  摘要：

  乳酸脱氢酶A（LDH-A）催化糖酵解途径中乳酸和丙酮酸的相互转化。癌细胞严重依赖于糖酵解而不是氧化磷酸化来生成ATP，这种现象被称为Warburg效应。因此，对于潜在的癌症治疗而言，小分子对LDH-A的抑制作用是令人关注的。我们描述了通过基于片段的药物发现对LDH-A抑制剂的鉴定和优化。我们应用了基于配体的NMR筛选来鉴定与LDH-A结合的低亲和力片段。解离常数（K d）和酶抑制（IC 50分别通过表面等离振子共振（SPR）和酶法测定片段命中率。通过X射线晶体学研究所选片段的结合模式。片段的生长和连接，然后进行化学优化，产生了纳摩尔浓度的LDH-A抑制剂，该抑制剂表现出与LDH-A的化学计量结合。选择的分子抑制细胞中乳酸的产生，表明癌细胞系中靶标特异性抑制。
