摘要:
As part of our research effort to discover B-Raf kinase inhibitors, we prepared a series of C-3 substituted N-(3-(pyrazolo[1,5-a]pyrimidin-7-yl)phenyl)-3-(trifluoromethyl)benzamides. X-ray crystallography studies revealed that one of the more potent inhibitors (10n) bound to B-Raf kinase without forming a hinge-binding hydrogen bond. With basicamine residues appended to C-3 aryl residues, cellular activity and solubility were enhanced over previously described compounds of this class. (C) 2009 Elsevier Ltd. All rights reserved.
