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.
