synthesis and evaluation of imidazo[4,5-b]pyridines as inhibitors of B-Raf kinase. These compounds bind in a DFG-in, αC-helix out conformation of B-Raf, which is a binding mode associated with significant kinase selectivity. Structure–activity relationship studies involved optimization of the ATP-cleft binding region of these molecules, and led to compound 23, an inhibitor with excellent enzyme/cell
这封信详细介绍了咪唑并[4,5- b ]吡啶类作为B-Raf激酶抑制剂的合成和评价。这些化合物以B-Raf的DFG-in,αC-螺旋构象结合,这是与显着的激酶选择性相关的结合模式。结构与活性之间的关系研究涉及优化这些分子的ATP裂隙结合区,并产生化合物23,这是一种具有出色的酶/细胞效能和激酶选择性的抑制剂。
