PX-12 (PX12) (1-methylpropyl 2-imidazolyl disulfide) is a small-molecule inhibitor of Trx-1 (thioredoxin-1), stimulates apoptosis, down-regulates HIF-1α 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.

TRPV2-selective blocker 1 (compound IV2-1) is a selective inhibitor of the TRPV2 channel, with an IC50 value of 6.3 μM, specifically targeting the TRPV2 channel without affecting TRPV1, TRPV3, or TRPV4 channels, and effectively suppresses TRPV2-mediated calcium influx in macrophages, inhibiting their phagocytic activity [1].
