metoprine

A diaminopyrimidine folate antagonist with potential antineoplastic activity. Metoprine inhibits dihydrofolate reductase, resulting in decreased cellular folate metabolism and cell growth; it also inhibits histamine-N-methyltransferase, resulting in decreased histamine catabolism. Lipid-soluble metoprine is capable of crossing the blood-brain barrier.
