Application

7-Hydroxycoumarinyl-4-acetic acid was used in the synthesis of novel and specific enzyme substrates for Maroteaux-Lamy (MPS VI) and Morquio A (MPS IVA) diseases. It was also employed as ionic liquid matrice for MALDI-TOF MS of proteins, peptides and carbohydrates.

The fluorescence-based long-chain fatty acid probe BSA-HCA (bovine serum albumin labeled with 7-hydroxycoumarin-4-acetic acid) is shown to respond to binding of long-chain acyl-CoA thioesters by quenching of the 450 nm fluorescence emission. As determined by spectrofluorometric titration, binding affinities for

A covalent complex between bovine serum albumin and 7-hydroxycoumarin-4-acetic acid (BSA-HCA) shows a strong fluorescence band at lambdamax = 450 nm upon excitation at 375 nm. Quenching of the fluorescence emission accompanies the association of fatty acids (FA) to BSA-HCA
