The discovery of carboline analogs as potent MAPKAP-K2 inhibitors

Bioorg Med Chem Lett. 2007 Aug 15;17(16):4664-9. doi: 10.1016/j.bmcl.2007.05.101. Epub 2007 Jun 7.


The discovery of a series of potent, carboline-based MK2 inhibitors is described. These compounds inhibit MK2 with IC50s as low as 10 nM, as measured in a DELFIA assay. An X-ray crystal structure reveals that they bind in a region near the p-loop and the hinge region of MK2a.
