Common Name | 6-Methylmercaptopurine |
---|
Description | 6-Methylmercaptopurine, also known as thiopurine S-methylether, belongs to the class of organic compounds known as 6-thiopurines. 6-thiopurines are compounds containing a purine that carries a thiol group at the 6-position. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. It is a thiopurine. 6-Methylmercaptopurine is a metabolite of mercaptopurine. 6-Methylmercaptopurine is a strong basic compound (based on its pKa). Mercaptopurine (also called 6-mercaptopurine, 6-MP or its brand name Purinethol) is an immunosuppressive drug. 6-Methylmercaptopurine exists in all living organisms, ranging from bacteria to humans. S-adenosylhomocysteine and 6-methylmercaptopurine can be biosynthesized from mercaptopurine and S-adenosylmethionine through the action of the enzyme thiopurine S-methyltransferase. In humans, 6-methylmercaptopurine is involved in mercaptopurine metabolism pathway. |
