Abstract

Inorganic pyrophosphate (PPi) is considered as a diagnostic marker for various diseases such as cancer and vascular calcification. It plays also an important preservative role as an additive E450 in foodstuff. In this work, we describe a novel selective Fe III-salen based probe for PPi, which disassembles in the presence of the target analyte into its molecular blocks, 1,2-propanediamine and 3-chloro-5-formyl-4-hydroxybenzenesulfonic acid. The latter signaling unit leads to a fluorometric response. Compared to a related prototype, the new complex shows a 2.3-times stronger emission at 500 nm and a 155-times better selectivity of PPi over ATP. Importantly, the new probe was successfully applied for detecting E450 in foodstuff.
