    适合片段筛选的比色测定揭示了奥罗恩和查尔酮作为新的精氨酸酶抑制剂
    摘要:
    精氨酸酶是一种难以靶向的金属酶,与多种疾病有关,包括癌症、传染病和心血管疾病。尽管存在医学需求,但现有抑制剂的结构多样性有限,主要由氨基酸及其衍生物组成。对创新精氨酸酶抑制剂的探索现已扩展到筛选方法。由于精氨酸酶的活性位点小而窄,筛选必须满足基于片段的筛选标准。然而,片段的结合能力有限,需要在高浓度下工作,这增加了干扰和误报的风险。在这项研究中,我们研究了三种比色测定法,并根据干扰选择了一种在这些具有挑战性的条件下进行筛选。随后对金属螯合剂片段库的筛选进行调整和应用,鉴定出四种具有中等活性的化合物。对其中一个热门化合物的一系列化合物进行合成和评估,得到化合物21a ,其 IC 50值为 91.1 μM,接近参考化合物白皮杉醇。最后,分子模型支持金酮和查耳酮与精氨酸酶活性位点的潜在结合,表明它们是开发新型精氨酸酶抑制剂的新候选者。
