AbstractIn the present study, a series of amide derivatives of 4-nitro-l-phenylalanine were synthesized with good yield from 4-nitro-l-phenylalanine and substituted anilines using propylphosphonic anhydride (T3P®) as coupling reagent and were characterized through the IR, LC–MS, 1H and 13C NMR spectral studies. The isolated products were screened for antimicrobial and antioxidant activities. Some of
摘要在本研究中,一系列4-硝基-的酰胺衍生物的升-苯丙氨酸,用良好的产率从4-硝基合成升-苯丙氨酸和取代使用丙基膦酸酐(T3P苯胺®)作为偶联试剂和通过IR进行了表征,LC-MS,1 H和13 C NMR光谱研究。筛选分离的产物的抗微生物和抗氧化活性。一些化合物显示了小孢子菌石膏活性或对白色念珠菌有活性,也有一些化合物表现出抗菌活性。所得化合物筛选出抗氧化剂活性,其对DPPH清除和ABTS测定方法显示出良好的活性,而其他化合物具有中等的活性。一些酰胺化合物充当与Fe 2+离子的金属螯合配体。 图形概要
