An additional H-site binder and another inhibitor of GSTP1-1 and other GSTs, 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthio)hexanol (NBDHEX) possesses antiproliferative properties against various cancer cells, including leukemia, melanoma, osteosarcoma, and small-cell lung cancers, and it can induce apoptosis alone or in combination with other antitumor agents, e.g., cisplatin, doxorubicin, vincristine, methotrexate, and temozolomide [235,236]. This evidence concerns the gene HPGDS and cancer.
