their microbicidal and anti-pathogenic features. The largest spectrum of the antibacterial activity is evidenced for the nitro- (2b) and hydroxy- (5b) N-oxides, followed by the amino-N-oxide (3b). Density functional theory (DFT) modeling of the molecular structure and frontier molecular orbitals, i.e. highest occupied/lowest unoccupied molecular orbital (HOMO/LUMO), is accomplished by using the GAMESS
摘要 针对 12 种细菌和真菌菌株评估了一系列 9-取代的 1,2,3,4,5,6,7,8-八氢吖啶-N(10)-氧化物的杀微生物和抗病原体特性。硝基-(2b) 和羟基-(5b) N-氧化物的抗菌活性谱最大,其次是氨基-N-氧化物(3b)。分子结构和前沿分子轨道的密度泛函理论 (DFT) 建模,即最高占据/最低未占据分子轨道 (HOMO/LUMO),是通过在 M11/ktzvp 理论水平使用 GAMESS 2012 软件完成的,以便找到它们结构和电子参数。我们表明分子的平面性和吸电子基团的存在是其抗菌活性的优势。最后,
