The thiopurines are prodrugs which have been transformed by a number of enzymes into thioguanine nucleotides (TGN). TGNs are then incorporated into DNA. Inactivation of TGN takes place by two key mechanisms: oxidation by xanthine oxidase and methylation by TPMT. Xanthine oxidase activity is negligible in hematopoetic tissues, so these cells rely upon TPMT for TGN inactivation.
Pharmacogenomics is the use of genetic information to guideline the choice of drug and dose on an individual foundation. It intends to recognize people who are either extra probable or less likely to answer a drug, and also those who need altered dose of certain drugs. Try is produced to outline the genetic foundation of a person’s profile of drug reaction and to predict the ideal procedure option for him/her.
