  摘要：

  设计，合成和评估了新型吡唑基苯并[d]咪唑衍生物（2a-2f），并针对四种属于α家族的人碳酸酐酶同工型，其中包括两个胞质同工型hCA I和II，以及两个跨膜肿瘤相关同工型hCA IX和XII。从显示出高效力但低选择性的这些衍生物开始，支持肿瘤相关同工型hCA IX和XII，我们研究了去除磺酰胺基团的影响。因此，合成了没有磺酰胺部分的类似物3a-3f，并且生物学测定显示出作为与肿瘤相关的hCA IX和hCA XII的抑制剂的良好的活性以及优异的选择性，并且通过分子对接研究对其进行了分析。

  The conversion of aldehydes into carboxylic acids using oxidizing agents is a common protocol in transformation chemistry. An efficient oxidation strategy of transformation of pyrazole‐4‐aldehydes to the corresponding acids using vanadium catalysts in the presence of 30% H2O2 as an oxidant is described. The catalytic technology was successfully applied to a range of various 4‐formylpyrazoles, and plausible

  日期：——

  A solvent-free green synthesis of N-sulfonylformamidines is reported via the direct condensation of N,N-dimethylformamide dimethyl acetal (DMF-DMA) and sulfonamide derivatives at room temperature. The described method avoids the use of metal catalysts as well as hazardous solvents, which are not permitted for pharmaceutical manufacture, for the reactions or isolation of products. Hence, the current work presents a fast and efficient alternative to earlier reported methods. The mild nature of the procedure is demonstrated by varied functional group tolerance.

  报道了一种无溶剂的绿色合成N-磺酰基甲酰胺的方案，通过在室温下直接冷凝N,N-二甲基甲酰胺二甲基缩醛(DMF-DMA)和磺酰胺衍生物。该方法避免了使用金属催化剂以及对药物生产不允许的危险溶剂，从而用于反应或产品的分离。因此，目前的工作提供了一种比之前报道的方法更快速高效的替代方案。该程序的温和特性通过不同功能团的耐受性得到了验证。

  1,3-Diaryl-4-formylpyrazoles 8 bearing benzenesulfonamide moiety at position-1 were synthesized as important intermediates following Vilsmeier-Haack strategy. Aldehyde moiety of 4-formylpyrazole was then converted into carboxylic acid 9, cyano 10 and carbothioamide 11 using established procedures. Out of these 4-functionalized pyrazoles, pyrazole-4-carboxylic acids 9 and carbothioamides 11 were evaluated for their in vitro antibacterial activity against four pathogenic bacterial strains namely, Staphylococcus aureus, Bacillus subtilis (Gram-positive), Escherichia coli, Pseudomonas aeruginosa (Gram-negative), and in vitro antifungal activity against two pathogenic fungal strains namely, Aspergillus niger and Aspergillus flavus. Three tested compounds, 9e, 11b and 11f exhibited moderate antibacterial activity against Gram-positive bacteria and 9g showed moderate antifungal activity against the tested fungi. However, none of the compounds showed any activity against Gram-negative bacteria. (c) 2011 Elsevier Masson SAS. All rights reserved.

  In this study, 4-(2-substituted hydrazinyl)benzenesulfonamides were synthesized by microwave irradiation and their chemical structures were confirmed by H-1 NMR, (CNMR)-C-13, and HRMS. Ketones used were: Acetophenone (S1), 4-methylacetophenone (S2), 4-chloroacetophenone (S3), 4-fluoroacetophenone (S4), 4-bromoacetophenone (S5), 4-methoxyacetophenone (S6), 4-nitroacetophenone (S7), 2-acetylthiophene (S8), 2-acetylfuran (S9), 1-indanone (S10), 2-indanone (S11). The compounds S9, S10 and S11 were reported for the first time, while S1-S8 was synthesized by different method than literature reported using microwave irradiation method instead of conventional heating in this study. The inhibitory effects of 4-(2-substituted hydrazinyl) benzenesulfonamide derivatives (S1-S11) against hCA I and II were studied. Cytosolic hCA I and II isoenzymes were potently inhibited by new synthesized sulphonamide derivatives with K-is in the range of 1.79 +/- 0.22-2.73 +/- 0.08 nM against hCA I and in the range of 1.72 +/- 0.58-11.64 +/- 5.21nM against hCA II, respectively.
