    新型合成的黄酮衍生物可为增强抗增殖活性所需的结构特征提供重要见解†
    摘要:
    随着许多癌症显示出对当前化学疗法的抗性,寻找新型抗癌药引起了极大的关注。天然类黄酮已被确认为此类计划的有用线索。然而,由于通常缺乏对最佳活性的结构要求的深入了解,因此在实现类黄酮作为抗增殖剂的全部潜力之前,需要进行进一步的研究。本文构建了一个包含76个甲氧基和羟基黄酮及其4-硫代类似物的宽泛文库,并建立了它们与乳腺癌细胞系MCF-7(ER + ve),MCF-7 /的抗增殖活性的结构-活性关系。探测了DX(ER + ve,抗蒽环类)和MDA-MB-231(ER -ve)。在该库中,有42种化合物是新颖的,所有化合物的收率都很高,纯度95%。最有前途的先导化合物,特别是新型羟基4-硫代黄酮美国国家癌症研究所(NCI)进一步评估了15f和16f对多种癌细胞系的抗增殖活性,并显示出显着的生长抑制特征(例如化合物15f:MCF-7(GI 50 = 0.18μM),T-47D(GI 50 = 0.03μM)和MDA-MB-468(GI

    Synthesis and Pharmacological Evaluation of 2'-Hydroxychalcones and Flavones as Inhibitors of Inflammatory Mediators Generation
    摘要:
    2'-Hydroxy-3,4-dimethoxy-3',4'-dimethylchalcone (3a), 2'-hydroxy-3',4',3,4-tetramethoxychalcone (3b), and their corresponding flavones, 3',4'-dimethoxy-7,8-dimethylflavone (4a) and 3',4',7,8-tetramethoxyflavone (4b), were prepared from 3,4-dimethoxycinnamic acid and the respective phenol. The four compounds inhibited enzymic lipid peroxidation and showed weak peroxyl scavenging activity. They also reduced LTB(4) release from human neutrophils stimulated by A23187. The chalcone 3b was the only compound able to inhibit in a concentration-dependent way, synovial human recombinant phospholipase A(2) activity, human platelet TXB(2) generation, and human neutrophil degranulation. This chalcone exerted topical antiinflammatory effects in mice.

    with 5⁻36% total yields using the Aldol condensation reaction as a key reaction. Each chalcone, flavanone, flavonol, and aurone with the 3,4-dihydroxy groups in the B-ring showed high antioxidant activity. Additionally, each of the chalcones, flavanones, flavonols, and aurones with the 2,4-dihydroxy groups in the B-ring showed an excellent whitening ability.

    Control of flavor characteristics of and fresh taste in fruit juice, particularly citrus fruit juice, and especially orange juice, is described. This is achieved by controlling the relative concentrations of (1) limonin, isolimonin and nomilin, (2) polymethoxylated flavones, and (3) limonoid β-D-glucopyranosides to below the threshold taste levels, together with controlling the sugar concentration in the juice.
