    report the concise and divergent total syntheses of several naturally occurring dihydrochalcones and 5-deoxyflavones from readily available starting materials. The divergent strategy is based around manipulation of a common chalcone scaffold and features application of Algar–Flynn–Oyamada oxidation and benzoquinone C–H activation methodologies. These are the first reported total syntheses of these biologically

    A series of scopoletin derivatives incorporated with the pyridinium moiety was synthesized and evaluated for their acetylcholinesterase (AChE) inhibitory activity by the colorimetric Ellman’s method. A 2-fluorobenzylpyridinium derivative was the most potent among the tested compounds, with an IC50 value of 0.215 ± 0.015 μM, which was greatly improved from that of scopoletin. Docking studies revealed

    hepatocellular carcinoma (HCC). Erianin modulated cancer-related gene expression and induced changes in metabolic intermediates. Moreover, erianin promotes mitochondrial oxidative stress and inhibits glycolysis, leading to insufficient energy required for cell proliferation. Analysis of 14 natural analogs of erianin showed that some compounds exhibited potent inhibitory effects on PC. These results suggest that
    一些器官中的癌细胞增殖通常依赖于丙酮酸通过丙酮酸羧化酶 (PC) 转化为草酰乙酸,以补充三羧酸循环以支持生物质生产。在这项研究中,使用基于光亲和标记-点击化学的探针策略将 PC 鉴定为毛兰素的细胞靶标。Erianin 有效抑制 PC 的酶活性,从而介导 erinin 在人肝细胞癌 (HCC) 中的抗癌作用。Erianin 调节癌症相关基因的表达并诱导代谢中间体的变化。此外,毛兰素促进线粒体氧化应激并抑制糖酵解,导致细胞增殖所需的能量不足。对 14 种毛兰素天然类似物的分析表明,一些化合物对 PC 表现出有效的抑制作用。这些结果表明 PC 是 erinin 的细胞靶点,并揭示了 PC 在 HCC 肿瘤发生中未被识别的功能;毛兰素及其类似物需要进一步开发作为治疗 HCC 的新治疗策略。
