  Structure–activity relationships of novel alkylides: 3-O-Arylalkyl clarithromycin derivatives with improved antibacterial activities

  摘要：

  A series of novel alkylides, possessing 3-O-arylallcyl group instead of 3-O-cladinose, were designed, synthesized and evaluated for in vitro antibacterial activities. The increased potency clearly ranked by the order of 3-O-(3-aryl-2-propargyl), 3-O-(3-aryl-E-prop-2-enyl), 3-O-(3-aryl-propyl), and 3-O-(3-aryl-Z-prop-1-enyl) groups. Some alkylides, exemplified by 7a, 10a, 21, 22, 26, 27 and 33, showed improved activities against inducible MLSB resistance and efflux resistance compared to the second-generation macrolides. Among them, 26 possessed comparable activities against erythromycin-susceptible Staphylococcus aureus, Streptococcus pneumoniae and Streptococcus pyogenes (MICs of 0.016-0.5 mu g/mL). Moreover, 26 displayed dramatically enhanced potency against both efflux resistant and inducibly MLSB resistant strains (MICs of 0.125-0.5 mu g/mL) resistant to clarithromycin and azithromycin (MICs of 1 >254 mu g/mL), independent of methicillin-susceptible and methicillin-resistant phenotypes.
