Application

XMD8-92 has been used as a specific extracellular signal regulated kinase 5 (ERK5) inhibitor in human umbilical vein endothelial cells (HUVECs) culture.

Biochem/physiol Actions

XMD8-92 is a potent and selective inhibitor of BMK1/ERK5/MAPK7 and DCAMKL1 (DCLK1), kinases implicated in tumorigenesis. XMD8-92 has a Kd of 80 nM for ERK5 and a Kd of 97 nM for DCAMKL1. The next closest targets are DCAMKL2 (190 nM), TNK1 (890 nM), and PLK4 (600 nM). Through inhibition of BMK1 activity, XMD8-92 blocked tumor cell proliferation in vitro in a wide variety of cancer cell lines and significantly inhibited tumor growth in vivo by 95% in mouse studies. XMD8-92 inhibited AsPC-1 human pancreatic cancer cell proliferation and pancreatic tumor xenograft growth via a DCLK1-dependent mechanism.

Other Notes

XMD8-92 has been expertly reviewed and recommended by the Chemical Probes Portal. For more information, please visit the XMD8-92 probe summary on the Chemical Probes Portal website.

Malignant mesothelioma is an aggressive cancer in desperate need of treatment. We have previously shown that extracellular signaling regulated kinase 5 (ERK5) plays an important role in mesothelioma pathogenesis using ERK5 silenced human mesothelioma cells exhibiting significantly reduced tumor growth

Macrophages are highly plastic cells, responding to diverse environmental stimuli to acquire different functional phenotypes. Signaling through MAPKs has been reported to regulate the differentiation of macrophages, but the role of ERK5 in IL-4-mediated M2 macrophage differentiation is still unclear.

The skeletal muscle consists of contractile myofibers and plays essential roles for maintenance of body posture, movement, and metabolic regulation. During the development and regeneration of the skeletal muscle tissue, the myoblasts fuse into multinucleated myotubes that subsequently form myofibers.
