Biphenyl amide p38 kinase inhibitors 4: DFG-in and DFG-out binding modes.
R.M.Angell, T.D.Angell, P.Bamborough, M.J.Bamford, C.W.Chung, S.G.Cockerill, S.S.Flack, K.L.Jones, D.I.Laine, T.Longstaff, S.Ludbrook, R.Pearson, K.J.Smith, P.A.Smee, D.O.Somers, A.L.Walker.
The biphenyl amides (BPAs) are a series of p38alpha MAP kinase inhibitors. Compounds are able to bind to the kinase in either the DFG-in or DFG-out conformation, depending on substituents. X-ray, binding, kinetic and cellular data are shown, providing the most detailed comparison to date between potent compounds from the same chemical series that bind to different p38alpha conformations. DFG-out-binding compounds could be made more potent than DFG-in-binding compounds by increasing their size. Unexpectedly, compounds that bound to the DGF-out conformation showed diminished selectivity. The kinetics of binding to the isolated enzyme and the effects of compounds on cells were largely unaffected by the kinase conformation bound.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
