CPT-Se4, a selenoproagent of Camptothecin (CPT), shows improved potency in killing cancer cells and inhibiting tumor growth. CPT-Se4 decreases the GSH/GSSG ratio and total thiols, elevates the ROS level in Hep G2 cells, and eventually induces apoptosis of cancer cells. CPT-Se4 shows cytotoxicity against HeLa, Hep G2, A549, and SMMC-7721 cells (IC50= 2.54-6.4 μM)[1]. | [References]
