    槲皮素-3-β-半乳糖苷及其合成衍生物与 SARS-CoV 3CL(pro) 的结合相互作用:结构-活性关系研究揭示了显着的药效团特征。
    摘要:
    严重急性呼吸综合征相关冠状病毒 (SARS-CoV) 的 3C 样蛋白酶 (3CL(pro)) 是发现抗 SARS 药物最有希望的靶标之一,因为它在病毒生命周期中发挥着关键作用。在这项研究中,通过分子对接、基于 SPR/FRET 的生物测定和诱变研究,一种名为槲皮素-3-β-半乳糖苷的天然化合物被鉴定为蛋白酶的抑制剂。分子模型和 Q189A 突变都表明 Gln189 在结合中起着关键作用。此外,实验证据表明,SARS-CoV 3CL(pro)的二级结构和酶活性不受Q189A突变的影响。在分子建模的帮助下,设计并合成了八种新的天然产物衍生物。生物测定结果揭示了新化合物构效关系的显着特征:(1)槲皮素部分7-羟基的去除降低了衍生物的生物活性;(2)糖部分的乙酰氧基化消除了抑制剂作用;(3)槲皮素7-羟基上引入大的糖取代基是可以耐受的;(4)用其他糖替代半乳糖部分不影响抑制剂效力。这项研究不仅揭示了一类新的化合物作为对抗

The aim of this study was to investigate the structure–activity relationships of quercetin derivatives, with a focus on the influence of functional groups and sugar composition on their antioxidant capacity. A series of quercetin derivatives were therefore prepared and assessed for their DPPH radical scavenging properties. Isoquercetin O-gallates were more potent radical scavengers

  • Design, synthesis, and biological evaluation of a novel series of quercetin diacylglucosides as potent anti-MRSA and anti-VRE agents
    作者:Abugafar M.L. Hossion、Nao Otsuka、Rafiya K. Kandahary、Tomofusa Tsuchiya、Wakano Ogawa、Akimasa Iwado、Yoshito Zamami、Kenji Sasaki
    DOI:10.1016/j.bmcl.2010.02.060
    日期:2010.9
    A series of novel quercetin diacylglucosides were designed and first synthesized by Steglich esterification on the basis of MRSA strains inhibiting natural compound A. The in vitro inhibition of different multidrug resistant bacterial strains and Escherichia coli DNA gyrase B was investigated. In the series, compound 10h was up to 128-fold more potent against vancomycin-resistant enterococci and more effective than A, which represents a promising new candidate as a potent anti-MRSA and anti-VRE agent.

  • Synthesized quercetin derivatives stimulate melanogenesis in B16 melanoma cells by influencing the expression of melanin biosynthesis proteins MITF and p38 MAPK
    作者:Kosei Yamauchi、Tohru Mitsunaga、Mizuho Inagaki、Tohru Suzuki
    DOI:10.1016/j.bmc.2014.04.053
    日期:2014.7
    In order to understand the effect of structure-activity relationships on melanogenesis using B16 melanoma cells, 19 quercetin derivatives were synthesized. Among the synthesized compounds, 3-O-methylquercetin (11) and 3',4',7-O-trimethylquercetin (14) increased melanin content more potently than the positive control theophylline, while exhibiting low cytotoxicity. Compound 11 exhibited less melanogenesis-stimulating activity than compound 14. However, 11 increased the expression of tyrosinase and tyrosinase-related protein 1 (TRP-1) to a greater extent than 14, thereby suggesting that melanogenesis in melanoma cells does not depend solely on the expression of the enzymes catalyzing melanin biosynthesis. Furthermore, 14 also stimulated the expression of the microphthalmia-associated transcription factor (MITF) and p-p38 mitogen activated protein kinase (MAPK), while they were not increased by 11. These results suggest that 11 may enhance the expression of tyrosinase and TRP-1 by regulating the proteasomal degradation of melanogenic enzymes and/or by activating other transcriptional factors regulating enzyme expression.
