CIGB-552

• Description:

  CIGB-552 is a cell-penetrating peptide with anti-tumor properties with the IC50 of 23 μM in H460 cells. CIGB-552 can increase the level of protein COMMD1. CIGB-552 significantly inhibits the NF-κB signaling pathway. CIGB-552 can promote apoptosis of the tumor cells. CIGB-552 can induce the accumulation of reactive oxygen species (ROS) in tumor cells. CIGB-552 has anti-inflammatory and anti-angiogenic effects. CIGB-552 can be used for the research of the lung cancer and colon cancer[1][2][3][4].
