摘要

从真菌 Curvularia moringae JKYM-KR4 中分离出了七种新的多酮类化合物[moringols I-VII (1-7)]、一种新的生物碱[moringamine I (8)]和七种已知化合物（9-15）。新化合物的平面化学结构和相对构型是通过高分辨率质谱、一维和二维核磁共振光谱以及利用计算的 13C 核磁共振化学位移进行 DP4+ 分析而阐明的。对于吗啉醇 I 和 II（1 和 2），其平面化学结构和相对构型已通过 X 射线晶体学得到证实。1-6 和 8 的绝对构型是通过 ECD 计算确定的。在分离出的化合物中，松油醇（14）能中度抑制 HT-29 细胞的增殖。

Chemical structures of polyketides and alkaloids isolated from a culture of fungus Curvularia moringae

Seven new polyketides [moringols I–VII (1–7)], a new alkaloid [moringamine I (8)], and seven known compounds (9–15) were isolated from the fungus Curvularia moringae JKYM-KR4. The planar chemical structures and relative configurations of the new compounds were elucidated by high-resolution mass spectrometry, 1D and 2D NMR spectroscopy, and DP4+ analysis using the calculated ¹³C NMR chemical shifts. For moringols I and II (1 and 2), the planar chemical structures and relative configurations were confirmed using X-ray crystallography. The absolute configurations of 1–6 and 8 were determined by ECD calculations. Among the isolated compounds, terpestacin (14) moderately inhibited the proliferation of HT-29 cells.
