the action of several bacterial resistance mechanisms that deactivate tobramycin and chloramphenicol. This study demonstrates that covalently linking two identical or different ribosome-targeting antibiotics may lead to (i) a broader spectrum of antimicrobial activity, (ii) improved inhibition of bacterial translation properties compared to that of the parent antibiotics, and (iii) reduction in the
在这项研究中,我们描述了不同核糖体靶向抗生素的三种完整结构的全套同二聚体和异二聚体的合成:妥布霉素、克林霉素和氯霉素。评估了二聚体结构生物活性的几个方面,包括抗微生物活性、体外细菌蛋白质翻译的抑制,以及二聚体化对使妥布霉素和氯霉素失活的几种细菌耐药机制的作用的影响。这项研究表明,共价连接两种相同或不同的靶向核糖体的抗生素可能会导致 (i) 更广泛的抗菌活性,(ii) 与母体抗生素相比,改善对细菌翻译特性的抑制,
