The spectral analysis of methyl 3‐methyl‐2‐((pyridin‐2‐ylcarbonyl)amino)benzoate (L1) is investigated using the FT‐IR, 1H and 13C NMR and UV‐Vis analysis using the DFT methods (B3LYP and PBEPBE) with the 6‐311+G(d,p) basis set. The Hirshfeld and fingerprint analyses were used to investigate the intermolecular interactions in the crystal structure. The vibrational wavenumbers were fulfilled in the form of potential energy distribution. The absorption wavelengths, excitation energies, and oscillator strengths for the UV‐Vis were performed by the TD‐DFT calculations in the gas phase and DMSO, chloroform solvents with the major contributions to the electronic transitions. The chemical shifts values of the NMR in CDCl3 solvent were computed using the gauge independent atomic orbital (GIAO) method and compared with the experimental data. The NLO properties such as mean polarizability, the anisotropy of the polarizability and the mean first‐order hyperpolarizability were computed by using the finite field method. The high β values (2.617×10−30 and 6.481×10−30 esu using the B3LYP and PBEPBE) indicate that a title compound is an attractive object for NLO properties. Reduced density gradient was also given to study the weak interaction, strong attraction, and strong repulsion interactions of the molecule. Molecular docking studies with different receptors (3IX3, 3UW8, and 1P93) have been performed to demonstrate that L1 has good anti‐inflammatory and analgesic activity.

高效的消炎镇痛活性的光谱学,Hirshfeld表面分析和分子对接研究3-甲基-2-甲基((吡啶-2-基羰基)氨基)苯甲酸甲酯

使用FT-IR,1 H和13 C NMR以及DFT方法的UV-Vis分析(B3LYP )研究了3-甲基-2-((吡啶-2-基羰基)氨基)苯甲酸甲酯(L1)的光谱分析和PBEPBE)与6-311 + G(d,p)基础集。Hirshfeld和指纹分析用于研究晶体结构中的分子间相互作用。振动波数以势能分布的形式实现。UV-Vis的吸收波长,激发能和振荡器强度是通过TD-DFT计算在气相和DMSO,氯仿溶剂中进行的,这对电子跃迁起了主要作用。CDCl 3中NMR的化学位移值使用量规无关原子轨道(GIAO)方法计算溶剂,并与实验数据进行比较。使用有限域方法计算了NLO性质,例如平均极化率,极化率的各向异性和平均一阶超极化率。高的β值(使用B3LYP和PBEPBE的2.617 ×10 -30和6.481×10 -30 esu)表明标题化合物是NLO性质的诱人对象。还提供了降低的密度梯度来研究分子的弱相互作用,强吸引和强排斥相互作用。已经进行了与不同受体(3IX3、3UW8和1P93)的分子对接研究,以证明L1具有良好的抗炎和镇痛活性。
