AN2898 (5-(3,4-dicyanophenoxy)-1-hydroxy -1,3-dihydro-2,1-benzoxaborole)  is a broad spectrum anti-inflammatory compound currently in development for the topical treatment of plaque and atopic psoriasis.

AN2898 inhibited phosphodiesterase 4 (PDE4) enzyme activity (IC50 0.060 μM) and the release of multiple cytokines including TNF-α (IC50 0.16 μM) from peripheral blood mononuclear cells (hPBMCs) stimulated by lipopolysaccharide (LPS) or phytohemag- glutinin.

Further, AN2898 was also found to inhibit IL-23 release (IC50 1.0 μM) from THP-1 cells stimulated by LPS and IFN-γ. Investigation of the structure-activity relation-ship around this compound was reported to identify a more potent dual TNF-α/IL-23 inhibitor
