  Antibacterial activity of chalcones, hydrazones and oxadiazoles against methicillin-resistant Staphylococcus aureus

  摘要：

  The increase in antibiotic resistance due to multiple factors has encouraged the search for new compounds which are active against multidrug-resistant pathogens. In this context, chalcones, dihydrochalcones, hydrazones and oxadiazoles were tested against Staphylococcus aureus ATCC 25923 and methicillin-resistant S. aureus (MRSA) isolates, which were obtained from clinical laboratories and were characterized as MRSA using traditional and molecular methods. Among 65 tested compounds, two chalcones, one dihydrochalcone and two hydrazones were active against MRSA. Based on the minimal inhibitory concentration and cytotoxicity, hydrazones provided a better selectivity index than chalcones. Active hydrazones are promising antibiotic-like substances and they should be the subject of further microbiological studies. (C) 2011 Elsevier Ltd. All rights reserved.

  芳烃钌 (II) 催化的无受体脱氢偶联策略简便合成 N-酰基腙

  摘要：

  已经描述了使用芳烃钌 (II) 配合物通过容易获得的醇和苯并酰肼 (R 2 CONHNH 2 ) 的无受体脱氢偶联，轻松催化一锅法合成N-酰基腙。使用钌催化剂将醇与各种苯并酰肼偶联提供了广泛的N-酰基腙具有良好至极好的收率（63–93%；32 个例子）。本协议提供了高选择性的腙，没有任何烷基化产物，并耐受一系列官能团。对照实验表明，该机制通过醇的无受体脱氢进行，氢和水是唯一的副产物。克级合成说明了本策略的有用性。

  A facile catalytic one-pot synthesis of N-acylhydrazones via acceptorless dehydrogenative coupling of readily available alcohols and benzohydrazides (R2CONHNH2) using arene ruthenium (II) complexes has been described. The coupling of alcohols with various benzohydrazides using ruthenium catalysts provide a wide range of N-acylhydrazones in good to excellent yields (63–93%; 32 examples). The present
