Biochem/physiol Actions

Pyr10 is a novel, selective inhibitor of the transient receptor potential channel TRPC3. Pyr10 blocks carbachol-induced calcium entry into TRPC3-transfected HEK293 cells (IC50 = 0.72 μM), with significantly lower activity against STIM1/Orai1 mediated release of calcium from endoplasmic reticulum (store operated calcium entry) in BRL-2H3 cells (IC50 = 13.08 μM).

Oxidative stress and reactive oxygen species (ROS) generation can be influenced by G-protein coupled receptor (GPCR)-mediated regulation of intracellular Ca2+ ([Ca2+]i) signaling. ROS production are much higher in proximal tubular (PT) cells; in addition, the lack of antioxidants enhances the
