Abstract: Structure–activity relationships of the 3,5-diamino-piperidinyl triazine series, a novel class of bacterial translation inhibitors, are described. Optimization was focused on the triazine C-4 position in which aromatic substituents that contained electron-withdrawing groups led to potent inhibitors. The initial lack of antibacterial activity was correlated with poor cellular penetration. Whole cell antibacterial activity was achieved by linking additional aromatic moieties at the triazine C-4 position. [Copyright &y& Elsevier]

Abstract: Translation inhibitors of the 3,5-diamino-piperidine series act as aminoglycoside mimetics that inhibit bacterial growth. Here we show antibacterial SAR in the presence and absence of serum with a particular focus toward Pseudomonas aeruginosa. [Copyright &y& Elsevier]

Abstract: Aminoglycoside antibiotics target an internal RNA loop within the bacterial ribosomal decoding site. Here, we describe the synthesis and SAR of novel 3,5-diamino-piperidine derivatives as aminoglycoside mimetics, and show they act as inhibitors of bacterial translation and growth.
