The N, N'-(1,2-phenylene) bis (1- (4- chlorophenyl) methanimine) (CS4) was synthesized and characterized by infrared (IR), absorption (UV-vis) and NMR (H and C) spectral analyses. The structural parameters, vibrational frequencies, potential energy and the distribution analysis (PED) were calculated by using DFT with the basis set of B3LYP/cc-pVDZ and these spectral values were compared to the experimental values. HOMO and LUMO studied were performed in order to understand the stability and biological activity of the compound. The most reactive sites on the compound were investigated by utilizing MEP energy surface and Fukui function descriptor with the natural population analysis (NPA) of the charges. The study of the natural bond orbitals (NBO) reveals the delocalization of the intramolecular interaction of the charges in the compound. Additionally, topological investigations (ELF, LOL), determination of thermodynamic parameters and noncovalent interaction (NCI) study by using topology (RDG) analysis were also carried out. Finally, the molecular docking and molecular dynamics simulations was carried out by examining against glycosylphosphatidylinositol phospholipase D inhibitor receptor for distinct protein targets (3MZG).
合成了N,N'-(1,2-亚苯基)双(1-(4-氯苯基)甲亚胺)(CS4),并通过红外(IR)、吸收(紫外-可见)和核磁共振(H和C)光谱分析对其进行了表征。使用B3LYP/cc-pVDZ基组通过密度泛函理论(DFT)计算了结构参数、振动频率、势能和分布分析(PED),并将这些光谱值与实验值进行了比较。进行了最高占据分子轨道(HOMO)和最低未占据分子轨道(LUMO)的研究,以了解该化合物的稳定性和生物活性。利用分子静电势(MEP)能量表面和福井函数描述符以及电荷的自然布居分析(NPA)研究了该化合物上最具反应活性的位点。自然键轨道(NBO)的研究揭示了化合物中电荷分子内相互作用的离域。此外,还进行了拓扑研究(扩展拉格朗日电子密度函数(ELF)、拉普拉斯算子对电子密度的分析(LOL))、热力学参数的测定以及通过拓扑(简化密度梯度(RDG))分析进行的非共价相互作用(NCI)研究。最后,针对不同的蛋白质靶点(3MZG),通过与糖基磷脂酰肌醇磷脂酶D抑制剂受体进行对接,开展了分子对接和分子动力学模拟。
