NCIt definition : A low-molecular-weight organic compound with potential antineoplastic activity. Upon
intra-tumoral injection, para-toluenesulfonamide increases lysosomal membrane permeabilization
(LMP) and the release of cathepsin B. Cytosolic cathepsin B released from lysosomes
cleaves and activates proapoptotic B-cell lymphoma 2 (Bcl-2) family member BH3 interacting-domain
death agonist (Bid) and poly [ADP-ribose] polymerase 1 (PARP-1), which may induce
tumor cell death.;
