  Platform to Discover Protease-Activated Antibiotics and Application to Siderophore–Antibiotic Conjugates

  摘要：

  Here we present a platform for discovery of protease-activated prodrugs and apply it to antibiotics that target Gram-negative bacteria. Because cleavable linkers for prodrugs had not been developed for bacterial proteases, we used substrate phage to discover substrates for proteases found in the bacterial periplasm. Rather than focusing on a single protease, we used a periplasmic extract of E. coli to find sequences with the greatest susceptibility to the endogenous mixture of periplasmic proteases. Using a fluorescence assay, candidate sequences were evaluated to identify substrates that release native amine-containing payloads. We next designed conjugates consisting of (1) an N-terminal siderophore to facilitate uptake, (2) a protease-cleavable linker, and (3) an amine-containing antibiotic. Using this strategy, we converted daptomycin-which by itself is active only against Gram-positive bacteria-into an antibiotic capable of targeting Gram-negative Acinetobacter species. We similarly demonstrated siderophore-facilitated delivery of oxazolidinone and macrolide antibiotics into a number of Gram-negative species. These results illustrate this platform's utility for development of protease-activated prodrugs, including Trojan horse antibiotics.

  摘要：

  儿茶酚是许多金属螯合物的成分，包括由微生物分泌的天然存在的铁(III)螯合剂——侧胞素。儿茶酚衍生物在有机介质中溶解性差，合成含儿茶酚的分子需要使用具有更好有机溶解性的保护儿茶酚前体。因此，我们开发了2,2-二苯基-苯并[1,3]二噁烷-4-羧酸五氟苯酯。这种活化酯可以与一种氨基功能化的骨架反应，生成在二苯基-苯并二噁烷基团形式下保护的儿茶酚功能团。合成结束时，儿茶酚可以通过三氟乙酸（TFA）去保护。该策略用于合成两种带有末端炔基扩展的儿茶酚化合物。这两种化合物被证明能促进大肠杆菌和铜绿假单胞菌对铁的摄取。这两种化合物适合用作抗生素特洛伊木马方法中的载体，因为它们可以通过胡根偶极体1,3-环加成与叠氮功能化抗生素结合。
