  • Structure-activity Relationships for α-Glucosidase Inhibition of Baicalein, 5,6,7-Trihydroxyflavone: the Effect of A-Ring Substitution
    作者:Hong GAO、Tetsuo NISHIOKA、Jun Kawabata、Takanori KASAI
    DOI:10.1271/bbb.68.369
    日期:2004.1
    In order to estimate the effects of the A-ring hydroxyl group of baicalein (5,6,7-trihydroxyflavone, 1) on rat intestinal α-glucosidase inhibition, flavone, monohydroxyflavones, dihydroxyflavones, and methylated derivatives of 5,6,7-trihydroxyflavone were used for the structure-activity relationship (SAR) study. The importance of the 6-hydroxyl group of baicalein was validated for an exertion of the activity. And also, the tested flavones which lacked a hydroxyl substituent on any of positions 5, 6, or 7, showed no activity. Hence, the 5,6,7-trihydroxyflavone structure was concluded to be crucial for the potent inhibitory activity. In addition, an introduction of electron-withdrawing or electron-donating groups at position 8 of baicalein led to a dramatic decrease for activity, except for 8-fluoro-5,6,7-trihydroxyflavone, which carried a less bulky substituent on position 8. Hence, this result suggested that a sterically bulky substituent on C-8 of baicalein was detrimental for the activity regardless of its electronic nature. Through examining the inhibitory mechanism of baicalein against rat intestinal α-glucosidase, it was suggested to be a mixed type inhibition.
    为了估计黄芩(5,6,7-三羟基黄酮,1)的A环羟基对大鼠肠α-葡萄糖苷酶抑制的影响,采用了黄酮、单羟基黄酮、二羟基黄酮及5,6,7-三羟基黄酮的甲基化衍生物进行结构-活性关系(SAR)研究。验证了黄芩的6-羟基对该活性的发挥的重要性。此外,测试的黄酮若在5、6或7位上缺乏羟基取代基,则显示无活性。因此,得出5,6,7-三羟基黄酮结构对强抑制活性至关重要的结论。此外,在黄芩的8位引入电子吸引或电子给体基团会使活性急剧降低,唯独8-氟-5,6,7-三羟基黄酮因其在8位上带有体积较小的取代基而例外。因此,该结果表明,黄芩C-8上的空间庞大取代基无论其电子性质如何,对活性都是不利的。通过研究黄芩对大鼠肠α-葡萄糖苷酶的抑制机制,建议其为混合型抑制。

    A series of 6,8-disubstituted chrysin derivatives have been synthesized and evaluated for their PGE2 inhibitory activities. 6,8-Disubstituted chrysin derivatives were obtained from naturally occurring chrysin by halogenation, oxidation, thiomethylation and C-C cross coupling reaction. Among the compounds investigated, 6,8-dibromochrysin (2), 6,8-diiodochrysin (4), 6,8-dimethylthiochrysin (9) and 6

    Flavones are a group of plant secondary metabolites with multiple biological properties. In the present study, 5,6,7,8-tetrahydroxyflavone (5,6,7,8-THF) was synthesized and characterized. In vitro antioxidant study, the effect of 5,6,7,8-THF on total antioxidant activity, reducing power, DPPH radical scavenging, ABTS radical scavenging, superoxide radical scavenging, hydroxyl radical scavenging, nitric oxide radical scavenging, and ferrous chelating activities was examined. According to the results, 5,6,7,8-THF showed excellent free radical scavenging effect and reducing power but weak the ferrous chelating activity. In conclusion, 5,6,7,8-THF can be regarded as an excellent source of antioxidants.
