Cathepsin B Activator

Ferroptosis inducer-16 (anti-NSCLC agent-2) is a nitric oxide (NO) donor and a ferroptosis inducer. Ferroptosis inducer-16 inhibits DNA synthesis and colony formation. Ferroptosis inducer-16 disrupts lysosomal integrity by releasing NO, triggers iron overload and oxidative stress, downregulates the SLC7A11-GPX4 axis, depletes GSH, and accumulates lipid peroxides. Ferroptosis inducer-16 inhibits tumor growth in an OVCAR8/ADR xenograft mouse model without obvious toxicity, and can be used in the study of non-small cell lung cancer and drug-resistant ovarian cancer.

Ferroptosis inducer-17 is a ferroptosis inducer that downregulates GPX4 and activates the CTSB and cGAS-STING pathways. Ferroptosis inducer-17 exhibits cytotoxicity against cancer cells but low toxicity toward normal cells. Ferroptosis inducer-17 accumulates in mitochondria and lysosomes, thereby inducing ROS production, lipid peroxidation, mitochondrial membrane depolarization, lysosomal iron accumulation, increased membrane permeability, and enhanced oxidative stress. Ferroptosis inducer-17 inhibits tumor growth in cisplatin-resistant xenograft models. Ferroptosis inducer-17 can be used for cancer-related research.
