摘要

通过植物化学研究，获得了3个新的酰胺类衍生物(alteralalaloids A-C, 1-3)和3个已知的生物碱(4-6)。这些化合物的结构通过核磁共振波谱和HRESIMS数据得到了证实。此外，利用单晶x射线衍射分析确定了1的绝对构型。化合物1-3属于自然界中未发现的一类酰胺衍生物，具有丁基部分和酰胺基团相同的特征信号。对这些分离的化合物进行了细胞毒活性测试。

Three new amide derivatives from the fungus Alternaria brassicicola

Three new amide derivatives (alteralkaloids A–C, 1–3) and three known alkaloids (4–6) were afforded after phytochemical investigation of fungus Alternaria brassicicola. The structures of these compounds were confirmed by NMR spectroscopic and HRESIMS data. Furthermore, the absolute configuration of 1 was determined using the single-crystal X-ray diffraction analysis. Compounds 1–3 belong to a class of amide derivatives that have not been found in nature before, sharing the same characteristic signals of the butyl moiety and amide group. These isolated compounds mentioned above were tested for the cytotoxic activity.

期刊介绍： Natural Products and Bioprospecting serves as an international forum for essential research on natural products and focuses on, but is not limited to, the following aspects: Natural products: isolation and structure elucidation Natural products: synthesis Biological evaluation of biologically active natural products Bioorganic and medicinal chemistry Biosynthesis and microbiological transformation Fermentation and plant tissue cultures Bioprospecting of natural products from natural resources All research articles published in this journal have undergone rigorous peer review. In addition to original research articles, Natural Products and Bioprospecting publishes reviews and short communications, aiming to rapidly disseminate the research results of timely interest, and comprehensive reviews of emerging topics in all the areas of natural products. It is also an open access journal, which provides free access to its articles to anyone, anywhere.
