  摘要：

  在这项研究中，一系列含有5-芳氧基吡唑部分的绕丹宁衍生物被鉴定为具有抗炎和抗癌特性的潜在药物。大多数合成的化合物都表现出抗炎和抗癌活性。值得注意的是，与参考药物塞来昔布（52.5%）和氢化可的松（79.4%）相比，化合物7g （94.1%）表现出显着的抗炎活性。不同浓度的化合物7g以剂量依赖性方式有效抑制一氧化氮(NO)的产生。 Western blot结果显示，化合物7g可以阻止LPS诱导的巨噬细胞炎症介质的表达。酶联免疫吸附测定 (ELISA) 测定表明7 g是一种有前途的化合物，能够阻断 COX-2 的下游信号传导。总之，这些发现表明化合物7 g可能是进一步研究的有希望的候选者。

  日期：——

  In this paper, a series of 2-[(5-phenoxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-methylene]hydrazine carboxamides were synthesized and evaluated for their anticonvulsant activities using the maximal electroshock method. Their neurotoxicities were determined applying the rotarod test. Interestingly, all compounds showed anticonvulsant activity with long duration of protection effects in the maximal electroshock test. Among which, compound 5m was found to have promising anticonvulsant activity, which gave an ED50 of 42.4 mg/kg and a protective index value of 3.7, possessing better anticonvulsant activity and higher safety than marketed drugs valproate, but weaker than phenobarbital. Furthermore, the antagonistic activity against seizures induced by pentylenetetrazole of the compound 5m was also established, which suggested that compound 5m may exert anticonvulsant activity through g-aminobutyric acid (GABA)-mediated mechanisms.

  本文中，我们合成了一系列2-[(5-苯氧基-3-甲基-1-苯基-1H-吡唑-4-基)-亚甲基]酰肼羧酰胺，并利用最大电休克法评估了它们的抗惊厥活性。通过旋转棒试验测定了它们的中枢神经毒性。有趣的是，所有化合物在最大电休克试验中均显示出抗惊厥活性，且保护效果持久。其中，化合物5m表现出有前景的抗惊厥活性，其ED50为42.4 mg/kg，保护指数值为3.7，抗惊厥活性优于市场药物丙戊酸，但弱于苯巴比妥，并且安全性更高。此外，化合物5m对戊四氮诱导的惊厥也有拮抗活性，这表明化合物5m可能通过γ-氨基丁酸（GABA）介导的机制发挥抗惊厥作用。

  A series of pyrazolyl thiosemicarbazone derivatives were synthesized and evaluated for their anticonvulsant activity using the maximal electroshock (MES) method. Interestingly, all compounds prepared showed long duration of protection effect in the MES screens. Among them, compound 5b was considered as the most promising one with an $ED_50}$ value of 47.3 mg/kg, and a PI value of 4.8, which was superior to phenobarbital and valproate in the aspect of safety. Furthermore, compound 5b showed protection against seizures induced by pentylenetetrazole suggesting that compound 5b may exert anticonvulsant activity through GABA-mediated mechanisms.

  A new series of twenty four derivatives of pyrano[3,2-c]chromene IVa-x bearing 1H-pyrazole were synthesized by a one pot, base-catalyzed cyclocondensation reaction of 1H-pyrazole-4-carbaldehyde Ia-l, malononitrile II and 4-hydroxycoumarin IIIa-b. All the synthesized compounds were characterized by elemental analysis, FT-IR, 1H NMR and 13C NMR spectral data. All the synthesized compounds were screened against six bacterial pathogens, namely B. subtilis, C. tetani, S. pneumoniae, S. typhi, V. cholerae, E. coli and for antifungal activity against two fungal pathogens, A. fumigatus and C. albicans using the broth microdilution MIC method. Some of the compounds were found to be equipotent or more potent than commercial drugs against most of employed strains, as evident from the screening data.
