Composition
Mercaptopurinum 20 mg/ml
ATC Code
L01BB02
Source
URPL
Pharmacotherapeutic group: antineoplastic agents, antimetabolites, purine analogues, ATC Code: L01BB02
Mechanism of action
Mercaptopurine monohydrate is sulphydryl analogue of the purine bases, adenine and hypoxanthine and acts as a cytotoxic antimetabolite.
Mercaptopurine monohydrateis an inactive pro-drug which acts as a purine antagonist but requires cellular uptake and intracellular anabolism to thioguanine nucleotides for cytotoxicity. The mercaptopurine monohydrate 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.
Cross-resistance usually exists between mercaptopurine monohydrate and 6-thioguanine.
Pharmacodynamic effects
The cytotoxic effect of mercaptopurine monohydrate can be related to the levels of red blood cell mercaptopurine monohydrate derived thioguanine nucleotides, but not to the plasma mercaptopurine monohydrate concentration.
⚠️ Warnings
