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.

Various derivatives of 2-amino-6- methylthiopurine with substituents at the 6-position of purine were tested for their abilities to displace [3H]diazepam binding to rat brain membranes. The potency was dependent on the carbon chain-length in the 6-position of purine. Among the

It is proposed here that the delayed cytotoxicity of thioguanine involves the postreplicative DNA mismatch repair system. After incorporation into DNA, the thioguanine is chemically methylated by S-adenosylmethionine to form S6-methylthioguanine. During DNA replication, the S6-methylthioguanine directs incorporation of either

We have compared fifteen synthetic purines and purine nucleosides on their ability to displace [3H]diazepam binding to rat brain membranes. Among these analogs, 6-methylthioguanine was found to be most potent, inhibiting competitively the specific binding of [3H]diazepam with a Ki
