  摘要：

  提供了一种新型丙酮酸激酶M2（PKM2）特异性激活剂，[11C]DASA-23及其衍生物，以及它们的快速合成方法。这些探针在非侵入性正电子发射断层扫描（PET）检测和影像化亚表皮和原位肿瘤中PKM2表达的方法中特别有用。[11C]DASA-23的细胞摄取与培养肿瘤细胞中PKM2蛋白表达相关，并且在体内将原位肿瘤与周围正常脑组织分开。

  A novel pyruvate kinase M2 (PKM2)-specific activator, [11C]DASA-23 and derivatives thereof, and methods for their rapid synthesis are provided. The probes are particularly useful in methods for the non-invasive positron emission tomography (PET) detection and imaging of PKM2 expression in subcutaneous and orthotopic tumors. [11C]DASA-23 cell uptake correlates with PKM2 protein expression in cultured tumor cells and orthotopic tumors are delineated from the surrounding normal brain tissue in vivo.

  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 (AC(50) = 43 nM, maximum response = 84%; solubility = 7.3 mu g/mL), 56 (AC(50) = 99 nM, maximum response 84%; solubility = 5.7 mu g/mL), and 58 (AC(50) = 38 nM, maximum response = 82%; solubility 51.2 mu g/mL). The small molecules described here represent first-in-class activators of PKM2
