of the fermentation broth of DPJ-0019 has yielded the first monomeric benzo[b]fluorene isolated from this species, (−)-homoseongomycin (13). (−)-Homoseongomycin (13) is related to the known natural product seongomycin (10), which is co-produced with the monomeric diazofluorenes known as the kinamycins. We describe the synthesis of the isotopically labeled derivative homoseongomycin-d5 (14), via the
被称为lomaiviticins的二聚重氮芴是由海洋细菌Salinispora pacifica DPJ-0019生产的。对DPJ-0019发酵液的研究得出了从该物种中分离出的第一个单体苯并[ b ]芴,(-)-同型霉素(13)。(-)-同型霉素(13)与已知的天然产物Seongomycin(10)有关,该产物与被称为kinamycins的单体重氮芴共同生产。我们通过重氮芴“ prelomaiviticin- d 5 ”(12)的中间体描述了同位素标记的衍生物hooseseongomycin- d 5(14)的合成。)。我们的研究确定(-)-同型霉素(13)可能来自前麦金古霉素(11),并表明13和10是分别在lomaiviticin和kinamycin生物合成中的分流或解毒代谢产物。
