explored to select a potentially new biasing binding element for the zinc in HDAC catalytic site. All compounds were evaluated for their in vitro inhibitory activity against the 11 human HDACs isoforms. After identification of a “hit” molecule, a programmed variation at the cap group and at the linker was carried out in order to increase HDAC inhibition and/or paralogue selectivity. Some of the new
探索了几种以SAHA样结构为特征的含肟分子,为HDAC催化位点的锌选择潜在的新偏置结合元素。评价所有化合物对11种人类HDAC同工型的体外抑制活性。鉴定“命中”分子后,在帽基团和接头处进行了程序设计的变异,以增加HDAC抑制和/或旁系同源物的选择性。一些新衍生物显示出对许多HDAC同工型的增强活性,即使它们的总体活性范围仍远未达到SAHA报道的抑制值。而且,与报道的异羟肟酸类似物不同,新的α-肟酰胺衍生物不在I类和II类HDAC之间进行选择。而是针对每个类别的特定同工型。这些矛盾的结果最终通过计算辅助SAR得以合理化,这使我们有机会了解肟衍生物如何与催化部位相互作用并证明观察到的活性分布合理。
