Dynamic combinatorial chemistry (DCC) is a powerful supramolecular approach for discovering ligands for biomolecules. To date, most, if not all, biologically templated DCC systems employ only a single biomolecule to direct the self‐assembly process. To expand the scope of DCC, herein, a novel multiprotein DCC strategy has been developed that combines the discriminatory power of a zwitterionic “thermal
动态组合化学(DCC)是一种强大的超分子方法,可用于发现生物分子的配体。迄今为止,大多数(如果不是全部)生物模板化DCC系统仅采用单个生物分子来指导自组装过程。为了扩大DCC的范围,本文开发了一种新颖的多蛋白DCC策略,该策略将两性离子“热标签”的辨别能力与差示扫描荧光法的灵敏度相结合。该策略高度敏感,可以区分配体与结构相似的亚家族成员的结合。通过这种策略,有可能同时针对两种临床上重要的表观遗传酶识别亚科选择性探针:FTO(7 ; IC 50 = 2.6μ米)和ALKBH3(8 ; IC 50 = 3.7μ米)。迄今为止,这是亚家族选择性ALKBH3抑制剂的首次报道。原则上,已开发的策略可以适应多种蛋白质;因此,它具有广泛的科学意义。
