WebJul 1, 1994 · A series of nitrocoumarin and nitrochromene derivatives have been prepared and shown to inhibit the phosphatidylinositol-specific phospholipase C (PLC) (IC50 < 10 micrograms/mL) isolated from human melanoma. The inhibition of PLC by nitrocoumarin 4a was time-dependent and irreversible. Phospholipase C (PLC) is a class of membrane-associated enzymes that cleave phospholipids just before the phosphate group (see figure). It is most commonly taken to be synonymous with the human forms of this enzyme, which play an important role in eukaryotic cell physiology, in particular signal … See more Mammalian variants The extensive number of functions exerted by the PLC reaction requires that it be strictly regulated and able to respond to multiple extra- and intracellular inputs with appropriate kinetics. … See more Activation Receptors that activate this pathway are mainly G protein-coupled receptors coupled to the See more PLC cleaves the phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) into diacyl glycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). Thus PLC has a profound impact on the depletion of PIP2, which acts as a membrane anchor or allosteric regulator … See more In mammals, PLCs share a conserved core structure and differ in other domains specific for each family. The core enzyme includes a split triosephosphate isomerase (TIM) barrel See more The primary catalyzed reaction of PLC occurs on an insoluble substrate at a lipid-water interface. The residues in the active site are conserved in all PLC isotypes. In animals, PLC selectively catalyzes the hydrolysis of the phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) See more • Glycosylphosphatidylinositol diacylglycerol-lyase EC 4.6.1.14 A trypanosomal enzyme. • Phosphatidylinositol diacylglycerol-lyase EC See more
