    摘要:
    恶性疟原虫对当前基于青蒿素的联合疗法的广泛耐药性需要发现新药。药理学杂交已成为耐药性的替代方法,可降低药物-药物不良相互作用的风险。在这项研究中,我们通过乙基接头将吡喃并 [2,3-c] 吡唑的支架与 4-氨基喹啉共价连接,合成了一系列新的杂化物。所有合成的杂合分子分别通过对氯喹抗性 (K1) 和敏感 (3D7)恶性疟原虫菌株的体外筛选进行评估。体外评估数据表明,杂交4b对 3D7 菌株(EC 50= 0.0130 ± 0.0002 μM) 和 K1 菌株 (EC 50 = 0.02 ± 0.01 μM),对 Vero 哺乳动物细胞具有低细胞毒性作用。3D7 菌株(SI > 1000)和 K1 菌株(SI > 800)的高选择性指数值以及化合物4b的低抗性指数值表明该化合物的药理作用是由于对 3D7 和 K1 的选择性抑制菌株。分子对接分析还表明,4b记录了对恶性疟原虫乳酸脱氢酶的最高结合

    目的和目的在本研究中,通过简单方便的共沉淀方法,在姜提取物作为还原剂和加帽剂的条件下,开发了纳米颗粒的生物合成方法。材料与方法通过X射线衍射(XRD),扫描电子显微镜(SEM),X射线的光谱能量色散分析(EDS),傅立叶变换红外(FT-IR)和振动样品磁力计对合成后的纳米颗粒进行表征(VSM)技术。根据振动样品磁力计,纳米颗粒在室温下表现出顺磁行为。此外,研究了姜提取物浓度对Co纳米颗粒的UV-Vis吸收的影响。根据UVVis吸收光谱,生姜提取物浓度增加会导致粒径减小。此外,通过芳族醛,丙二腈乙炔羧酸乙酯的一锅四组分反应,在制备喃并[2,3-c]吡唑中研究了合成纳米颗粒的催化性能。结果与结论制得的喃并[2,3-c]吡唑生物在较短的反应时间内以高收率获得,并且纳米催化剂易于使用外部磁体分离,并可以重复使用多次而活性没有明显损失。

    作者:Sanjay Paul、Koyel Pradhan、Sirshendu Ghosh、S.K. De、Asish R. Das

    日期:2014.9
    A new uncapped SnO2 quantum dots (QDs) catalyzed strategy for the synthesis of substituted pyrano [2,3-c]pyrazole and spiro-2-oxindole derivatives has been developed via a multicomponent one pot approach in aqueous medium. The reactions can be performed at low catalyst loadings with excellent functional group tolerance. This communication also reports a comparative study of the efficiency related to the catalytic activity of uncapped SnO2 QDs, oleic acid capped SnO2 QDs, and SnO2 nanoflower. Uncapped SnO2 QDs, capped SnO2 QDs, and SnO2 nanoflower were prepared by simple solvothermal method and characterized by XRD, FESEM, and TEM images. The easy recovery of the catalyst and high yield of the products make the protocol attractive, sustainable, and economic. The catalyst was reused for six cycles with almost unaltered catalytic activity. (C) 2014 Elsevier Ltd. All rights reserved.
