these inhibitors inhibit histone H3 citrullination in HEK293TPAD1 cells and mouse zygotes with excellent potency. Based on this scaffold, we also developed a PAD1-selective activity-based probe that shows remarkable cellular efficacy and proteome selectivity. Based on their potency and selectivity we expect that 1 and 19 will be widely used chemical tools to understand PAD1 biology.
蛋白质精氨酸脱亚氨酶(PADs)水解精氨酸的侧链形成瓜氨酸。PAD异常活动与类风湿性关节炎,多发性硬化症,狼疮和某些癌症有关。这些病理将PAD确定为治疗靶标,并且多种PAD抑制剂是已知的。在这里,我们描述了第一个高效的PAD1选择性抑制剂(1和19)。详细的结构活性关系表明它们的效能和选择性是由于与PAD1形成了卤素键。重要的是,这些抑制剂以优异的效力抑制HEK293TPAD1细胞和小鼠受精卵中的组蛋白H3瓜氨酸化。基于此支架,我们还开发了基于PAD1选择性活性的探针,该探针显示出显着的细胞功效和蛋白质组选择性。
