stacking interactions) with structurally simplified hydrophobic cage structures with much reduced conformational flexibility and rotational freedom. The binding mode of the compounds was elucidated by X-ray crystallography, and the compounds showed excellent oral bioavailability and clearance in rat PK studies.
描述了新的Bcl-2蛋白-蛋白相互作用拮抗剂的发现。我们用结构简化的疏水笼结构替换了ABT737的北部片段(pi-pi堆积相互作用),并降低了构象柔韧性和旋转自由度。通过X射线晶体学阐明了化合物的结合模式,并且在大鼠PK研究中化合物显示出优异的口服生物利用度和清除率。
