6-Methyl-7H,8H,9H-[1,2,4]triazolo[4,3-b][1,2,4]triazepin-8-onehas been synthesized, characterized by spectroscopic techniques (FT-IR, 1H and 13C NMR) and finally the structure was confirmed by single crystal X-ray diffraction studies. In the title molecule, C6H7N5O, the 7-membered ring adopts a bowl-like conformation. In the crystal, the molecules form stacks along the c-axis direction through offset
合成了 6-Methyl-7H,8H,9H-[1,2,4]triazolo[4,3-b][1,2,4]triazepin-8-one,通过光谱技术(FT-IR、1H和 13C NMR),最后通过单晶 X 射线衍射研究证实了结构。在标题分子 C6H7N5O 中,7 元环采用碗状构象。在晶体中,分子通过5元环与CH···N氢键之间的偏移π-堆叠相互作用沿c轴方向形成堆叠。叠层通过NH···N、CH···O和CH···N氢键的组合缔合。此外,Hirshfeld 表面分析揭示了分子相互作用的性质,指纹图提供了有关每个单独分子接触对表面的百分比贡献的信息。此外,由于其生物学意义,基于结构活性关系(SAR)分析发现了靶分子腺苷A1受体,并进一步进行了分子对接和分子动力学分析,以了解该分子在腺苷A1受体系统中的结合相互作用和稳定性。此外,对游离化合物和活性位点化合物(单点DFT)进行了密度泛函理论(DF
