Roflumilast (APTA 2217) is an orally available, long-acting inhibitor of phosphodiesterase (PDE) type 4 (PDE4), with anti-inflammatory and potential antineoplastic activities. Upon administration, roflumilast and its active metabolite roflumilast N-oxide selectively and competitively bind to and inhibit PDE4, which leads to an increase of both intracellular levels of cyclic-3', 5'-adenosine monophosphate (cAMP) and cAMP-mediated signaling.

LEO-32731 is a bioactive chemical.

ML-030 is a potent and selective inhibitor of PDE4(PDE4A, PDE4A1, PDE4B1, PDE4B2, PDE4C1,and PDE4D2 with IC50 of 6.7 nM, 12.9 nM, 48.2 nM, 37.2 nM, 452 nM and 49.2 nM, respectively)

PDE4-IN-29 (Compound 55) is an orally active and selective inhibitor of PDE4, targeting subtypes such as PDE4A1, PDE4B2, and PDE4D3, with an IC50 value for PDE4D3 of less than 5 nM. It inhibits the degradation of cyclic adenosine monophosphate (cAMP), elevating intracellular cAMP levels and suppressing the release of inflammatory mediators like TNF-α. PDE4-IN-29 holds potential for research in inflammatory diseases such as psoriasis, atopic dermatitis, and chronic obstructive pulmonary disease.
