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.

This paper describes a specific and sensitive reversed-phase HPLC assay for the measurement of 6-methylthioguanine (methyl-TG) and methyl-TG nucleotides (methyl-TGNs) in red blood cells (RBCs), which is suitable for routine clinical use. Briefly, an ethyl acetate extract of RBCs is

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

A reversed phase high performance liquid chromatographic procedure was developed to quantify 6-thioguanine, 6-mercaptopurine, methylthioguanine, and methylmercaptopurine in red blood cells. The free base of each thiopurine was liberated from the respective nucleoside and nucleotide moiety by acid hydrolysis, which
