Immunopharmacology Comments
PDE4 is a drug target, whose inhibition has anti-inflammatory action. PDE4 inhibitors have already entered clinical use, being employed in the treatment of inflammatory skin conditions such as psoriatic arthritis (apremilast) and atopic dermatitis (crisaborole). PDE4B is the predominant phosphodiesterase subtype in monocytes and neutrophils and this is thought to be the sub-type central to inflammatory action of phosphodiesterases [15]. The development compound difamilast is reported to show selectivity for this PDE4 isoform [3].
