Immunopharmacology Comments
As a membrane-bound glycoprotein AOC3 (a.k.a. SSAO, VAP-1) is expressed on the surface of endothelial cells when exposed to inflammatory conditions. It has been noted to mediate binding of lymphocytes to peripheral lymph node vascular endothelial cells, a process required for the recirculation of lymphocytes between blood and tissue. This activity profile has suggested AOC3 as a potential drug target for inflammatory and vascular diseases [10]. The clinical potential of AOC3 inhibitors is reviewed in a patent survey [3] and an Annual Reports in Medicinal Chemistry article [5].

General Comments
AOC3 (VAP-1) is a semicarbazide-sensitive amine oxidase, with substrate specificity which overlaps that of the monoamine oxidases (MAOs). AOC3 catalyzes the oxidative conversion of amines to aldehydes with copper and topaquinone (PubChem CID 12387) acting as cofactors. The enzyme is a membrane-bound glycoprotein. AOC3 is expressed on the surface of endothelial cells when exposed to inflammatory conditions [11] and has been noted to mediate binding of lymphocytes to peripheral lymph node vascular endothelial cells [8-9,12], a process required for the recirculation of lymphocytes between blood and tissue. This activity profile has suggested AOC3 as a potential drug target for inflammatory and vascular diseases. Specific and reversible inhibitors of AOC3 activity are in development [2,7,16], including the small molecule phenelzine and the mAb timolumab.
