  日期：2006.9

  The syntheses of a diverse set of 2-aryl-4-quinolone derivatives were achieved by exposing corresponding acylated 2'aminoacetophenones to microwave irradiation in the presence of NaOH. The microwave accelerated cyclizations were complete within 10-22 min at 120 degrees C giving 57-95% isolated yields. (c) 2006 Elsevier Ltd. All rights reserved.
• C-2 phenyl replacements to obtain potent quinoline-based <i>Staphylococcus aureus</i> NorA inhibitors

  NorA is the most studied efflux pump of Staphylococcus aureus and is responsible for high level resistance towards fluoroquinolone drugs. Although along the years many NorA efflux pump inhibitors (EPIs) have been reported, poor information is available about structure-activity relationship (SAR) around their nuclei and reliability of data supported by robust assays proving NorA inhibition. In this regard, we focussed efforts on the 2-phenylquinoline as a promising chemotype to develop potent NorA EPIs. Herein, we report SAR studies about the introduction of different aryl moieties on the quinoline C-2 position. The new derivative 37a showed an improved EPI activity (16-fold) with respect to the starting hit 1. Moreover, compound 37a exhibited a high potential in time-kill curves when combined with ciprofloxacin against SA-1199B (norA+). Also, 37a exhibited poor non-specific effect on bacterial membrane polarisation and showed an improvement in terms of "selectivity index" in comparison to 1.
