MAPK Kinase Inhibitor - MEK1 and MEK2 Inhibitor

PD98059 is a potent and selective inhibitor of MAP kinase kinases (MAPKK), MEK1 and MEK2 [1]. It binds to the inactive form of MAPKK and prevents activation by upstream activators such as c-Raf. Thus, PD98059 can be used to study the role of MAPKK signaling in different immune responses. For example, PD98059 can inhibit the lipopolysaccharide (LPS)-induced production of cytokines such as TNF-α [2, 3].
