Active ingredients

The drug LEUKERIN contains one active pharmaceutical ingredient (API):

1 Mercaptopurine UNII E7WED276I5 - MERCAPTOPURINE
Mercaptopurine is an inactive pro-drug which acts as a purine antagonist but requires cellular uptake and intracellular anabolism to thioguanine nucleotides for cytotoxicity. The mercaptopurine metabolites inhibit de novo purine synthesis and purine nucleotide interconversions. The thioguanine nucleotides are also incorporated into nucleic acids and this contributes to the cytotoxic effects of the active substance. Read about Mercaptopurine
