The 3-[1-(3-benzoylphenyl)ethyl]-1H-isochromen-1-one, 2 and their thio-analogues 3-[1-(3-benzoylphenyl)ethyl]-1H-isochromen-1-thione, 3 and 3-1-[3-(benzothioyl) phenyl]ethyl}-1H-isochromen-1-one, 5 were successfully obtained in good yield and purity from anti-inflammatory drug ketoprofen, 1 and its thio analogue, 4. The compounds were successfully characterized by FT-IR, MASS, 1HNMR and 13CNMR spectral techniques. The in vitro anti-inflammatory and anti-oxidant screening revealed that 3-[1-(3-benzoylphenyl) ethyl]-1H-isochromen-1-one, 2 possesses better anti-oxidant and anti-inflammatory activity whereas 3-(1-(3-benzoylphenyl)ethyl)-1H-isochromene-1-thione, 3 and 3-(1-(3-benzothioyl) phenyl] ethyl}-1H-isochromen-1-one, 5 showed moderate anti-oxidant activity in comparison to ketoprofen.
从消炎药酮洛芬 1 及其硫代类似物 4 中成功获得了 3-[1-(3-苯甲酰基苯基)乙基]-1H-异苯并吡喃-1-酮 2 及其硫代类似物 3-[1-(3-苯甲酰基苯基)乙基]-1H-异苯并吡喃-1-硫酮 3 和 3-1-[3-(苯并硫酰基)苯基]乙基}-1H-异苯并吡喃-1-酮 5,收率和纯度都很高。这些化合物成功地通过傅立叶变换红外光谱、质谱、1HNMR 和 13CNMR 光谱技术进行了表征。体外抗炎和抗氧化筛选结果表明,3-[1-(3-苯甲酰基苯基)乙基]-1H-异苯并吡喃-1-酮(2)具有更好的抗氧化和抗炎活性,而 3-(1-(3-苯甲酰基苯基)乙基)-1H-异苯并吡喃-1-硫酮(3)和 3-(1-(3-苯甲硫酰基)苯基)乙基}-1H-异苯并吡喃-1-酮(5)与酮洛芬相比,显示出中等程度的抗氧化活性。
