  Synthesis and structure-activity relationship of C-3 benzoyloxymethyl cephalosporins exhibiting anti-MRSA activities

  摘要：

  A series of cephalosporins bearing C-3 benzoyloxymethyl groups were prepared and evaluated for their anti-MRSA activity and plasma stability. They exhibit excellent in vitro activity (MIC = 0.06 similar to 2 mu g/mL) against MRSA and excellent stability in human plasma. (C) 1997 Elsevier Science Ltd.

  featuring carboxylate co-ligands are prepared and characterized. The best catalysts show very high activities for copolymerization using cyclohexene oxide (TOF = 8880 h−1, 20 bar CO2, 120 °C, 0.01 mol% catalyst loading) or cyclopentene oxide. All the catalysts are highly active in the low pressure regime and specifically at 1 bar pressure CO2. The polymerization kinetics are analysed using in situ spectroscopy

  二氧化碳和环氧化物的开环共聚是制备脂肪族聚碳酸酯和增加CO 2价值的有用手段。最近，第一个异双核 Zn( II )/Mg( II ) 催化剂表现出比任一同双核类似物更高的活性 ( J. Am. Chem. Soc. 2015 , 137, 15078–15081)。基于这一初步发现，本文制备并表征了八种具有羧酸盐共配体的新型 Zn( II )/Mg( II ) 异双核催化剂。最好的催化剂在使用环己烯氧化物（TOF = 8880 h -1、20 bar CO 2、120 °C、0.01 mol% 催化剂负载量）或环戊烯氧化物时表现出非常高的共聚活性。所有催化剂在低压状态下特别是在1巴压力CO 2下均具有高活性。使用原位光谱和等分技术分析聚合动力学：速率定律总体上是二阶的，催化剂和环氧化物浓度都具有一阶依赖性，二氧化碳压力为零阶。比较催化剂系列的伪一级速率系数值，差异主要归因于对引发速率的影响
