of a fully functionalized small‐molecule library with competitive affinity‐based proteome profiling to map and functionally characterize the targets of screening hits. Using this approach, we identified ANXA2, PDIA3/4, FLAD1, and NOS2 as primary cellular targets of two bioactive molecules that inhibit cancer cell proliferation. We further demonstrated that a panel of probes can label and/or image annexin
靶标识别表型筛选一直是药物发现的有力方法。但是,由于难以识别潜在的细胞靶标而受到阻碍。为了应对这一挑战,我们将功能齐全的小分子文库的表型筛选与基于竞争性亲和力的蛋白质组图谱相结合,以绘制和表征筛选命中目标。使用这种方法,我们确定了ANXA2,PDIA3 / 4,FLAD1和NOS2是抑制癌细胞增殖的两种生物活性分子的主要细胞靶标。我们进一步证明,一组探针可以标记和/或成像来自不同癌细胞系的膜联蛋白A2(一种癌症生物标志物),从而为潜在的癌症诊断和治疗提供了机会。
