Synthetases' Achilles' heel? Selective inhibition of bacterial aminoacyl tRNA synthetases was previously accomplished by using aminoacyl sulfamoyladenosines and substituting aryltetrazole moieties for the adenine heterocycle. While these compounds did not prove successful in vivo, conjugation to peptidic Trojan horses or siderophore drug conjugate (SDC) transport modules envisaged improved uptake.
合成器的致命弱点?选择性抑制细菌氨酰基tRNA合成酶是通过使用氨酰基氨磺酰腺苷和用芳基四唑部分取代腺嘌呤杂环来实现的。尽管这些化合物在体内未证明成功,但与肽型特洛伊木马或铁载体药物共轭物(SDC)转运模块的结合可改善摄取。
