Azathioprine is an imidazole derivative of purine that functions to decompose to purine in the body. The mechanism of its immune action is the same as that of purines, that is, it has purine antagonism. Since purine substances are required for the proliferation of immunocompetent cells after antigen stimulation, purine antagonism at this time can inhibit the synthesis of DNA, RNA, and protein, thereby inhibiting Proliferation of lymphocytes, ie, the prevention of transformation of antigen-sensitive lymphocytes into immune mother cells, produces an immune effect.

It is also widely used in autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, active chronic hepatitis, ulcerative colitis, myasthenia gravis, and scleroderma. For chronic nephritic and nephrotic syndrome, the efficacy seems to be inferior to cyclophosphamide.
