Thiobenzanilide 63T (63T) is a small molecule that selectively induces cancer cell death in a caspase-independent pathway. Thiobenzanilide 63T induces reactive oxygen species and lipid peroxidation. Thiobenzanilide 63T demonstrates strong cytotoxic activity against a lung-derived cancer cell line. Thiobenzanilide 63T decreases the expression of heme oxygenase (HO-1) in A549 cells.
