Description: Teriflunomide, aslo known as A77 1726, is the active metabolite of leflunomide. Teriflunomide is an immunomodulatory drug inhibiting pyrimidine de novo synthesis by blocking the enzyme dihydroorotate dehydrogenase. It is uncertain whether this explains its effect on MS lesions. Teriflunomide inhibits rapidly dividing cells, including activated T cells, which are thought to drive the disease process in MS. It has been found that teriflunomide blocks the transcription factor NF-κB. The drug was approved by the FDA on September 13, 2012.
