    Dual functional small molecule fluorescent probes for image-guided estrogen receptor-specific targeting coupled potent antiproliferative potency for breast cancer therapy
    摘要:
    A strategy by integrating biological imaging into early stages of the drug discovery process can improve our understanding of drug activity during preclinical and clinical study. In this article, we designed and synthesized coumarin-based nonsteroidal type fluorescence ligands for drug-target binding imaging. Among these synthesized compounds, 3e, 3f and 3h showed potent ER binding affinity and 3e (IC50 = 0.012 mu M) exhibited excellent ERo: antagonistic activity, its antiproliferative potency in breast cancer MCF-7 cells is equipotent to the approved drug tamoxifen. The fluorescence of compounds 3e and 3f depended on the solvent properties and showed significant changes when mixed with Elta or ER/3 in vitro. Furthermore, target molecule 3e could cross the cell membrane, localize and image drug-target interaction in real time without cell washing. Thus, the coumarin-based platform represents a promising new ER-targeted delivery vehicle with potential imaging and therapeutic properties. (C) 2017 Elsevier Ltd. All rights reserved.

    worked well. The methodology was extended to 2-coumarins and applied to the synthesis of flemichapparin C and a novel analogue. Deuterium isotope effects, typical of a concerted metalation-deprotonation (CMD) mechanism, were observed in the case of a bromopyrone, but a highly unusual, inverse kinetic isotope effect was evident using a chlorocoumarin, implying that a different mechanism is operating.
    直接芳基化代表了传统交叉偶联的有利替代方法,并已发现可广泛用于简单的芳基和坚固的杂环。在此,直接芳基化方案已被优化并应用于2-吡喃酮,2-吡喃酮是精致且具有特权的生物基序。在3-位的区域选择性卤化允许通过激活吡喃酮C-Br或C-Cl键和苯氧基CH键进行分子内偶联。重要的是,贫电子苯氧基底物也能很好地工作。该方法扩展到了2-香豆素,并用于合成氟苯丙胺林C和一种新的类似物。在溴吡喃酮的情况下,观察到氘同位素效应,这是协同金属化-去质子化(CMD)机制的典型特征,但是使用氯香豆素可明显观察到非常不寻常的逆动力学同位素效应,

    Pd-catalyzed spiroannulation of 4-bromocoumarin with alkynes has been illustrated. The reaction highlights an interesting process for cascade formation of two five-membered rings through spiroannulation followed by cyclization via C–H activation. This method offers an attractive platform for the synthesis of a broad range of indane-fused spiropentadiene chromanones in good yields.

    enhanced fluorogenic properties compared with the commonly used ninhydrin. These types of derivatives can be potentially used for development of the latent prints on the dark surfaces, because their ninhydrin reaction products provide fluorescent prints under the UV light. The prints developed using these compounds are stable, visible and do not vanish from paper for a relatively long time (5 months). Graphical
