A complex of polyethylene glycol conjugated with L-asparaginase. Asparaginase hydrolyzes L-asparagine to L-aspartic acid and ammonia, thereby depleting these … [Read more...]


A non-essential amino acid. In hepatocytes, L-citrulline is synthesized in the urea cycle by the addition of carbon dioxide and ammonia to ornithine. … [Read more...]


An enzyme isolated from the bacterium Escherichia coli or the bacterium Erwinia carotovora with antileukemic activity. Asparaginase hydrolyzes L-asparagine to … [Read more...]

hydrazine sulfate

The synthetic sulfate salt of hydrazine, a derivative of ammonia. Hydrazine inhibits the enzyme phosphoenol pyruvate carboxykinase, thereby blocking … [Read more...]


A nonessential amino acid. Glutamine can donate the ammonia on its side chain to the formation of urea (for eventual excretion by the kidneys) and to purines … [Read more...]


A second-generation platinum compound with a broad spectrum of antineoplastic properties. Carboplatin contains a platinum atom complexed with two ammonia … [Read more...]


An enzyme isolated from the bacterium Erwinia chrysanthemi (E. carotovora). Asparagine is critical to protein synthesis in leukemic cells, which cannot … [Read more...]
