Application

2-Amino-6-methylmercaptopurine (6-MTG) has been used as a supplement in Dulbecco′s modified Eagles medium (DMEM) medium for the selection of gpt-expressing recombinant virus mCMVhMIEPE-gpt.lacZ (cytomegalovirus major immediate-early promotor-enhancer complex-gpt.lacz). It has also been used as a standard in high performance liquid chromatography (HPLC) to assess the activity of thiopurine methyltransferase (TPMT) enzyme.
2-Amino-6-methylmercaptopurine is a 2-amino-6-alkyldithiopurine that has been used with other 6-position carbon analogues to study brain specific diazepam binding.

Biochem/physiol Actions

2-Amino-6-methylmercaptopurine is synthesized from 6-mercaptopurine by the S methylation activity of thiopurine methyl transferase (TMPT) enzyme.
