    名称:
    Design and synthesis of 2-phenylnaphthalenoids and 2-phenylbenzofuranoids as DNA topoisomerase inhibitors and antitumor agents
    摘要:
    Eight 2-phenylnaphthalenoids (2PNs) (3a h) and twenty four 2-phenylbenzofuranoids (2PBF5) (4a-4j, 5a-5j, 6a, 6f-6h) were successfully designed, synthesized and their antiproliferative and in vitro DNA topoisomerase inhibitory activities were evaluated. Nine compounds (four 2PNs and five 2PBFs) showed either Topol or TopoII alpha inhibitory activities. Six compounds (four 2PNs and two 2PBFs) exhibited potent cytotoxicity with IC50 values for 72 h exposure ranging from 0.3 to above 20 mu M against MDA-MB-231, MDA-MB-435, HepG2 and PC3 cell lines. The two 2PBFs displayed comparable and even better antiproliferative as well as TopoII alpha inhibitory activities than 2PNs. Interestingly, the active 2PBFs displayed different mechanisms of TopoII alpha inhibition from that of 2PNs, suggesting that the chromophore scaffold replacement may result in a change of the binding site of inhibitors to TopoII alpha. Furthermore, the mechanisms of antiproliferation on MDA-MB-231 cells indicate that compounds 5a and 5f are promising for further development of anticancer agents. The results of this study reveal that the evolutionary strategy of medicinal chemistry through scaffold hopping is a promising strategy for structure optimization of TopoII alpha inhibitors.

    寻找新的黄嘌呤氧化酶抑制剂:3-苯基香豆素与2-苯基苯并呋喃。
    摘要:
    体内尿酸的过度产生会导致高尿酸血症,这也与痛风密切相关。黄嘌呤氧化酶(XO)抑制剂可降低尿酸的产生。还已经提出抑制XO作为改善心血管健康的机制。因此,寻找新的有效XO抑制剂是药物发现中一个有趣的话题。3-苯基香豆素和2-苯基苯并呋喃是药物化学中的特有支架。它们的结构相似性使其成为有趣的分子以进行比较研究。在两个支架中都引入了甲氧基和硝基取代基。当前的研究对这些分子针对该重要靶标的合成和生物学活性提供了一些见识。对于该系列中最好的化合物,3-(4-甲氧基苯基)-6-硝基香豆素(4),确定IC 50值,抑制类型,对B16F10细胞的细胞毒性和ADME理论性质。还进行了对接研究,以更好地了解该分子与XO结合口袋的相互作用。这项工作是初步筛选,以进一步设计和合成新的非嘌呤能衍生物,作为潜在的参与炎症抑制的化合物,特别是与痛风有关。

    Recently, we have developed a method for catalytic regioselective synthesis of 2-substituted and 3-substituted benzofurans starting from phenols. The choice of reacting partner, olefin versus α,β-unsaturated acid, is critical to dictate the isomeric product formation. Instances are known where these olefinic partners did not complement each other and yield a similar outcome. In the current work, we
    最近,我们已经开发了一种从苯酚开始催化区域选择性合成2取代和3取代的苯并呋喃的方法。选择反应伙伴,烯烃还是α,β-不饱和酸,对决定异构产物的形成是至关重要的。已知这些烯烃伙伴彼此不互补且产生相似结果的情况。在当前的工作中,我们解决了这一悖论,重点是(a)正交选择性的起源和(b)预期互补行为的关键要求。实验和计算研究提供了重要的力学见解。发现在迁移插入过程中的静电相容性和在催化步骤中羧酸部分的定位在确定区域选择性方面发挥了至关重要的作用。

The study demonstrated α-Syn-PdNPs to be a superior heterogeneous catalyst for the synthesis of pharmaceutically valuable benzofuran, naphthofuran, coumarin and N-arylindole via C–H activation. Further, the electrooxidation of ethanol using α-Syn-PdNPs displayed an electrochemically active surface area of 160.6
    淀粉样蛋白是高度有序的纳米原纤维,其抗张强度与钢相似,因此可以抵抗极端的pH和温度。基于此原理,我们证明了以α-突触核蛋白(α-Syn)原纤维为模板,可以轻松合成钯,铜,铂,金和银纳米复合材料。我们表明,α-Syn-原纤维-钯纳米颗粒(α-Syn-PdNPs)复合材料可以用作C–H键活化和乙醇电氧化的非均相催化剂。研究表明,α-Syn-PdNPs是一种优异的非均相催化剂,可通过以下方法合成药学上有价值的苯并呋喃,萘并呋喃,香豆素和N-芳基吲哚。C–H激活。此外,使用α-Syn-PdNPs对乙醇进行的电氧化表现出160.6 m 2 g -1的电化学活性表面积,该表面积比先前报道的负载Pd纳米复合材料的值高得多。

    Monoamine oxidase (MAO) is an important drug target for the treatment of neurological disorders. Several 3‐arylcoumarin derivatives were previously described as interesting selective MAO‐B inhibitors. Preserving the trans‐stilbene structure, a series of 2‐arylbenzofuran and corresponding 3‐arylcoumarin derivatives were synthesized and evaluated as inhibitors of both MAO isoforms, MAO‐A and MAO‐B. In general
    单胺氧化酶(MAO)是治疗神经系统疾病的重要药物靶标。以前有几种3-芳基香豆素衍生物被描述为有趣的选择性MAO-B抑制剂。保留了反式二苯乙烯结构,合成了一系列的2-芳基苯并呋喃衍生物和相应的3-芳基香豆素衍生物,并将其评估为MAO-A和MAO-B的抑制剂。通常,发现两种类型的衍生物都是选择性的MAO-B抑制剂,IC 50值在纳摩尔至微摩尔范围内。5-硝基-2-(4-甲氧基苯基)苯并呋喃(8)是苯并呋喃系列中活性最高的化合物,具有MAO-B选择性和可逆抑制作用(IC 50 = 140 n M)。具有与化合物8相同的取代模式的3-(4'-甲氧基苯基)-6-硝基香豆素(15)被发现是香豆素系列中活性最高的MAO-B抑制剂(IC 50 = 3 n M) 。但是,3-苯基香豆素14的活性在相同范围内(IC 50 = 6 n M),可逆,并且选择性也比化合物15高出几倍。将最具活性的化合物对接到MAO
