[C][C][C][Branch1][C][C][S][S][C][=N][C][=C][N][Ring1][Branch1]"}, {"from": "gpt", "value": "The molecule is a small-molecule inhibitor of Trx-1 (thioredoxin-1), stimulates apoptosis, down-regulates HIF-1\u03b1 and vascular endothelial growth factor (VEGF) and inhibits tumor growth in animal models. Since high levels of Trx-1 have been associated with colorectal, gastric and lung cancers, PX-12 is indicated as a potential cancer treatment in combination with chemotherapy for  patients with advanced metastatic cancer. Initial trials correlated doses of Px-12 with increased patient survival."}]
