The elevated presence of glutathione S-transferase pi-1 (GSTP1-1) within tumor cells plays a pivotal role in the development of resistance toward the effects of CDDP. GSTP1-1 contributes to detoxification by conjugating glutathione (GSH) to CDDP, reducing its accumulation and effectiveness in the tumor cells.

Furthermore, through the establishment of a nude mouse model featuring lung adenocarcinoma A549/CDDP cell transplantation tumors, gliquidone demonstrated a significant therapeutic effect on the mice tumors, while avoiding discernible side effects.
