The synthesis of a chromogenic substrate for mammalian PI-PLC, D,L-myo
-inositol 4,5-bis(dihydrogen phosphate) 1-(4-nitrophenyl hydrogen phos
phate) tetrasodium salt (13), is described. Phosphoinositol bisphospha
te 13 (NPIP-P-2) is shown to be a substrate for human PI-PLC delta(1)
in a nonradioactive, continuous assay. (C) 1997 Elsevier Science Ltd.
