| Abstract: | 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. |
