mitochondria-disruptive agents. The starting materials used for the synthesis of these new aminocarbazoles are oxopentanoate derivatives of tryptophan. The scope and limitation of this method of synthesis are determined by a series of experiments. The prepared carbazole derivatives are screened for their in vitro anticancer activity against a broad panel of human cancer cells and normal cell lines. Among the tested
线粒体靶向在抗癌治疗中起着重要作用。Mn(III) 促进的 5-(1H-indol-3-yl)-3-oxopentanoic 酸的环化允许获得可作为线粒体破坏剂的新型取代咔唑衍生物。用于合成这些新氨基咔唑的起始材料是色氨酸的氧代戊酸酯衍生物。这种合成方法的范围和局限性是由一系列实验确定的。筛选制备的咔唑衍生物对广泛的人类癌细胞和正常细胞系的体外抗癌活性。在测试的化合物中,对人结肠癌细胞 (HCT-116) 和人骨骨肉瘤 (U-2 OS) 的活性最强的化合物在体外进行了复杂的检测细胞分析,包括细胞周期分布、细胞内区室化、抗迁移特性、活性氧的线粒体生成、DNA 损伤和细胞死亡类型的研究。结果表明,合成的化合物显示出强大的氧化活性,可诱导 DNA 双链断裂的大量积累,从而导致线粒体组装的平行变化,从而导致其功能障碍。这些发现为结肠癌和骨肉瘤的治疗提供了新的线索。

The present invention relates to a method of modulating pluripotency and/or self-renewing characteristics of a stem/progenitor cell. The method comprises administering to the respective cell a compound of the general formula (I)
In the general formula A is C or N. R1, R4 and R5 are, independently selected, H or aliphatic, cycloaliphatic, aromatic, arylaliphatic, or arylcycloaliphatic hydrocarbyl groups, that comprise 0 - 3 heteroatoms being N, O, S, or Si. R4 and R5 may optionally be linked so as to define an aliphatic hydrocarbyl bridge. R2 is H or a halogen, such as F or Cl. R3 is H, or an aliphatic or arylaliphatic hydrocarbyl group comprising 1 - 8 main chain carbon atoms and 0 - 3 heteroatoms being N, O, S, Si, or a halogen such as Cl or F. Also provided is a method for modulating gene expression in a cell that expresses the components of a polycomb repressive complex.
本发明涉及一种调节干细胞/祖细胞多能性和/或自我更新特性的方法。该方法包括向各细胞施用通式(I)化合物
在通式中,A 是 C 或 N。R1、R4 和 R5 独立地选自 H 或脂肪族、环脂族、芳香族、芳脂族或芳环脂族烃基,其中包括 0 - 3 个杂质原子 N、O、S 或 Si。R4 和 R5 可选择性地连接,以形成脂族烃桥。R2 是 H 或卤素,如 F 或 Cl。R3 是 H,或脂肪族或芳脂族烃基,包括 1 - 8 个主链碳原子和 0 - 3 个 N、O、S、Si 或卤素(如 Cl 或 F)杂原子。 还提供了一种调节表达多聚抑制复合体成分的细胞中基因表达的方法。
