Metabolite Identification
Common NameS-methylazathioprine
DescriptionS-methylazathioprine is a metabolite of azathioprine. Azathioprine is a purine analogue immunosuppressive drug. It is used to prevent rejection following organ transplantation, and to treat a vast array of autoimmune diseases, including rheumatoid arthritis, pemphigus, inflammatory bowel disease, multiple sclerosis, autoimmune hepatitis, atopic dermatitis, myasthenia gravis, neuromyelitis optica or Devic's disease, restrictive lung disease, and others.
