: Small molecules
  • Tool sub-type: Inhibitor
  • Purpose: Inhibitor
  • Description: The Chk2 inhibitor CCT241533 was shown to produce a mechanistic inhibition of CHK2 in HT29 human colon cancer cells as well as a radioprotective effect in mouse thymocytes. In normal cells, p53 is activated by CHK2 and other kinases in response to double-strand DNA damage resulting in G1 cell cycle arrest and apoptosis. Inhibition of CHK2 may provide an antitumor effect in cancer cells, and therefore a therapeutic approach.
