Beschreibung
In September 2012, the US FDA approved teriflunomide (also referred
to as HMR-1726) as a therapy for patients with relapsing forms of multiple
sclerosis (MS). Teriflunomide is the second approved oral treatment option
for MS, after Gilenya? which was approved in 2010. Teriflunomide, which is the active metabolite of leflunomide (a marketed
drug for the treatment of rheumatoid and psoriatic arthritis), is a non?competitive and selective inhibitor of dihydroorotate dehydrogenase
(DHODH), the rate-limiting enzyme in the de novo synthesis of pyrimidines.
Although the net effect of inhibition of DHODH by teriflunomide and its
therapeutic effect in MS are not clear, it is hypothesized that by inhibiting de novo pyrimidine synthesis, the effector functions of activated lymphocytes
are suppressed, thus dampening the effect of an overactive immune system.
Chemische Eigenschaften
White Solid
Verwenden
The active metabolite of Leflunomide, a potent disease-modifying antirheumatic drug used in the treatment of rheumatoid arthritis. LEF-M interferes with dendritic cell function.
Definition
ChEBI: An enamide obtained by formal condensation of the carboxy group of (2Z)-2-cyano-3-hydroxybut-2-enoic acid with the anilino group of 4-(trifluoromethyl)aniline. Used for the treatment of relapsing forms of multiple sclerosis and rheumatoid
arthritis.
Allgemeine Beschreibung
Teriflunomide, marketed under the trade name Aubagio, is the active metabolite of leflunomide, an immunosuppressive disease-modifying antirheumatic drug, used in active moderate-to-severe rheumatoid arthritis and psoriatic arthritis. An analytical reference standard for use in LC/MS or GC/MS applications including clinical and diagnostic testing such as therapeutic drug monitoring assays.
