iGP-1 (27031-00-1) is a potent and cell permeable inhibitor of mitochondrial glycerol-3-phosphate dehydrogenase (mGPDH), IC50=6.3 μM, that is selective over the cytosolic enzyme1. It does not block pyruvate uptake into cells or mitochondria and has no direct effect on glycolysis in synaptosomes. This novel inhibitor is a unique tool which may be used to investigate the role of glycerol-3-phosphate metabolism in isolated and intact systems.1
