6-Methylthiopurine 5'-monophosphate ribonucleotide
6-Methylthiopurine 5-monophosphate ribonucleotide, also known as methylthioinosine-5-monophosphate or meTIMP, is a metabolite of mercaptopurine. Mercaptopurine (also called 6-mercaptopurine, 6-MP, or its brand name Purinethol) is an immunosuppressive drug. Mercaptopurine is in the thiopurine and antimetabolite family of medications (Wikipedia). MeTIMP produced from 6-thioinosine monophosphate (6-TIMP) by thiopurine methyltransferase (TPMT) is an active metabolite that can inhibit de novo purine biosynthesis. High concentration of meTIMP has been related to hepatotoxicity and myelotoxicity (PMID: 21311411).
