The title compound, CHNO, consists of three rings, , and , linked by amide bonds with the benzene rings and being inclined to the mean plane of the central benzene ring by 2.99 (18) and 4.57 (18)°, respectively. In the crystal, mol-ecules are linked N-H⋯O and C-H⋯O hydrogen bonds, forming fused (18), (30), (38) rings running along [0] and (37) and (15) rings along [001]. Hirshfeld analysis was undertaken to study the inter-molecular contacts in the crystal, showing that the most significant contacts are H⋯O/O⋯H (30.5%), H⋯C/C⋯H (28.2%) and H⋯H (29.0%). Two zones with positive (50.98 and 42.92 kcal mol) potentials and two zones with negative (-42.22 and -34.63 kcal mol) potentials promote the N-H⋯O inter-actions in the crystal. An evaluation of the mol-ecular coupling of the title compound and the protein with enzymatic properties known as human coagulation factor Xa (hfXa) showed the potential for coupling in three arrangements with a similar minimum binding energy, which differs by approximately 3 kcal mol from the value for the mol-ecule Apixaban, which was used as a positive control inhibitor. This suggests the title compound exhibits inhibitory activity.
标题化合物CHNO由三个环、和通过酰胺键相连,苯环和相对于中心苯环的平均平面分别倾斜2.99 (18)°和4.57 (18)°。在晶体中,分子通过N-H⋯O和C-H⋯O氢键相连,形成沿[0]方向延伸的稠合(18)、(30)、(38)环以及沿[001]方向的(37)和(15)环。进行了 Hirshfeld 分析以研究晶体中的分子间相互作用,结果表明最显著的相互作用是H⋯O/O⋯H (30.5%)、H⋯C/C⋯H (28.2%) 和H⋯H (29.0%)。两个具有正电势(50.98和42.92 kcal mol)的区域和两个具有负电势(-42.22和-34.63 kcal mol)的区域促进了晶体中的N-H⋯O相互作用。对标题化合物与具有人类凝血因子Xa (hfXa)酶活性的蛋白质的分子偶联评估表明,在三种排列方式下具有偶联潜力,其最小结合能相似,与用作阳性对照抑制剂的阿哌沙班分子的值相差约3 kcal mol。这表明标题化合物具有抑制活性。
