Aplicação

By virtue of its immunosuppressant effects, leflunomide has found use in organ transplantation and treatment of rheumatoid arthritis and other autoimmune diseases.

Ações bioquímicas/fisiológicas

Immunosuppressive; inhibits T and B cell proliferation. Activity is attributed mainly to its metabolite, a malononitrile derivative, which is believed to inhibit dihydroorotate dehydrogenase (in the de novo pyrimidine synthesis pathway) as well as several protein tyrosine kinases.

Leflunomide was first shown to have disease-modifying properties in a rat model of adjuvant-induced arthritis. Leflunomide has been subsequently used with success in several animal models of tissue and organ allograft and of autoimmune disease including collagen- and adjuvant-induced arthritis

Leflunomide is an immunosuppressive drug capable of inhibiting cellular and humoral mediated responses in vivo. The mechanism responsible for suppression of B cell antibody responses in vivo has not been identified. In this study we demonstrate that leflunomide functions to

Biochemical pharmacology, 52(4), 527-534 (1996-08-23)
Previous studies have demonstrated that the active metabolite of leflunomide, A77 1726 [N-(4-trifluoromethylphenyl-2-cyano-3-hydroxycrotoamide)], is capable of inhibiting the activities of tyrosine kinases and dihydroorotate dehydrogenase (DHO-DHase). In the present study, we define the relative contribution of these activities to the

Among all the new immunosuppressive molecules being investigated either preclinically or clinically, four stand out: tacrolimus (FK506), sirolimus (rapamycin), mycophenolate mofetil and leflunomide (and its malononitriloamide analogs). Each drug has distinct mechanisms of immunosuppressive action, and in the past year

Leflunomide has been used off-label in renal transplantation because of the attractive combination of antiviral and immunosuppressive effects. This study intends to review the clinical applications of leflunomide with interest to transplantation. In renal transplantation, particularly in BK nephropathy, the
