Overexpression of the PbrlaeA gene of the fungus HDN-12-143 resulted in the isolation of four compounds including fumigatin chlorohydrin (), whose configuration has not been reported before, and one new compound iso-fumigatin chlorohydrin (). All structures including absolute configurations were elucidated on the basis of comprehensive spectroscopic data, C NMR calculations, and ECD calculations. Compounds and exhibited cytotoxic activity against HL-60 with IC of 18.63 and 24.83 μM.
真菌HDN-12-143的PbrlaeA基因过表达导致分离出四种化合物，包括氯代烟曲霉毒素（其构型此前未见报道）和一种新化合物异氯代烟曲霉毒素。所有结构包括绝对构型均通过综合光谱数据、碳核磁共振计算和电子圆二色计算得以阐明。化合物 和 对HL-60细胞表现出细胞毒性活性，IC50分别为18.63和24.83 μM。
