In an effort to develop new antimicrobial agents, a novel series of 2-[4-(substituted phenyl)amino]methyl)-1H-isoindole-1,3(2H)-dione derivatives 2-17a,b was synthesized starting from 2-([4-(bromoacetyl)phenyl]amino}methyl)-1H-isoindole-1,3 (2H)-dione 1 by introducing different hetero-cyclic moieties, such as thiazole, thiazolidinone, azetidinone, furan and pyrazole. The structures of all the synthesized compounds have been elucidated by means of IR, 1H NMR, mass spectroscopic data and elemental analysis. Most of the synthesized compounds were screened for their antimicrobial activity by means of agar well diffusion assay while the minimal inhibitory concentrations of the active compounds were then assessed utilizing broth dilution method. Derivative 2-[(4-[(1,3-Dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl] amino} phenyl)-2-oxoethyl]propane dinitrile 15 was the most potent compound.
为了开发新型抗菌剂,从2-([4-(溴乙酰基)苯基]氨基}甲基)-1H-异吲哚-1,3(2H)-二酮1出发,通过引入不同杂环基团,如噻唑、噻唑烷二酮、氮杂环丁烷二酮、呋喃和吡唑,合成了一系列新型2-[4-(取代苯基)氨基]甲基}-1H-异吲哚-1,3(2H)-二酮衍生物2-17a,b。所有合成化合物的结构已通过IR、1H NMR、质谱数据和元素分析进行阐明。大多数合成化合物通过琼脂孔扩散试验进行抗菌活性筛选,然后利用肉汤稀释法评估活性化合物的最低抑制浓度。其中,2-[(4-[(1,3-二氧-1,3-二氢-2H-异吲哚-2-基)甲基]氨基}苯基)-2-氧乙基]丙烷二腈15是活性最强的化合物。
