Abstract
DL-Hydrazinosuccinic acid was synthesized by the reaction of DL-bromosuccinic acid with hydrazine. The compound strongly inhibited aspartate aminotransferase and gave 50% inhibition at 1.3 μM when added simultaneously with L-aspartate to an assay mixture containing enzyme. Incubation of the enzyme with the compound prior to assay resulted in a much stronger inhibition, which proceeded time-dependently. The inhibition was protectable with L-aspartate and was substantially reversed by dialysis.
