  Synthesis and characterization of a novel lysosomotropic enzyme substrate that fluoresces at intracellular pH

  摘要：

  Fluorogenic substrates that can be used to detect the activity of enzymes within intact cells are needed for biochemical investigations of human lysosomal storage disorders and identification of gene transfer recombinants. The first member of a new series of lysosomotropic fluorescent probes has been synthesized and characterized. This compound, O-[4-(1-imidazolyl)butyl]-2,3-dicyano-1,4-hydroquinonyl beta-D-galactopyranoside (Im-DCH-beta-Gal), and its aglycon, Im-DCH, contain an N-alkylimidazole as a lysosomotropic substituent. The concentration of such moderately basic amines within acidic cellular organelles should provide increased specificity toward lysosomal hydrolases. The physiochemical properties of Im-DCH, in particular the intensity of its fluorescence at acidic pH's, make its glycosides well suited for the measurement of enzymatic activity within intact cells.

  Fluorogenic substrates that can be used to detect the activity of enzymes within intact cells are needed for biochemical investigations of human lysosomal storage disorders and identification of gene transfer recombinants. The first member of a new series of lysosomotropic fluorescent probes has been synthesized and characterized. This compound, O-[4-(1-imidazolyl)butyl]-2,3-dicyano-1,4-hydroquinonyl beta-D-galactopyranoside (Im-DCH-beta-Gal), and its aglycon, Im-DCH, contain an N-alkylimidazole as a lysosomotropic substituent. The concentration of such moderately basic amines within acidic cellular organelles should provide increased specificity toward lysosomal hydrolases. The physiochemical properties of Im-DCH, in particular the intensity of its fluorescence at acidic pH's, make its glycosides well suited for the measurement of enzymatic activity within intact cells.
