Spectroscopic investigations and electronic transitions, topology studies, and biological assay of a potent antimicrobial compound: 2-amino-pyrimidine benzoic acid

The derivatives of benzoic acid, a claimed anti-fungal agent, are physiologically active components of vitamin B-complex. Signals in a heavily deshielded area is found using nuclear magnetic resonance analysis. In optimized geometry, the result reveals that nitrogen and oxygen are responsible for transfer of charge within the ring system wherein increases the bond length. Broadening and red shifting, which result from vibrational assignments, show the strength of intermolecular hydrogen bonds. Topological analysis like atoms in molecules, reduced density gradient graph that demonstrates favorable findings The electron localized function and localized orbital locator analysis are helpful when a site displays a strong distribution of electrons as a result of having the presence of a covalent bond, a lone pair of electrons, or a nuclear shell there. Findings of in vitro tests for antimicrobial activity clearly show that all two strains’ activity and inhibition both rise as compound concentrations climb. The title chemical may be verified to block antimicrobial activity and be a pesticide using molecular docking, in vitro antimicrobial activity, and qualities of a drug’s resemblance.

作为一种据称具有抗真菌活性的物质，苯甲酸衍生物是维生素B复合物的生理活性组分。通过核磁共振（Nuclear Magnetic Resonance, NMR）分析，可在高去屏蔽区域观测到特征信号峰。在优化后的几何构型下，结果表明氮原子与氧原子是环系内电荷转移的核心介导因素，该过程会导致键长增加。由振动指认所产生的峰宽化与红移现象，可反映分子间氢键的强度。诸如分子中的原子（Atoms in Molecules, AIM）理论、可呈现积极结果的约化密度梯度图谱，以及电子定域化函数（Electron Localized Function, ELF）与定域轨道定位器（Localized Orbital Locator, LOL）分析等手段，当某一区域因存在共价键、孤对电子或核壳层而呈现强电子分布时，均可发挥有效辅助作用。抗菌活性体外测试结果清晰显示，随着受试化合物浓度升高，两种菌株的活性与抑制率均同步上升。通过分子对接、体外抗菌活性实验以及类药性评价，可验证该标题化合物能够阻断抗菌活性，且具备作为农药的应用潜质。
