A cell-permeable piperidinyl-pyridine compound that acts as a selective inhibitor of IKK-2 activity (IC₅₀ = 8.5 and 250 nM for IKK-2 and IKK-1, respectively) with little effect towards IKK-3, Syk, and MKK4 (IC₅₀ >20 µM). Exhibits good aqueous solubility (0.12 mg/ml in pH 7.4 isotonic buffer) and potent activity in various cellular assays in vitro (IC₅₀<150 nM). Shown to be orally bioavailable both in rats and mice (BA = 60% and 16%, respectively) and effectively inhibit arachidonic acid-induced swelling in a murine ear edema model in vivo.
