An improved fluorogenic substrate for the detection of alkaline phosphatase activity
摘要:
We designed a new alkaline phosphatase (ALP)-sensitive fluorogenic probe in which a self-immolative spacer group, p-hydroxybenzyl alcohol, is linked to a profluorogenic compound to improve substrate specificity. Enzymatic hydrolysis converts the fluorogenic substrate 1 to a highly fluorescent reporter 3, thus allowing for the fast and quantitative analysis of ALP activity with greatly increased affinity for the enzyme.

affairs: Phosphoester substrates that release electrophilic quinone‐methides were applied as activity‐basedprobes in three phosphotriesterases that differ in mechanism and level of activity. Their substrates′ reactivity, and mode of labeling, were systematically investigated with the aim of achieving specific cislabeling rather than trans.

. The fluorescent probe capable of detecting ALP can selectively detect ALP only quickly and accurately. In addition, the fluorescent probe allows monitoring of a biological phenomenon occurring in cells and tissues through noninvasive in-vivo imaging and during the early osteogenic differentiation in real time.
