Interleukin-1 receptor antagonists

These agents have anti-inflammatory characteristics.

Leflunomide (Arava)

Isoxazole immunomodulatory agent with anti-inflammatory characteristics. Mechanism of action is through the inhibition of dihydroorotate dehydrogenase, which leads to a decrease in proliferative activity.

Although not entirely elucidated, it is thought to inhibit de novo pyrimidine synthesis. It inhibits proliferation of immune cells.
