    Semisynthesis of Natural Flavones Inhibiting Tubulin Polymerization, from Hesperidin
    摘要:
    Semisynthesis of 5,3'-dihydroxy-3,6,7,8,4'-pentamethoxyflavone (1), a natural flavone that binds with high affinity to tubulin, was performed from hesperidin, the very abundant Citrus flavanone, by a five-step sequence. The last step of the synthesis also gave rise to 5,3'-dihydroxy-3,6,7,4'-tetramethoxyflavone (= casticin or vitexicarpin) (10), 5,3'-dihydroxy-3,7,8,4'-tetramethoxyflavone (= gossypetin 3,7,8,4'-tetramethyl ether) (11), and, unexpectedly, 5,7,3'-trihydroxy-3,6,8,4'tetramethoxyflavone (12) and 5,3'-dihydroxy-8-dimethylamino-3,6,7,4'-tetramethoxyflavone (= 8-dimethylaminocasticin) (13). Cytotoxicity and antitubulin activity of these five flavones, as well as 5,3'-dihydroxy-3,7,4'-trimethoxyflavone (= ayanin) (14) and intermediate 6,8-dibromo-ayanin (8), were evaluated. Comparison of the responses confirmed and clarified the influence of the A-ring substitution pattern on the biological activity.

    (OH) groups of quercetin (3,5,7,3',4'-pentahydroxyflavone), the OH group at 5 position is the most resistant to methylation due to its strong intramolecular hydrogen bonding with the carbonyl group at 4 position. Thus, it is generally difficult to synthesize the pentamethyl ether efficiently by conventional methylation. Here, we describe a simple and effective per-O-methylation of quercetin with dimethyl

  • Structural Requirements of Flavonoids and Related Compounds for Aldose Reductase Inhibitory Activity.
    作者:Hisashi Matsuda、Toshio Morikawa、Iwao Toguchida、Masayuki Yoshikawa

    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。

    histamine-induced precontraction, the potency order was quercetin 3,3',4,'5,7-pentamethyl ether (QPME), quercetin 3-methyl ether > quercetin, quercetin 3,4',7-trimethyl ether (ayanin) > quercetin 4'-methyl ether (tamarixetin), quercetin 3,3',4',7,-tetramethyl ether (QTME). Therefore, the methylation at 3, at 5, and at both 3 and 7 positions of the A or/and C ring of quercetin nucleus may increase their tracheal relaxant
    在本研究中,我们试图比较槲皮素甲醚并寻找构效关系,这可能有助于合成更多治疗哮喘的活性化合物。四个目前和两个以前研究过的槲皮素甲基醚浓度依赖地放松组胺 (30 microM)、carbachol (0.2 microM) 和氯化钾 (30 mM) 诱导预收缩。根据它们对组胺诱导的预收缩的 IC25 值,效力顺序为槲皮素 3,3',4,'5,7-五甲基醚 (QPME)、槲皮素 3-甲基醚 > 槲皮素、槲皮素 3,4',7-三甲醚 (ayanin) > 槲皮素 4'-甲基醚 (tamarixetin),槲皮素 3,3',4',7,-四甲醚 (QTME)。因此,在 3、5、在槲皮素核的A或/和C环的第3和第7位可增加其气管松弛活性。然而,槲皮素核B环3'和4'位置的甲基化可能会降低其气管松弛活性。

    and in vitro antiplasmodial activity on two strains of P. falciparum. Stability of heme adducts was discussed using the dissociation voltage at 50% (DV50). No correlation was observed between the methoxylation pattern and the antiparasitic activity, either for the 3D7 chloroquine-sensitive or for the W2 chloroquine-resistant P. falciparum strains. However, in each PMF family an increased DV50 was observed
    通过仿生MS测定法评估了33个聚甲氧基黄酮(PMF)库的血红素结合亲和力以及对两株恶性疟原虫的体外抗血浆活性。使用50%的解离电压(DV 50)讨论了血红素加合物的稳定性。对于3D7氯喹敏感或耐W2氯喹的恶性疟原虫菌株,甲氧基化模式与抗寄生虫活性之间均未发现相关性。但是,在每个PMF家庭中,DV增加了50观察到在位置5处被甲氧基化的衍生物。测量了选定衍生物的红细胞内血红蛋白形成,并且血红蛋白浓度与血红素结合亲和力成反比。山emp酚对血红蛋白的形成没有影响,强化了该化合物可能主要通过其他途径发挥体外抗血浆活性的假说。五甲氧基槲皮素同时已显示出显着的生物学活性和与血红素的强相互作用,表明抑制血zo素的形成完全或部分负责其抗寄生虫作用。

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。
