癌细胞的代谢发生改变以支持快速增殖。肿瘤细胞特异性丙酮酸激酶同工酶 (PKM2) 的药理学激活剂可能是改变癌细胞异常代谢的经典 Warburg 效应特征的一种方法,从而产生一种新的抗增殖策略。在这篇手稿中,我们详细介绍了一系列取代的 N,N'-二芳基磺酰胺作为 PKM2 激活剂的发现。介绍了多种类似物的合成和结构活性关系的评估以及机制和选择性的评估。发现几种试剂具有良好的效力和适当的溶解度,可用作 PKM2 的化学探针,包括 55(AC50 = 43 nM,最大响应 = 84%;溶解度 = 7.3 μg/mL)、56(AC50 = 99 nM,最大响应 = 84%;溶解度 = 5.7 μg/mL)和 58(AC50 = 38 nM,最大响应 = 82%;溶解度 = 51.2 微克/毫升)。这里描述的小分子代表了一流的 PKM2 激活剂
The metabolism of cancer cells is altered to support rapid proliferation. Pharmacological activators of a tumor cell specific pyruvate kinase isozyme (PKM2) may be an approach for altering the classic Warburg effect characteristic of aberrant metabolism in cancer cells yielding a novel anti-proliferation strategy. In this manuscript we detail the discovery of a series of substituted N,N′-diarylsulfonamides as activators of PKM2. The synthesis of numerous analogues and the evaluation of structure activity relationships are presented as well as assessments of mechanism and selectivity. Several agents are found that have good potencies and appropriate solubility for use as chemical probes of PKM2 including 55 (AC50 = 43 nM, maximum response = 84%; solubility = 7.3 μg/mL), 56 (AC50 = 99 nM, maximum response = 84%; solubility = 5.7 μg/mL) and 58 (AC50 = 38 nM, maximum response = 82%; solubility = 51.2 μg/mL). The small molecules described here represent first-in-class activators of PKM2
