  • Structural Requirements of Flavonoids and Related Compounds for Aldose Reductase Inhibitory Activity.
    作者:Hisashi Matsuda、Toshio Morikawa、Iwao Toguchida、Masayuki Yoshikawa
    DOI:10.1248/cpb.50.788
    日期:——
    The methanolic extracts of several natural medicines and medicinal foodstuffs were found to show an inhibitory effect on rat lens aldose reductase. In most cases, flavonoids were isolated as the active constituents by bioassay-guided separation, and among them, quercitrin (IC50=0.15 μM), guaijaverin (0.18 μM), and desmanthin-1 (0.082 μM) exhibited potent inhibitory activity. Desmanthin-1 showed the most potent activity, which was equivalent to that of a commercial synthetic aldose reductase inhibitor, epalrestat (0.072 μM). In order to clarify the structural requirements of flavonoids for aldose reductase inhibitory activity, various flavonoids and related compounds were examined. The results suggested the following structural requirements of flavonoid: 1) the flavones and flavonols having the 7-hydroxyl and/or catechol moiety at the B ring (the 3′,4′-dihydroxyl moiety) exhibit the strong activity; 2) the 5-hydroxyl moiety does not affect the activity; 3) the 3-hydroxyl and 7-O-glucosyl moieties reduce the activity; 4) the 2–3 double bond enhances the activity; 5) the flavones and flavonols having the catechol moiety at the B ring exhibit stronger activity than those having the pyrogallol moiety (the 3′,4′,5′-trihydroxyl moiety).
    发现,几种天然药材和药用食品的甲醇提取物对大鼠晶状体醛糖还原酶显示抑制作用。在大多数情况下,通过生物测定指导的分离方法,分离得到黄酮类化合物作为活性成分,其中,槲皮苷(IC50=0.15 μM)、愈创木脂苷(0.18 μM)和去甲基芸香糖苷-1(0.082 μM)显示出强的抑制活性。去甲基芸香糖苷-1显示了最强的活性,相当于商品化合成醛糖还原酶抑制剂依帕司他(0.072 μM)的活性。为了阐明黄酮类化合物对醛糖还原酶抑制活性的结构要求,检测了各种黄酮类化合物及相关化合物。结果表明,黄酮类化合物的以下结构要求是:1)具有7-羟基和/或邻苯二酚结构的黄酮和黄酮醇(在B环上的3′,4′-二羟基结构)显示出强的活性;2)5-羟基结构并不影响活性;3)3-羟基和7-O-葡糖基结构降低活性;4)2-3双键增强活性;5)具有邻苯二酚结构的黄酮和黄酮醇显示出比具有连苯三酚结构(3′,4′,5′-三羟基结构)的化合物更强的活性。
  • Flavonoids with M1 Muscarinic Acetylcholine Receptor Binding Activity

    Muscarinic acetylcholine receptor-active compounds have potential for the treatment of Alzheimer’s disease. In this study, a series of natural and synthetic flavones and flavonols was assayed in vitro for their ability to inhibit radioligand binding at human cloned M1 muscarinic receptors. Several compounds were found to possess competitive binding affinity (Ki = 40–110 µM), comparable to that of acetylcholine (Ki = 59 µM). Despite the fact that these compounds lack a positively-charged ammonium group under physiological conditions, molecular modelling studies suggested that they bind to the orthosteric site of the receptor, mainly through non-polar interactions.

    inhibitory activities than that of quercetin. Preliminary SARs analysis showed that hydroxyl groups at C-3′ and C-4′ position in the B-ring and hydroxyl group at C-3 position in the C-ring played key roles in the thrombin inhibitory activity. The findings of this study would provide information for the exploitation and utilization of quercetin as thrombin inhibitor for thrombotic disease treatment.
    在血液中,槲皮素主要以代谢形式存在。为了研究这些槲皮素代谢产物在心血管疾病中的活性,基于体内代谢合成了17种甲基槲皮素衍生物通过凝血酶原时间(PT),活化的部分凝血活酶时间(APTT),凝血酶时间(TT)和纤维蛋白原(FIB)的分析来评估它们的凝血酶抑制活性。结果表明6种甲基槲皮素衍生物具有比槲皮素更强的抑制活性。SAR的初步分析表明,B环的C-3'和C-4'位置的羟基和C环的C-3位置的羟基在凝血酶抑制活性中起关键作用。这项研究的结果将为槲皮素作为凝血酶抑制剂治疗血栓性疾病的开发和利用提供信息。

    with those of the reported values. The parent flavonoid and its chemically modified analogs were investigated for their γ-globin gene induction for the first time. The parent compound 1 exhibited less induced γ-globin gene expression than cisplatin and hemin, the positive controls. 3,4′-Di-O-methylquercetin (7), the modified analog, significantly enhanced γ-globin gene expression with 2.6-fold change at
    当受影响的患者和健康携带者众多时,β-地中海贫血是发展中国家的主要健康问题,从而导致β-珠蛋白链的产生完全不存在或严重减少。使用化学试剂通过激活γ-珠蛋白基因以平衡多余的α-珠蛋白链来增加胎儿血红蛋白(HbF)的产生是另一种治疗方法。因此,寻找具有诱导γ-珠蛋白基因表达特性的分子的研究引起了极大的兴趣。在本报告中,我们发现槲皮素(1)是从药用植物Anaxagorea luzonensis心材中分离的主要类黄酮。促进了γ-珠蛋白基因的表达。的化学修饰1至14甲基醚类似物(2 - 15)中的溶液进行的。这些化合物的结构是根据其光谱数据并与报告值进行比较确定的。首次研究了亲本类黄酮及其化学修饰的类似物的γ-珠蛋白基因诱导作用。与阳性对照顺铂和血红素相比,母体化合物1诱导的γ-珠蛋白基因表达减少。修饰的类似物3,4'- Di - O-甲基槲皮素(7)显着增强了γ-珠蛋白基因表达在8μM处有2.6倍
