Bacterial defense mechanisms have evolved to protect bacteria against predation by nematodes, predatory bacteria, or amoebae. We identified novel bacterial alkaloids (pyreudiones A–D) that protect the producer, Pseudomonas fluorescens HKI0770, against amoebal predation. Isolation, structure elucidation, total synthesis, and a proposed biosynthetic pathway for these structures are presented. The generation
细菌防御机制已得到发展,可以保护细菌免受线虫,掠食性细菌或变形虫的侵害。我们确定了新型细菌生物碱(pyreudiones A–D)可以保护生产者荧光假单胞菌HKI0770免受变形虫的侵害。介绍了这些结构的分离,结构阐明,总合成以及拟议的生物合成途径。的产生荧光假单胞菌基因缺失突变体不能呈现的细菌的可食用各种土栖变形虫的农产品pyreudiones。
