Description

Application

α-Cyano-4-hydroxycinnamic acid has been used to block monocarboxylate transporters.

α-Cyano-4-hydroxycinnamic acid is a useful hydrophobic matrix solution for matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. Antibiotics, peptide nucleic acids (a new class of DNA mimics), and proteins with masses as high as 66,000 Da have been successfully analyzed by using this as a matrix solution.

Biochem/physiol Actions

α-Cyano-4-hydroxycinnamic acid acts as a specific inhibitor of monocarboxylic acid transport, including lactate and pyruvate transport. It is also reported to block β-cell apical anion exchange (IC₅₀ of 2.4 mM).
