This invention provides new methods for detecting enzyme activity using enzyme substrates comprising an enzyme cleavable portion and a chromogenic portion. The enzyme cleavable portion is a &bgr;-D-ribofuranosyl group and the chromogenic portion forms a detectable indicator following enzyme cleavage. In one aspect of this invention the chromogenic &bgr;-D-ribofuranoside substrate forms a coloured substantially non-diffusable indicator. A second aspect of this invention provides novel chromogenic &bgr;-D-ribofuranosides.
本发明提供了使用酶底物检测酶活性的新方法,酶底物包括酶可裂解部分和发色部分。酶可裂解部分是一个 &bgr;-D-呋喃核糖基团,发色部分在酶裂解后形成可检测的指示剂。在本发明的一个方面中,发色性 &bgr;-D-ribofuranoside 底物形成一种有色的基本上不可扩散的指示剂。本发明的第二个方面提供了新型的发色性&bgr;-D-呋喃核苷。
