摘要: 应用各种层析手段(Sephadex LH-20,硅胶Silica和RP-8柱层析),从海洋真菌发酵液中分离纯化了2个actinopyrone类化合物,结合多种波谱方法(HRESI-MS, 1D NMR, 2D NMR),确定了它们的结构为:actinopyrone A C. 利用NOESY试验确定了它们的相对构型,并根据HMBC数据纠正了这2个化合物C-21(H-21)位和C-22(H-22)位的化学位移.

Abstract: Two antibiotic compounds, actinopyrone A(1) and C (2) were separated from lyophilized culture broth of marine fungus Penicilliumsp. and their structures were elucidated with 1D and 2D NMR and HR-ESI-MS. The relative stereochemistry of compounds 1 and 2 was determined by analyzing the NMR NOESY data. Based on the NMR HMBC data, the erroneous chemical shifts of C-21 (H-21) and C-22 (H-22) reported in the literature were corrected.
