building blocks for covalently binding ligands. Six reactive groups with modulated electrophilicity were combined with 11 nonreactive moieties, resulting in a small combinatorial library of 72 fragment-like compounds. These compounds were screened against a group of 11 enzyme targets to assess their selectivity and their potential for promiscuous binding to proteins. The assay results showed a considerably
共价配体-靶标相互作用提供了显着的药理优势。然而,必须使通常具有亲电性质的反应性基团的脱靶反应性最小化,并且不可逆抑制剂的选择性是至关重要的要求。因此,我们进行了系统的研究,以确定可以用作共价结合配体构建基的几个亲电基团的选择性。六个具有亲电性调节基团的反应性基团与11个非反应性基团结合在一起,形成了一个由72个片段状化合物组成的小型组合库。针对一组11个酶靶标筛选了这些化合物,以评估其选择性以及与蛋白质混杂结合的潜力。分析结果显示,混杂程度比最初预期的要低得多,
