  Surprising Alteration of Antibacterial Activity of 5′′-Modified Neomycin against Resistant Bacteria

  摘要：

  A facile synthetic protocol for the production of neomycin B derivatives with various modifications at the 5 '' position has been developed. The structural activity relationship (SAR) against aminoglycoside resistant bacteria equipped with various aminoglycoside-modifying enzymes (AMEs) was investigated. Enzymatic and molecular modeling studies reveal that the superb substrate promiscuity of AMEs allows the resistant bacteria to cope with diverse structural modifications despite the observation that several derivatives show enhanced antibacterial activity compared to the parent neomycin. Surprisingly, when testing synthetic neomycin derivatives against other human pathogens, two leads exhibit prominent activity against both methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) that are known to exert a high level of resistance against clinically used aminoglycosides. These findings can be extremely useful in developing new aminoglycoside antibiotics against resistant bacteria. Our result also suggests that. new biological and antimicrobial activities can be obtained by chemical modifications of old drugs.

  摘要：

  固定在丙烯酸树脂（Novozyme®435）上的CAL-B（南极假丝酵母脂肪酶B）可平滑地催化带有炔丙基胺的炔丙基酰胺的甲酯的氨解。在同一反应容器中，这些炔丙基衍生物在Cu（I）催化的叠氮化物-炔烃环加成（CuAAC）点击反应中连续良好地转化为酰胺连接的1,2,3-三唑，其收率良好。
