Mecanismo de acción (Mechanism of Action)

Targets/IC₅₀/Ki	dihydroorotate dehydrogenase
In vitro	Teriflunomide primarily acts as an inhibitor of dihydroorotate dehydrogenase (DHODH), a key mitochondrial enzyme involved in the de novo synthesis of pyrimidines in rapidly proliferating cells. By reducing the activity of high-avidity proliferating T lymphocytes and B lymphocytes, teriflunomide likely attenuates the inflammatory response to autoantigens in MS. Thus, teriflunomide can be considered a cytostatic rather than a cytotoxic drug to leukocytes.
In vivo	Teriflunomide has demonstrated beneficial effects in two independent animal models of demyelinating disease. In the dark agouti rat model of experimental autoimmune encephalitis (EAE), teriflunomide administration results in clinical, histopathological, and electrophysiological evidence of efficacy both as a prophylactic and therapeutic agent. Similarly, in the female Lewis rat model of EAE, teriflunomide administration results in beneficial prophylactic and therapeutic clinical effects, with a delay in disease onset and symptom severity.

Preguntas frecuentes (Frequently Asked Questions)

Pregunta 1:
I am planning to use it (S4169) in my in vivo protocol, but I cannot get a homogeneous solution. Could you please provide me with some guidance?

Respuesta:
This compound is an oral clinical medicine. For oral administration suspension is fine. In paper http://www.pnas.org/content/108/44/18067.full, they also prepared the stock by DMSO and then diluted it into 0.9% sterile saline for animial study.
