铜 (ii) 与 3-(2-pyridyl)-4,5-dihydro-1H-pyrazoles 的配合物:合成、结构和电化学研究
摘要:
通过适当的有机配体与CuCl2·2H2O反应,得到了三种新的铜(ii)配合物与3-(2-吡啶基)-4,5-二氢-1H-吡唑配体。配合物的结构由X射线衍射确定。所有配合物的分子式均可写为2(L·MCl2)(L为有机配体)。任一铜离子的配位多面体是一个扭曲的三角双锥体,由两个 N 原子(来自吡唑啉和吡啶环)和一个轴向和两个桥接氯阴离子组成。采用循环伏安法研究了1,5-二苯基-3-(2-吡啶基)-4,5-二氢-1H-吡唑及其CuII配合物的电化学行为;提出了它们的电氧化和电还原机理。

Design, synthesis, and in-silico studies of pyrazolylpyridine analogues: A futuristic antibacterial contender against coagulase positive superbug-MRSA
overcome this complication, this work aimed at synthesis of pyrazolylpyridine analogs as potential anti-superbug agents and using a simple synthetic protocol. The synthesized pyrazolylpyridine analogs were characterized using spectroscopic techniques like FTIR, NMR, and mass spectroscopy. All synthesized pyrazolylpyridine analogs were evaluated for the in-vitro antibacterial activity. The antibacterial
在 MRSA 感染宿主期间的凝血级联反应中,葡萄球菌被阻塞在纤维蛋白凝块网内,宿主组织很难清除这些病原体,也使病原体引起致命的败血症。为了克服这种复杂性,这项工作旨在合成吡唑基吡啶类似物作为潜在的抗超级细菌剂,并使用简单的合成方案。使用光谱技术如 FTIR、NMR 和质谱对合成的吡唑基吡啶类似物进行表征。评价了所有合成的吡唑基吡啶类似物的体外抗菌活性。通过细胞内容物泄漏和钾流出量的测量进一步证实了抗菌活性。采用结晶紫染料技术对抗生物膜活性进行了定性和定量研究。使用分子对接测试了化合物与 1NU7 和 1MWT 蛋白的结合能力,并将进一步的类似物暴露于动态模拟中。还检查了合成的化合物的 ADMET 分析。据观察,与标准药物万古霉素的 3(ag) 类似物相比,4(ag) 系列显示出潜在的抗菌活性。发现 4e 的 MIC 值为 30±0.4 µg/mL,并且还显示出优异的抗生物膜活性。揭示的数据与葡萄凝酶
3-(2-Pyridyl)-2-pyrazoline derivatives: novel fluorescent probes for Zn2+ ion
Spectroscopic studies revealed that 3-(2-pyridyl)-2-pyrazoline derivatives have rather strong affinity toward divalent transition metal ions. but have almost no interaction with alkali and alkaline-earth metal ions. In the case of the 5-(4-cyanophenyl) derivative, enhancement of the fluorescence intensity was observed upon addition of the Zn2+ ion, while most of other transition metal ions caused complete quenching.
