The structure and activity of the pseudodisaccharide core found in aminoglycoside antibiotics was probed with a series of synthetic analogues in which the position of amino groups was varied around the glucopyranose ring. The naturally occurring structure neamine was the best in the series according to assays for in vitro RNA binding and antibiotic activity. With this result in hand, neamine was used
在氨基糖苷类抗生素中发现的假二糖核心的结构和活性是用一系列合成类似物探测的,其中氨基的位置在吡喃葡萄糖环周围发生变化。根据体外 RNA 结合和抗生素活性的测定,天然存在的结构 neamine 是该系列中最好的。有了这个结果,neamine 被用作合成新抗生素的共同核心结构,评估其与大肠杆菌 16S A 位点核糖体 RNA 模型的结合、体外蛋白质合成抑制和抗生素活性。RNA结合的分析揭示了RNA结合的相对亲和力和特异性与抗菌功效之间的一些相关性。然而,相关性不是线性的。这一结果促使我们开发了体外翻译试验,以更好地了解氨基糖苷类-RNA 的相互作用。体外翻译抑制与抗生素活性之间的线性相关性...
