Mechanism of action

6MP is converted intracellularly to active metabolites that interfere with purine metabolism and DNA synthesis, leading to reduced proliferation of lymphocytes and other rapidly dividing cells. The drug is used in individualized dosing regimens, likely guided by thiopurine methyltransferase (TPMT) genotyping or metabolite monitoring to optimize efficacy while minimizing toxicity.
