NJK14047 is a drug which acts as a selective inhibitor of the enzyme p38 mitogen-activated protein kinase (p38 MAPK). It has antiviral and antiinflammatory effects and was originally developed as a potential treatment for inflammatory lung conditions such as influenza. Subsequent research has also shown promise for various other conditions in which inflammation plays a role, including Alzheimer's disease, asthma, arthritis and psoriasis.
