α-Cyano-4-hydroxycinnamic acid

α-Cyano-4-hydroxycinnamic acid (α-Cyano-4-hydroxycinnamate) is a potent and non-competitive inhibitor of monocarboxylate transporters (MCTs). α-Cyano-4-hydroxycinnamic acid inhibits mitochondrial pyruvate transporter with a Ki of 6.3 μM. α-Cyano-4-hydroxycinnamic acid is used as a matrix to facilitate peptide ionization in matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry applications[1][2].
