    羟基作为“桥梁”通过超共轭增强单分子电导
    摘要:
    为了设计兼具共轭系统和结构灵活性的单分子器件,具有 σ-π 键相互作用的超共轭分子被认为是理想的候选者。在单分子水平的电导研究中,由于涉及的超共轭系统很少,因此构建超共轭系统的策略以及该系统内电子传输的机制仍未得到探索。基于跳跃共轭结构,我们提出了一种使用羟基构建超共轭分子的合理方法,羟基作为与共轭片段相互作用的桥梁。单分子电导的测量表明,与不含羟基的衍生物相比,具有“桥接”羟基的超共轭系统的电导增加了两倍。理论研究表明,超共轭体系中的羟基连接了两个共轭片段的LUMO,并打开了电子传输的空间通道,从而增强了电导。

  • Chalcones and Bis-Chalcones Analogs as DPPH and ABTS Radical Scavengers

    Background:

    A number of synthetic scaffolds, along with natural products, have been identified as potent antioxidants. The present study deals with the evaluation of varyingly substituted, medicinally distinct class of compounds “chalcones and bis-chalcones” for their antioxidant potential.

    Methods:

    In vitro radical scavenging activities were performed on a series of synthetic chalcones 1- 13 and bis-chalcones 14-18.

    Results:

    All molecules 1-18 revealed a pronounced 2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2ʹ- azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals scavenging potential in the ranges of IC50s = 0.58 ± 0.14 - 1.72 ± 0.03 and 0.49 ± 0.3 - 1.48 ± 0.06 μM, respectively. Ascorbic acid (IC50s = 0.5 ± 0.1 and 0.46 ± 0.17 μM for DPPH and ABTS, respectively) was used as a standard radical scavenger.

    Conclusion:

    Structure-activity relationship (SAR) revealed an active participation of various groups, including -SMe and -OMe in scavenging activity.

    背景:许多合成支架物以及天然产物被确定为有效的抗氧化剂。本研究涉及对不同取代、具有药用特性的化合物类别“查尔酮和双查尔酮”进行抗氧化潜力评估。 方法:对一系列合成查尔酮1-13和双查尔酮14-18进行体外自由基清除活性测试。 结果:所有分子1-18在IC50范围内显示出明显的2,2-二苯基-1-苯基-亚硝基DPPH)和2,2'-联苯二(3-乙基苯并噻唑啉-6-磺酸)(ABTS)自由基清除潜力,分别为0.58 ± 0.14 - 1.72 ± 0.03和0.49 ± 0.3 - 1.48 ± 0.06 μM。抗坏血酸DPPHABTS的IC50分别为0.5 ± 0.1和0.46 ± 0.17 μM)被用作标准自由基清除剂。 结论:结构活性关系(SAR)显示了各种基团,包括-SMe和-OMe在清除活性中的积极参与。

  • Chalcones and bis-chalcones: As potential α-amylase inhibitors; synthesis, in vitro screening, and molecular modelling studies

    Despite of a diverse range of biological activities associated with chalcones and bis-chalcones, they are still neglected by the medicinal chemist for their possible alpha-amylase inhibitory activity. So, the current study is based on the evaluation of this class for the identification of new leads as alpha-amylase inhibitors. For that purpose, a library of substituted chalcones 1-13 and bis-chalcones 14-18 were synthesized and characterized by spectroscopic techniques EI-MS and H-1 NMR. CHN analysis was carried out and found in agreement with the calculated values. All compounds were evaluated for in vitro alpha-amylase inhibitory activity and demonstrated good activities in the range of IC50 = 1.25 +/- 1.05-2.40 +/- 0.09 mu M as compared to the standard acarbose (IC50 = 1.04 +/- 0.3 mu M). Limited structure-activity relationship (SAR) was established by considering the effect of different groups attached to aryl rings on varying inhibitory activity. SMe group in chalcones and OMe group in bis-chalcones were found more influential on the activity than other groups. However, in order to predict the involvement of different groups in the binding interactions with the active site of alpha-amylase enzyme, in silico studies were also conducted.
