Definition
-tsukuba macolide immunosupressent
-similar to cyclopsporin (calcineurin-IL2)
Term
azothioprine
Definition
-inhibits purine synthesis->slows DNA synthesis (B and T cells)
-pro-drug-->6-merpcaptopurine
-bone marrow toxicity
-teratogenic
-metabolized by TPMT-polymorphisms
(also metabolizes 6-thioguanine)
TPMT deficient-->leads to hematotoxicity
