Product Overview
AN-2728 is an inhibitor of PDE4 with IC50 value of 0.49 μM. PDE4 is a phosphodiesterase and plays an important role in the chronic inflammation associated with psoriasis and atopic dermatitis. AN-2728 is a boron-containing, anti-inflammatory, topically administered compound that inhibits PDE4 activity and suppresses the release of TNF-α, IL-23, IL-12 and other cytokines. In cell based assays, AN-2728 inhibited cytokine release of TNF-α, IL-2, IFN-γ, IL-5 and IL-10 with IC50 values of 0.54, 0.61, 0.83, 2.4 and 5.3 μM, respectively. AN-2728 was well tolerated and had good therapeutic potential. AN-2728 is now in clinical development for the treatment of psoriasis and atopic dermatitis.
