    design of new antibiotics. Drug repurposing is a promising strategy for expanding the antibiotic repertoire. In this study, we repurpose the clinically approved anticancer agent cisplatin into a targeted antibiotic by conjugating its Pt(IV) prodrug to enterobactin (Ent), a triscatecholate siderophore employed by Enterobacteriaceae for iron (Fe) acquisition. The l-Ent-Pt(IV) conjugate (l-EP) exhibits

  • Investigation of Siderophore–Platinum(IV) Conjugates Reveals Differing Antibacterial Activity and DNA Damage Depending on the Platinum Cargo

    innovative strategies to combat bacterial pathogens, particularly Gram-negative strains, which pose a significant challenge due to their outer membrane permeability barrier. In this study, we repurpose clinically approved anticancer agents as targeted antibacterials. We report two new siderophore–platinum(IV) conjugates, both of which consist of an oxaliplatin-based Pt(IV) prodrug (oxPt(IV)) conjugated to enterobactin
    细菌感染的威胁日益严重,加上有效抗生素的不断减少,迫切需要采取创新策略来对抗细菌病原体,特别是革兰氏阴性菌株,这些菌株由于其外膜渗透性屏障而构成重大挑战。在这项研究中,我们将临床批准的抗癌药物重新用作靶向抗菌药物。我们报告了两种新的载体-(IV)缀合物,两者均由与肠杆菌素(Ent)缀合的基于奥沙利铂的Pt(IV)前药(oxPt(IV))组成,肠杆菌素是肠杆菌科用于获取的三儿茶酚载体。我们证明l / d -Ent-oxPt(IV)( l / d -EOP)选择性地递送到大肠杆菌细胞质中,实现靶向抗菌活性,形成丝状形态,并导致细菌细胞对Pt的吸收增强,但减少人体细胞对 Pt 的吸收。与奥沙利铂和l -EOP 相比, d -EOP 表现出增强的效力,这主要归因于其非天然载体部分的内在抗菌活性。为了进一步阐明 Ent–Pt(IV) 缀合物的抗菌活性,我们探测了l / d -EOP 和之前报道的基于顺铂的缀合物l
  • Enterobactin-Mediated Delivery of β-Lactam Antibiotics Enhances Antibacterial Activity against Pathogenic <i>Escherichia coli</i>
    作者:Tengfei Zheng、Elizabeth M. Nolan
    DOI:10.1021/ja503911p
    日期:2014.7.9
    The design, synthesis, and characterization of enterobactin antibiotic conjugates, hereafter Ent-Amp/Amx, where the beta-lactam antibiotics ampicillin (Amp) and amoxicillin (Amx) are linked to a monofunctionalized enterobactin scaffold via a stable poly(ethylene glycol) linker are reported. Under conditions of iron limitation, these siderophore-modified antibiotics provide enhanced antibacterial activity against Escherichia coli strains, including uropathogenic E. coli CFT073 and UTI89, enterohemorrhagic E. coli O157:H7, and enterotoxigenic E. coli O78:H11, compared to the parent beta-lactams. Studies with E. coli K-12 derivatives defective in ferric enterobactin transport reveal that the enhanced antibacterial activity observed for this strain requires the outer membrane ferric enterobactin transporter FepA. A remarkable 1000-fold decrease in minimum inhibitory concentration (MIC) value is observed for uropathogenic E. coli CFT073 relative to Amp/Amx, and time-kill kinetic studies demonstrate that Ent-Amp/Amx kill this strain more rapidly at 10-fold lower concentrations than the parent antibiotics. Moreover, Ent-Amp and Ent-Amx selectively kill E. coli CFT073 co-cultured with other bacterial species such as Staphylococcus aureus, and Ent-Amp exhibits low cytotoxicity against human T84 intestinal cells in both the apo and iron-bound forms. These studies demonstrate that the native enterobactin platform provides a means to effectively deliver antibacterial cargo across the outer membrane permeability barrier of Gram-negative pathogens utilizing enterobactin for iron acquisition.
