alpha-Cyano-3-hydroxycinnamic acid is a mitochondrial matrix analog that has been shown to inhibit the uptake of carnitine, glutamate, and branched-chain amino acids. This compound also inhibits the activity of glyceraldehyde-3-phosphate dehydrogenase and dodecyl CoA dehydrogenase, which are enzymes involved in the production of cellular energy. alpha-Cyano-3-hydroxycinnamic acid also inhibits the synthesis of mitochondrial DNA and RNA. The compound binds to the enzyme succinate dehydrogenase, inhibiting its function. This inhibition leads to a decrease in cellular energy production and an increase in oxidative stress.

a-Cyano-4-hydroxycinnamic acid is a high quality chemical that is useful as a reagent, intermediate and building block. This compound has been used in the synthesis of various complex compounds including the fine chemicals, useful scaffolds and research chemicals. The versatility of this compound makes it an important reaction component for many reactions.
