制备方法与用途

简介

柚皮素是柚皮甙的甙元,属于二氢黄酮类化合物。常温下为白色针状结晶(溶于甲醇),能溶于乙醇、乙醚和苯,几乎不溶于水。盐酸镁粉反应呈樱红色,四氢硼钠反应呈红紫色,Molish反应阴性。自然界中主要来源于蔷薇科植物樱花的花蕾及漆树科植物梗树的果实核壳。

黄酮类化合物的母核结构相似,多数成分脂溶性和水溶性不理想,生物利用度低。通过对其结构进行修饰,引入脂溶性或水溶性强的基团,可以提高其脂溶性或水溶性,从而提升生物利用度。结构修饰主要包括羟基的烷基化、酰化、磺化、苷化及形成金属配合物等。

应用

柚皮素具有抗菌、抗炎、抗氧化、止咳祛痰、降血脂、抗癌、解痉、清除自由基、预防和治疗肝病、抑制血小板凝结及抗粥样动脉硬化等多种作用,广泛应用于医药和食品领域。其具体效果如下:

  1. 抗菌:对金黄色葡萄球菌、大肠杆菌、痢疾杆菌和伤寒杆菌等均有较强的抗菌作用。对真菌也有作用,可降低稻瘟菌感染率40-90%,且对人体和家畜无毒。

  2. 抗炎:每天注射20 mg/kg于大鼠腹腔内,能明显抑制羊毛球引起的炎症反应。

  3. 抗癌:对大鼠白血病L1210和肉瘤具有活性。

  4. 解痉及利胆:为黄酮类化合物中作用较强的品种之一。柚皮素能够显著增加实验动物的胆汁分泌量。

生物活性

Naringenin (NSC 34875, S-Dihydrogenistein, NSC 11855, Salipurol) 是一种来源于食用植物的主要黄酮类化合物,对人体健康有益,具有生物活性。它是一种抗氧化剂、自由基清除剂,并能启动碳水化合物代谢和调节免疫系统。

靶点
  • CYP1A2
体外研究

Naringenin 是一种黄酮类化合物,对人体健康有诸多益处。作为一种抗氧化剂、自由基清除剂、抗炎药、糖代谢促进剂及免疫系统的调节剂,Naringenin 在葡萄柚中广泛存在。在体外实验中,这种物质能够减少对DNA的氧化性损伤,并证明了其对人类细胞色素P450同种型CYP1A2具有抑制作用,从而改变某些药物的人类药代动力学。

体内研究

在血糖正常的和非胰岛素依赖型糖尿病大鼠模型中,灌胃给予Naringenin (50 毫克/千克) 后,显著降低了血浆葡萄糖浓度。Naringenin 在小鼠中的LD50大于5克/千克,在大鼠中的LD50同样大于5克/千克。

化学性质
  • 溶于:乙醇、乙醚和苯
  • 几乎不溶于:水
用途

Naringenin 是一种具有抗菌、抗炎、抗癌及解痉利胆作用的天然黄酮类化合物。它还是一种抗氧化剂,自由基清除剂,抗炎化合物,并能促进碳水化合物代谢和调节免疫系统。研究表明,在体外实验中,Naringenin 可减少DNA氧化性损伤,并抑制病毒通过PPAR介导的机制进行长期装配。

    the flavanone core towards better multidrug resistance (MDR) reversal agents, alkylation reactions and chemical modification of the carbonyl moiety was performed (15–39).

  • Accurate Prediction of Glucuronidation of Structurally Diverse Phenolics by Human UGT1A9 Using Combined Experimental and In Silico Approaches
    作者:Baojian Wu、Xiaoqiang Wang、Shuxing Zhang、Ming Hu
    DOI:10.1007/s11095-012-0666-z
    日期:2012.6
    Catalytic selectivity of human UGT1A9, an important membrane-bound enzyme catalyzing glucuronidation of xenobiotics, was determined experimentally using 145 phenolics and analyzed by 3D-QSAR methods. Catalytic efficiency of UGT1A9 was determined by kinetic profiling. Quantitative structure activity relationships were analyzed using CoMFA and CoMSIA techniques. Molecular alignment of substrate structures was made by superimposing the glucuronidation site and its adjacent aromatic ring to achieve maximal steric overlap. For a substrate with multiple active glucuronidation sites, each site was considered a separate substrate. 3D-QSAR analyses produced statistically reliable models with good predictive power (CoMFA: q2 = 0.548, r2 = 0.949, r pred 2  = 0.775; CoMSIA: q2 = 0.579, r2 = 0.876, r pred 2  = 0.700). Contour coefficient maps were applied to elucidate structural features among substrates that are responsible for selectivity differences. Contour coefficient maps were overlaid in the catalytic pocket of a homology model of UGT1A9, enabling identification of the UGT1A9 catalytic pocket with a high degree of confidence. CoMFA/CoMSIA models can predict substrate selectivity and in vitro clearance of UGT1A9. Our findings also provide a possible molecular basis for understanding UGT1A9 functions and substrate selectivity.
    通过实验使用145种酚类化合物,并通过3D-QSAR方法分析,确定了人UGT1A9的催化选择性。UGT1A9是一种重要的膜结合酶,催化外源性物质的葡糖醛酸化反应。通过动力学分析确定了UGT1A9的催化效率。使用CoMFA和CoMSIA技术分析了定量结构活性关系。通过将葡糖醛酸化位点及其相邻的芳香环重叠,实现了底物结构的最大立体重叠。对于具有多个活性葡糖醛酸化位点的底物,每个位点被视为单独的底物。3D-QSAR分析产生了统计上可靠的模型,具有良好的预测能力(CoMFA:q2=0.548,r2=0.949,r pred 2=0.775;CoMSIA:q2=0.579,r2=0.876,r pred 2=0.700)。通过轮廓系数图阐明了底物中负责选择性差异的结构特征。将轮廓系数图叠加在UGT1A9的同源模型的催化口袋中,能够高度自信地识别UGT1A9的催化口袋。CoMFA/CoMSIA模型可以预测底物的选择性和UGT1A9的体外清除率。我们的发现还提供了理解UGT1A9功能和底物选择性的可能分子基础。

    A triazole bridged flavonoid dimer compound library was efficiently constructed via the cycloaddition reaction of a series of flavonoid-containing azides (Az 1-15) and alkynes (Ac 1-17). These triazole bridged flavonoid dimers and their precursor alkyne- and azide-continaing flavonoids were screened for their ability to modulate multidrug resistance (MDR) in P-gp-overexpressed cell line (LCC6MDR), MRPl-overexpressed cell line (2008/MRPl) and BCRP-overexpressed cell line (HEK293/R2 and MCF7-MX100). Generally, they displayed very promising MDR reversal activity against P-gp-, MRPl- and BCRP-mediated drug resistance. Moreover, they showed different levels of selectivity for various transporters. Overall, they can be divided into mono-selective, dual-selective and multi-selective modulators for the P-gp, MRPl and BCRP transporters. The EC50 values for reversing paclitaxel resistance (141 - 340 nM) of LCC6MDR cells, DOX (78 - 590 nM) and vincristine (82 - 550 nM) resistance of 2008/MRPl cells and topotecan resistance (0.9 - 135 nM) of HEK293/R2 and MCF7-MX100 cells were at nanomolar range. Importantly, a number of compounds displayed EC50 at or below 10 nM in BCRP-overexpressed cell lines, indicating that these bivalent triazoles more selectively inhibit BCRP transporter than the P-gp and MRPl transporters. Most of the dimers are notably safe MDR chemosensitizers as indicated by their high therapeutic index values.
