Prostaglandin H2 (PGH2) is an endothelium-derived contracting factor. Prostaglandin H2 can cause vasoconstriction. Prostaglandin H2 is the common precursor of all PGs and is produced by several cells that express cyclooxygen-ases. Prostaglandin H2 can activate PGD2 receptors CRTH2 and DP via interacting directly with the receptors and/or by giving rise to PGD2 after catalytic conversion by plasma proteins. Prostaglandin H2 can induce eosinophils migration and inhibit platelet aggregation. Prostaglandin H2 can accelerate the formation of dimers and higher oligomers of amyloid β1-42. Prostaglandin H2 can be used for the researches of inflammation and neurological disease, such as Alzheimer disease .

UM4118 is a potent copper-selective non-genotoxic copper ionophore that induces cuproptosis in acute myeloid leukemia cells. UM4118 exhibits stronger activity against SF3B1G12C mutant acute myeloid leukemia cells. UM4118 transports extracellular copper into cells, elevates intracellular and mitochondrial copper levels, and triggers lipoylated DLAT aggregation, proteotoxic stress, iron-sulfur cluster protein depletion, reduced lipoylated protein levels, and maximal mitochondrial respiratory damage. UM4118 cytotoxicity can be enhanced by supplementation with extracellular copper, abolished by copper chelation, and shows synthetic lethal effects in the absence of iron-sulfur cluster biosynthesis/transport genes.
