Despite the resurging interest in covalent inhibitors, libraries are typically designed with synthon filtered out for reactive functionalities that can engage a target through covalent interactions. Herein, we report the synthesis of two libraries containing Michael acceptors to identify cysteine reactive ligands. We developed a simple procedure to discriminate between covalent and high affinity non-covalent
DNA编码的化学文库越来越多地用于鉴定药物发现或化学生物学的线索。尽管对共价抑制剂的兴趣重新兴起,但通常设计的文库中已过滤出合成素,以实现可通过共价相互作用与靶标结合的反应性功能。在本文中,我们报告了两个包含迈克尔受体以鉴定半胱氨酸反应性配体的文库的合成。我们开发了一种简单的程序,可使用微阵列格式的文库的DNA显示来区分共价和高亲和力非共价抑制剂。该方法已用已知的共价和高亲和力非共价激酶抑制剂进行了验证。文库的筛选显示了MEK2和ERBB2的新型共价抑制剂。
