Description

Application

U-73122 hydrate has been used for studying the role of phospholipase C (PLC) signaling in modulating epithelial Na⁺ channel (ENaC) function in gerbil Reissner′s membranes (RMs)[1]. U-73122 has also been used to study local calcium responses in human umbilical vein endothelial cells (HUVECs)[2].

Biochem/physiol Actions

Inhibits the hydrolysis of PPI to IP₃, which leads to a decrease in cytosolic free calcium. Inhibits the coupling of G protein-phospholipase C activation, while remaining unaffected by production of cAMP.
