6-Methylmercaptopurine

6-Methylmercaptopurine (6-MMP) is a metabolite of the purine synthesis and interconversion inhibitor 6-mercaptopurine (6-MP, Cay-23675). It is formed from 6-MP via methylation by thiopurine S-methyltransferase. Levels of 6-MMP are increased in patients with altered thiopurine metabolism and associated with therapeutic resistance to 6-MP.Formal Name: 6-(methylthio)-9H-purine. CAS Number: 50-66-8.
