Product Description
Physiologically active metabolite of the immunosuppressive drug leflunomide (Prod. No. ALX-430-095). Inhibits the activity of dihydrorotate dehydrogenase and of protein tyrosine kinases. Blocks TNF-mediated NF-κB activation in a dose- and time-dependent manner. Also inhibits the activity of cyclooxygenase-2 (COX-2) in vitro and in vivo.
