Staphylococcus aureus (MRSA) agents from a molecular hybridization approach. The representative compound 19 showed an MIC = 1 μg/mL against a panel of MRSA clinical isolates as it possessed comparable in vitro activities to that of vancomycin. Moreover, compound 19 also exhibited MIC = 1 μg/mL activities against a recent identified Z172 MRSA strain (vancomycin-intermediate and daptomycin-nonsusceptible
通过分子杂交方法合成了一系列带有吲哚环的N-取代咔唑类似物,作为抗甲氧西林的金黄色葡萄球菌(MRSA)药物。代表性化合物19对一组MRSA临床分离株显示MIC = 1μg/ mL,因为它具有与万古霉素相当的体外活性。此外,化合物19还对最近鉴定出的Z172 MRSA菌株(万古霉素中和达托霉素不敏感表型)和耐万古霉素的粪肠球菌表现出MIC = 1μg/ mL活性(VRE)应变。在MRSA(4N216)致死性感染的小鼠模型中,以20 mg / kg的剂量静脉内施用单剂量的化合物19后,观察到75%的存活率。考虑到它们针对不同的MRSA分离物和VRE菌株的等效活性,数据强调了设计的杂交系列对于开发新的N-取代咔唑作为潜在的抗MRSA试剂的重要性。
