where the polar 5-nitrile group was shown by crystallography to bind in the hydrophobic pocket of DOT1L. In addition, we show that a polar nitrile group can be used as a non-traditional replacement for heavy halogen atoms.
公开了许多新的核苷衍生物作为DOT1L活性的抑制剂。SARs证实,可以通过在5位(5、6、12)掺入极性基团和小的杂环或通过使用其他含氮碱基(18)来实现DOT1L抑制。根据这些结果,CN-SAH(19)被确定为DOT1L活性的有效和选择性抑制剂,其中结晶晶体显示极性5腈基结合在DOT1L的疏水口袋中。此外,我们表明极性腈基可以用作重卤素原子的非传统替代物。
