DescriptionL-asparagine amidohydrolase from E. coli
Indication/DiseaseTo treat acute lympocytic leukemia and non-Hodgkins lymphoma
PharmacodynamicsIn most patients with acute leukemia, the malignant cells are dependent on an exogenous source of asparagine for survival. Normal cells, however, are able to synthesize asparagine and thus are affected less by the rapid depletion produced by treatment with the enzyme asparaginase. Elspar exploits a metabolic defect in asparagine synthesis of some malignant cells.
Mechanism of ActionAsparaginase converts asparagine to aspartic acid and ammonia. It facilitates production of oxalo-acetate which is needed for general cellular metabolism. Some malignant cells lose the ability to produce asparagine and thus the loss of exogenous sources of asparagine leads to cell death.
