氨酰胺类化合物是一类具有广泛生物活性的吡咯并喹啉类生物碱。通过挖掘链霉菌DCA 2648基因组,发现了一个与amm BGC在基因内容和遗传结构上高度同源的生物合成基因簇(BGC),从而发现了一个新的AMM同源物亚家族,命名为ammosesters(艾姆斯)。艾姆斯具有C-4a甲酯,不同于AMM特有的C-4a酰胺官能团,并对广谱的人癌细胞系表现出适度的细胞毒性,扩展了吡咯并喹啉家族天然产物的结构-活性关系。ame和amm BGC的比较分析支持使用支架肽作为天然产物的吡咯并喹啉家族的生物合成的新兴范例。AME和AMM生物合成分别通过进化途径特异性Ame 24 O-甲基转移酶和Amm 20酰胺合成酶而从共同的中间体偏离。这些发现肯定会激发未来的努力,模仿自然的组合生物合成策略,天然产品的结构多样性。
The ammosamides (AMMs) are a family of pyrroloquinoline alkaloids that exhibits a wide variety of bioactivities. A biosynthetic gene cluster (BGC) that is highly homologous in both gene content and genetic organization to the amm BGC was identified by mining the Streptomyces uncialis DCA2648 genome, leading to the discovery of a sub-family of new AMM congeners, named ammosesters (AMEs). The AMEs feature a C-4a methyl ester, differing from the C-4a amide functional group characteristic to AMMs, and exhibit modest cytotoxicity against a broad spectrum of human cancer cell lines, expanding the structure–activity relationship for the pyrroloquinoline family of natural products. Comparative analysis of the ame and amm BGCs supports the use of a scaffold peptide as an emerging paradigm for the biosynthesis of the pyrroloquinoline family of natural products. AME and AMM biosynthesis diverges from a common intermediate by evolving the pathway-specific Ame24 O-methyltransferase and Amm20 amide synthetase, respectively. These findings will surely inspire future efforts to mimic Nature's combinatorial biosynthetic strategies for natural product structural diversity.
