A method of detecting the presence of selected living cells in a sample, comprises the steps of contacting the sample with a substrate compound and monitoring for a signal caused by a metabolic activity of said selected living cells resulting in a release of a signalogenic moiety from the substrate compound. The substrate compound has the formula
wherein X is O or NH, A is H or a first enzymatically hydrolyzable group, B is R3 or CH-Y-D, wherein Y is O or NH and D is H or a second enzymatically hydrolyzable group, R1, R2 and R3 are independently selected inert groups, and Sig-O is a signalogenic moiety that upon release thereof converts to said signalophore.
一种检测样品中是否存在选定活细胞的方法,包括以下步骤:将样品与一种底物化合物接触,并监测由所述选定活细胞的代谢活动导致底物化合物释放信号分子而产生的信号。底物化合物的分子式为
其中 X 是 O 或 NH,A 是 H 或第一可酶水解基团,B 是 R3 或 CH-Y-D,其中 Y 是 O 或 NH,D 是 H 或第二可酶水解基团,R1、R2 和 R3 是独立选择的惰性基团,Sig-O 是信号原分子,释放后转化为所述信号团。
