  Novel Inhibitors of Staphyloxanthin Virulence Factor in Comparison with Linezolid and Vancomycin versus Methicillin-Resistant, Linezolid-Resistant, and Vancomycin-Intermediate Staphylococcus aureus Infections in Vivo

  摘要：

  Our previous work (Wang et al. J. Med. Chem. 2016, 59, 4831-4848) revealed that effective benzocycloalkane-derived staphyloxanthin inhibitors against methicillin-resistant Staphylococcus aureus (S. aureus) infections were accompanied by poor water solubility and high hERG inhibition and dosages (preadministration). In this study, 92 chroman and coumaran derivatives as novel inhibitors have been addressed for overcoming deficiencies above. Derivatives 69 and 105 displayed excellent pigment inhibitory activities and low hERG inhibition, along with improvement of solubility by salt type selection. The broad and significantly potent antibacterial spectra of 69 and 105 were displayed first with normal administration in the livers and hearts in mice against pigmented S. aureus Newman, Mu50 (vancomycin-intermediate S. aureus), and NRS271 (linezolid-resistant S. aureus), compared with linezolid and vancomycin. In summary, both 69 and 105 have the potential to be developed as good antibacterial candidates targeting virulence factors.

• The use of 1,2-O-isopropylidene-α-d-xylofuranose as a chiral auxiliary in asymmetric cyclopropanation reactions

  1,2-O-isopropylidene-d-xylofuranose, as a chiral auxiliary, is described. The Simmons–Smith cyclopropanation reaction of the corresponding alkenylidene derivatives with CH2I2/ZnEt2, in different reaction conditions, took place with high stereoselectivity. The diastereomeric excess in each case depended on the solvent and the temperature used in the reaction. The absolute configuration of the new stereogenic

  描述了衍生自作为手性助剂的1,2 - O-异亚丙基-d-木呋喃糖的环丙基亚甲基缩醛的立体选择性合成。在不同的反应条件下，相应的链烯基衍生物与CH 2 I 2 / ZnEt 2的Simmons-Smith环丙烷化反应具有很高的立体选择性。在每种情况下，非对映异构体过量取决于反应中所用的溶剂和温度。通过手性助剂的环丙烷部分的酸水解确定了形成的新的立体异构中心的绝对构型，该手性助剂也被回收了。
