Coumalic acid
Coumalic acid is an inhibitor of human carbonic anhydrase (hCA) (KI = 0.073 μM for hCA IX; KI = 0.083 μM for hCA XII). Coumalic acid is a valuable platform compound which can be prepared from malic acid. Coumalic acid can be used in the flavorings, fragrances and cosmetics industries, as polymer components, and pharmaceutical scaffolds. Coumalic acid displays antibronchial and antimalarial activity[1][2].
