    取代 oxindol-3-ylidenes 作为 AMP 激活蛋白激酶 (AMPK) 抑制剂。
    摘要:
    AMP 激活蛋白激酶 (AMPK) 是一种中央代谢调节因子,可促进缺氧下癌症的生长和存活,并在维持癌症干细胞中发挥作用。探究 AMPK 靶向治疗癌症的潜力的一个主要挑战是缺乏有效且选择性的小分子抑制剂。化合物 C 已广泛用作 AMPK 抑制剂,但它缺乏效力且选择性较差。多激酶抑制剂舒尼替尼已证明对 AMPK 活性具有有效的纳摩尔抑制作用,并且具有改进的空间。在这里,我们设计并合成了几个系列的羟吲哚,以确定 AMPK 抑制的结构要求并提高选择性。我们鉴定了两种有效的新型基于羟吲哚的 AMPK 抑制剂,它们被设计为与 AMPK ATP 结合位点中的 DFG 基序相互作用,这一关键特征避免了与舒尼替尼的常见受体酪氨酸激酶靶点的相互作用。通过抑制髓系白血病细胞中乙酰辅酶A羧化酶(ACC)(AMPK的已知底物)的磷酸化,证实了这些羟吲哚与AMPK的细胞结合。有趣的是,尽管 AMPK 在 K562 细胞中高度表达和激活,但这些基于羟吲哚的

    The present invention features formulations of indolinones which compounds are ionizable as free acids or free bases. The formulation is suitable for parenteral or oral administration, wherein the formulation comprises an ionizable substituted indolinone, and a pharmaceutically acceptable carrier therefor. The term “ionizable substituted indolinone” includes pyrrole substituted 2-indolinones which, in addition to being otherwise optionally substituted on both the pyrrole and 2-indolinone portions of the compound, are necessarily substituted on the pyrrole moiety with one or more hydrocarbon chains which themselves are substituted with at least one polar group. The formulations and the compounds themselves are useful for the treatment of protein kinase related disorders as discussed herein.
    本发明涉及吲哚酮的配方,这些化合物作为游离酸或游离碱是可离子化的。该配方适用于静脉或口服给药,其中配方包括可离子化的取代吲哚酮和其药用可接受载体。术语“可离子化的取代吲哚酮”包括吡咯取代的2-吲哚酮,除了在化合物的吡咯2-吲哚酮部分上可选择地被取代外,必须在吡咯基上用一个或多个烃链取代,这些烃链本身被至少一个极性基团取代。如本文所述,这些配方和化合物本身对于治疗蛋白激酶相关疾病是有用的。
