characterization of 3,5-diamino-piperidinyl triazines (DAPT), a novel translation inhibitor class that targets bacterial rRNA and exhibits broad-spectrum antibacterial activity. DAPT compounds were designed as structural mimetics of aminoglycoside antibiotics which bind to the bacterial ribosomal decoding site and thereby interfere with translational fidelity. We found that DAPT compounds bind to oligonucleotide
我们报告的3,5-二
氨基-
哌啶基三嗪(DAPT),针对细菌rRNA的新型翻译
抑制剂类,并表现出广谱抗菌活性的结构指导的发现,合成和初始表征。DAPT化合物被设计为
氨基糖苷类抗生素的结构模拟物,可与细菌
核糖体解码位点结合,从而干扰翻译保真度。我们发现DAPT化合物与解码位点RNA的寡核苷酸模型结合,在体外抑制翻译,并在体内诱导翻译错误整合,这与
核糖体解码位点的作用机理相符。新型DAPT抗菌剂可抑制革兰氏阳性和革兰氏阴性细菌(包括呼吸道病原体
铜绿假单胞菌)的生长,并且对人类
细胞系显示低毒性。
