  • Discovery of a Prenylated Flavonol Derivative as a Pin1 Inhibitor to Suppress Hepatocellular Carcinoma by Modulating MicroRNA Biogenesis
    作者:Yuanyuan Zheng、Wenchen Pu、Jiao Li、Xianyan Shen、Qiang Zhou、Xin Fan、Sheng-Yong Yang、Yamei Yu、Qiang Chen、Chun Wang、Xin Wu、Yong Peng

    isomerase Pin1 plays a crucial role in the development of human cancers. Recently, we have disclosed that Pin1 regulates the biogenesis of miRNA, which is aberrantly expressed in HCC and promotes HCC progression, indicating the therapeutic role of Pin1 in HCC therapy. Here, 7‐(benzyloxy)‐3,5‐dihydroxy‐2‐(4methoxyphenyl)‐8‐(3‐methylbut‐2‐en‐1‐yl)‐4H‐chromen‐4‐one (AF‐39) was identified as a novel Pin1
    肽脯酰顺-反异构酶中Pin1在人类癌症的发展至关重要的作用。最近,我们披露了Pin1调节miRNA的生物发生,miRNA在HCC中异常表达并促进HCC进展,表明Pin1在HCC治疗中的治疗作用。在此,7-(苄基)-3,5-二羟基-2-(4-甲氧基苯基)-8-(3-甲基丁-2--1-基)-4H--4--1(AF-39)被鉴定为新型的Pin1抑制剂。生化试验表明,AF-39有效抑制中Pin1活性,其IC 50的1.008μ值米,并且还显示中肽基脯酰异构酶对中Pin1高选择性。此外,AF‐39以剂量和时间依赖性方式显着抑制HCC细胞的细胞增殖。从机制上讲,AF-39调节XPO5的亚细胞分布并增加HCC细胞中miRNA的生物发生。这项工作为HCC治疗提供了有希望的先导化合物,突出了基于miRNA的疗法对人类癌症的治疗潜力。
  • Synthesis of Flavonols via Pyrrolidine Catalysis: Origins of the Selectivity for Flavonol versus Aurone

    method for flavonol from 2′-hydroxyl acetophenone and benzaldehyde promoted by pyrrolidine under an aerobic condition in water is established. This protocol was supported by efficient synthesis of 44 common examples and three natural products. The α, β-unsaturated iminium ion (enimine ion E) was proved to be the key intermediate in the reaction. H218O and 18O2 isotope tracking experiments demonstrated
    建立了一种在中好条件下由吡咯烷促进的2'-羟基苯乙酮苯甲醛合成黄酮醇的新方法。该协议得到44个常见实例和三种天然产物的有效合成的支持。事实证明,α,β-不饱和亚胺离子(亚胺离子E)是反应的关键中间体。H 2 18 O和18 O 2同位素跟踪实验表明,和好氧气氛对于确保转化都必不可少。黄酮醇或的选择性源自溶剂触发的中间体,该中间体由分离的亚胺的紫外可见光谱确定。亚胺EA在中占主导地位,中间体EB在乙腈中盛行。在环化和[2 + 2]化的关键步骤之后,在吡咯烷和的存在下,EA通过EI(两性离子样的亚胺离子)通过EI生成黄酮醇。EB通过路径II进行,这是由EB与吡咯烷和氧气共同光解而引发的自由基过程,从而生成。初步的机械研究报道。

  • 4'-Hydroxy-3-methoxyflavones with potent antipicornavirus activity
    作者:Nadine De Meyer、Achiel Haemers、Lallan Mishra、Hrishi Kesh Pandey、L. A. C. Pieters、Dirk A. Vanden Berghe、Arnold J. Vlietinck

    4'-Hydroxy-3-methoxyflavones are natural compounds with known antiviral activities against picornaviruses such as poliomyelitis and rhinoviruses. In order to establish a structure-activity relationship a series of analogues were synthesized, and their antiviral activities and cytotoxicities were compared with those of flavones from natural origin. The 4'-hydroxyl and 3-methoxyl groups, a substitution in the 5 position and a polysubstituted A ring appeared to be essential requirements for a high activity. The most interesting compound was 4',7-dihydroxy-3-methoxy-5,6-dimethylflavone possessing in vitro TI99 values of > 1000 and > 200 against poliovirus type 1 and rhinovirus type 15, respectively. This compound was also active against other rhinovirus serotypes (2, 9, 14, 29, 39, 41, 59, 63, 70, 85, and 89) tested, having MIC50 values ranging from 0.016 to 0.5-mu-g/mL. Finally in contrast to quercetin it showed to be not mutagenic in concentrations up to 2.5 mg in the Ames test.
