包含锚的药效学搜索,对受体结合贡献高于平均水平的片段,结合一步合成是快速发现新型生物活性分子的有力方法。在这里,我们展示了一条用于快速有效地发现天冬氨酰蛋白酶抑制剂的管道。首先,我们假设肼可能是与活性位点 Asp 羧酸相互作用的多价弹头。我们将肼锚定在多组分反应中,并创建了一个大型的肼衍生物虚拟库,可一步合成获得。接下来,我们对文库进行了基于锚定的药效团筛选,并重新合成了排名靠前的化合物。分子的抑制效力最终通过酶活性测定进行评估,结合模式由几种浸泡的晶体结构证实,支持假设和方法的有效性。本文报道的工具管道对于快速生成除 Asp 蛋白酶之外的受体结合剂具有普遍价值。

Boronicacids are amongst the most useful synthetic intermediates, frequently used by modern drug design. However, their access and fast synthesis of libraries are often problematic. We present a methodology on the synthesis of drug-like scaffolds via IMCRs with unprotected phenylboronic acids. To demonstrate an application of our approach, we also performed one-pot Suzuki couplings on the primary
