  Synthesis and Antitumor Activity of 1,5-Disubstituted 1,2,4-Triazoles as Cis-Restricted Combretastatin Analogues

  摘要：

  A series of 1-aryl-5-(3',4',5'-trimethoxyphenyl) derivatives and their related 1-(3',4',5'-trimethoxyphenyl)5-aryl-1,2,4-triazoles, designed as cis-restricted combretastatin analogues, were synthesized and evaluated for antiproliferative activity, inhibitory effects on tubulin polymerization, cell cycle effects, and apoptosis induction. Their activity was greater than, or comparable with, that of the reference compound CA-4. Flow cytometry studies showed that HeLa and Jurkat cells treated with the most active compounds 4l and 4o were arrested in the G2/M phase of the cell cycle in a concentration dependent manner. This effect was accompanied by apoptosis of the cells, mitochondrial depolarization, generation of reactive oxygen species, activation of caspase-3, and PA RP cleavage. Compound 41 was also shown to have potential antivascular activity, since it induced endothelial cell shape change in vitro and disrupted the sprouting of endothelial cells in the chick aortic ring assay.

  Efficient Pd supported on ZnO nanoparticles for the ligand-free O-arylation and N-arylation of phenols and various N–H heterocycles with aryl chlorides, bromides, and iodides were readily synthesized and characterized. The amount of palladium on ZnO is 9.84 wt% (0.005 g of the catalyst contains 462 × 10−8 mol% of Pd) which was determined by ICP analysis. This nano sized Pd/ZnO with an average particle

  有效的Pd负载在ZnO纳米颗粒对游离配体- ø -arylation和Ñ酚和与芳基的氯化物，溴化物和碘化物各种N-H杂环的-arylation被容易地合成和表征。ZnO上的钯的量为9.84重量％（0.005g的催化剂包含462×10 -8 mol％的Pd），其通过ICP分析确定。这种纳米级的Pd / ZnO平均粒径为20–25 nm，比表面积为40.61 m 2 g -1，被用作在有机合成中形成C–O和C–N键的新型可重复使用的非均相催化剂。该方案可在没有任何N 2的情况下以令人满意的产率获得芳基化产物或Ar流。催化剂可以被回收和再循环几次而没有明显的活性损失。

  A novel electrochemical route has been developed for the synthesis of 1,5-disubstituted and 1-aryl 1,2,4-triazoles from aryl hydrazines, paraformaldehyde, NH4OAc, and alcohols. In this multicomponent reaction system, alcohols act as solvents as well as reactants and NH4OAc is used as the nitrogen source. With the assistance of reactive iodide radical or I2 and NH3 electrogenerated in situ, this process

  已开发出一种新的电化学路线，用于从芳基肼，低聚甲醛，NH 4 OAc和醇类合成1,5-二取代和1-芳基1,2,4-三唑。在该多组分反应系统中，醇既充当溶剂又充当反应物，而NH 4 OAc被用作氮源。在反应性碘自由基或I 2和NH 3原位电生成的辅助下，此过程可有效避免使用强氧化剂和过渡金属催化剂，并在室温下平稳进行，得到各种各样的1,2， 4-三唑衍生物具有良好的高收率。初步研究表明，反应机理涉及一个自由基过程。
