dimeric cationic anthraquinone analogs (CAAs) with potent antimicrobial activities against a broad range of fungi and bacteria were developed. These compounds were prepared in 2–3 steps with high overall yield and possess alkyl chain, azole, quinone, and quaternary ammonium complexes (QACs). In vitro biological evaluations reveal prominent inhibitory activities of lead compounds against several drug-susceptible
开发了一系列合成的二聚阳离子蒽醌类似物(CAA),它们对多种真菌和细菌具有有效的抗菌活性。这些化合物分2-3步制备,具有较高的总收率,并具有烷基链,唑,醌和季铵盐配合物(QAC)。体外生物学评估显示,铅化合物对多种药物敏感和耐药真菌和细菌菌株具有显着的抑制活性,包括MRSA,VRE,白色念珠菌和黄曲霉。作用模式研究表明,合成的二聚CAA可以破坏真菌的膜完整性。计算研究表明,可能的设计可以使QAC恢复抗药性细菌的活性。癌细胞系SKOV-3中的细胞毒性试验表明,先导化合物对真菌和细菌的选择性毒性高于人类细胞。
