Inhibitor Comments
We have assigned the IC50 value for revamilast obtained from patent WO2006064355A2 to PDE4A, but the assay description in the patent document does not specify the isozyme tested, or the source of the PDE4 used [6].
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).

COVID-19: The anti-inflammatory effect of PDE4 inhibition has been suggested as being a mechanism that could be applied to down-modulate the hyper-inflammation that can arise from SARS-CoV-2 infection [4-5].
