Abstract

A NRPKS gene cluster cic in Aspergillus nidulans was activated by overexpression of the pathway-specific transcriptional factor CicD. Large-scale fermentation and chemical investigation of the engineered strain A. nidulans A1145/cicD led to the discovery of two new isoindolone-amino acid adducts, isoleucylcichorine () and leucylcichorine (), along with three known derivatives. The structures of the new compounds were clearly determined by nuclear magnetic resonance (NMR) analysis, high-resolution electrospray ionization mass spectrometry (HRESIMS), and electronic circular dichroism (ECD) calculations. This study revealed that the overexpression of the pathway-specific transcriptional factor represents a promising approach for the discovery of new natural products in fungi.

途径特异性转录因子CicD的过度表达导致在细粒曲霉中发现新的植物毒素。
NRPKS基因簇cic通过过表达途径特异性转录因子CicD而被激活。对工程菌株A. nidulans A1145/cicD进行大规模发酵和化学研究,发现了两种新的异吲哚-氨基酸加合物,异亮氨酸环胆碱(1)和亮氨酸环胆碱(2),以及三种已知衍生物。通过核磁共振(NMR)分析、高分辨率电喷雾质谱(hresms)和电子圆二色性(ECD)计算,明确了新化合物的结构。这项研究表明,通路特异性转录因子的过表达代表了在真菌中发现新的天然产物的有希望的方法。
