    Comparison between metabolite productions in cell culture and in whole plant of Maclura pomifera
    摘要:
    Plant tissue cultures of Maclura pomifera showed a metabolite accumulation pattern which was both quantitatively and qualitatively different from that of the parent plant. Triterpenes and flavonoids were isolated from callus and cell cultures, however, xanthones and stilbenes, which have been reported in the whole plant, were not found. Among the flavonoids, flavones and flavanones were produced preferentially by the suspended cells, but with the prenyl substituents exclusively on ring A, while the isoflavones did not show the 3',4'-dihydroxyl substitution pattern found in the products isolated from fruits. A new prenylated 6'-deoxychalcone was also isolated from the callus and cell cultures.

A series of 35 flavonoid derivatives were synthesized by Winget's condensation, oxidation, and reduction of appropriate acetophenones with appropriate benzaldehydes. The inhibitory activity of these derivatives on rat lens aldose reductase and their
    已知醛糖还原酶,多元醇途径的关键酶和氧化应激在糖尿病并发症中起重要作用。因此,具有有效抑制醛糖还原酶和氧化应激作用的药物将是预防糖尿病并发症的最有前途的药物。这项研究的目的是通过合成查尔酮衍生物,并通过研究抑制大鼠晶状体醛糖还原酶以及抗氧化作用的构效关系,开发出具有上述双重作用的新化合物。通过Winget的缩合,氧化和适当的苯乙酮与适当的苯甲醛的还原反应,合成了35种黄酮类衍生物。这些衍生物对大鼠晶状体醛糖还原酶的抑制活性及其抗氧化作用,评估了使用Cu2 +螯合剂测得的化合物在体外的自由基清除活性。还评估了它们对链脲佐菌素诱发的糖尿病大鼠红细胞,晶状体和坐骨神经中山梨醇积累的影响。在合成的新类黄酮衍生物中,具有A环2',4'-二羟基基团的衍生物,例如2,4,2',4'-四羟基查耳酮(22),2,2',4'-三羟基查耳酮(11 ),发现2',4'-二羟基-2,4-二甲基查耳酮(21)和3,4

    Fifteen chalcones and three thiazolidinedione (TZD) chalcones were prepared to evaluate their peroxisome proliferator-activated receptor-γ (PPAR-γ) ligand-binding activities. Among the three TZDs, one compound possessed PPAR-γ transactivation potential, while the others showed antagonistic activity against PPAR-γ transactivation. Among the chalcones, compound 5 was the most potent, and structure–activity relationship studies indicated that a methoxyl group in position C-4 and hydroxyl group in position C-4′ or 5′ in chalcone plays a key role in determining the potency of PPAR-γ activation.

The present study revealed two very active tyrosinase inhibitors, 2,4,3',4'-hydroxychalcone and 2,4,2',4'-hydroxychalcone (with IC50 of 0.2 and 0.02 microM, respectively). Structure-related activity studies added some understanding of the role and
    抑制酪氨酸酶的化合物可以有效用作脱色剂。我们已经引入了一组单,二,三和四取代的羟基查耳酮作为有效的酪氨酸酶抑制剂,表明决定酪氨酸酶抑制效率的最重要因素是羟基的位置而不是羟基的数目。本研究的目的是研究四羟基查耳酮的不同官能团对其抑制效能的影响,以优化美白剂的设计。评价了四个四氢查耳酮,合成了市售的Butein和其他三个,并测试了它们对酪氨酸酶的抑制作用。结果表明,B环上的2,4-取代间苯二酚亚基对抑制效能的影响最大。将间苯二酚取代基更改为3,5-位置或将其放置在A环上会大大降低化合物的抑制作用。环A上的邻苯二酚亚基充当金属螯合剂(在铜离子存在下)和竞争性抑制剂(在酪氨酸酶存在下),而环B上的邻苯二酚氧化为邻醌(在两种铜存在下)离子和酪氨酸酶)。其中的三种化合物还显示出抗氧化活性,这可能有助于防止色素沉着。对抑制活性和所测试的查耳酮的物理性质(例如解离能和分子平面度)之间的相关性进行检查后,发
