The invention provides compounds, compositions, methods, substrates, and kits useful for analyzing the metabolic activity in cells, tissue, and animals and for screening test compounds for their effect on cytochrome P450 activity. In particular, a one-step and two-step methods using luminogenic molecules, e.g. luciferins or coelenterazines, that are cytochrome P450 substrates and that are also bioluminescent enzyme, e.g., luciferase, pro-substrates are provided. The present method further provides a method for stabilizing and prolonging the luminescent signal in a luciferase-based assay using luciferase stabilizing agents such as reversible luciferase inhibitors.
本发明提供了化合物、组合物、方法、基质和工具,用于分析细胞、组织和动物中的代谢活性,并用于筛选测试化合物对细胞色素P450活性的影响。具体而言,提供了一步和两步方法,使用发光分子,例如荧光素或荧光素,它们是细胞色素P450底物,也是生物发光酶,例如荧光素酶,以及前体底物。本方法还提供了一种方法,使用可逆荧光素酶抑制剂等荧光素酶稳定剂稳定和延长荧光素酶基于荧光素的测定中的发光信号。
