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).

Exposure of nervous tissue to hypoxia results in interstitial acidification. There is evidence for concomitant decrease in extracellular pH to the increase in tissue lactate. In the present study, we used double-barrelled pH-sensitive microelectrodes to investigate the link between lactate
