DL-3-Arsonoalanine has been synthesized by the Strecker synthesis from the unstable compound arsonoacetaldehyde. It inactivates pig heart cytosolic aspartate aminotransferase and inhibits aspartate ammonia-lyase by competing with aspartate (Ki/Km 0.23). The fumarate analogue (E)-3-arsonoacrylic acid and the malate analogue (RS)-3-arsonolactate also inhibit fumarate hydratase, competing with fumarate (Ki/Km 1.8) and malate (Ki/Km 1.6) respectively. Attempted non-enzymic transamination of 3-arsonoalanine gave elimination of arsenite, in contrast with the transamination of 3-phosphonoalanine, which is either successful or leads to loss of phosphate.
