N-[2-(Pyridin-4-ylcarbonyl)hydrazinyl]carbonothioyl}furan-2-carboxamide and its complexes with Ni(II), Co(II), Cu(II), Zn(II) and Mn(II) ions have been synthesized. The structure of the synthesized compounds was elucidated by elemental analysis, conductivity measurements, UV-visible, FT-IR, 1H NMR, powder XRD and thermal analysis studies. Most of metal complexes have exhibit thermal degradation between 80-750 °C and the powder X-rays diffraction data suggest that all the synthesized metal complexes were in nano crystalline phase. The computational molecular docking has been studied using Hex molecular modeling package version 8.2. The three dimensional structure of E. coli MurBenzyme (PDB code 2MBR) was used in microbial activity. The metal complexes showed comparable E total values with the standard drug tetracycline. The antioxidant and antimicrobial activity of prepared compounds indicate agreeable results versus bacterial strains three Gram-positive bacteria; S. aureus, S. pyogenes and P. acnes and three Gram-negative bacteria; E. coli, K. terrigena and K. pneumonia. The antifungal activity gave good results against fungal strains C. albicans, C. neoformans and Trichosporon.
合成了 N-[2-(吡啶-4-基羰基)肼基]碳硫酰基}呋喃-2-甲酰胺及其与 Ni(II)、Co(II)、Cu(II)、Zn(II) 和 Mn(II) 离子的配合物。通过元素分析、电导率测量、紫外可见光、傅立叶变换红外光谱、1H NMR、粉末 X 射线衍射和热分析研究,阐明了合成化合物的结构。大多数金属复合物在 80-750 ℃ 之间出现热降解,粉末 X 射线衍射数据表明,所有合成的金属复合物都呈纳米结晶相。使用 Hex 分子建模软件包 8.2 版进行了分子对接计算研究。大肠杆菌 MurBenzyme 的三维结构(PDB 代码 2MBR)被用于微生物活性研究。金属复合物显示出了与标准药物四环素相当的 E 总值。所制备化合物的抗氧化和抗菌活性表明,它们对三种革兰氏阳性菌(金黄色葡萄球菌、化脓性葡萄球菌和痤疮丙酸杆菌)和三种革兰氏阴性菌(大肠杆菌、大肠杆菌和肺炎双球菌)的抗菌效果良好。抗真菌活性对白僵菌、新变形杆菌和三孢子菌等真菌菌株有很好的效果。
