Reinvestigation of the secondary metabolites from the marine mangrove fungus Aigialus parvus BCC 5311 led to the isolation of six new nonaketide metabolites, aigialomycins F (4) and G (5a/5b), 7′,8′-dihydroaigialospirol (7), 4′-deoxy-7′,8′-dihydroaigialospirol (8), and rearranged macrolides 9 and 10, along with six previously described compounds, hypothemycin (1), aigialomycins A (2) and B (3), aigialospirol
对来自海洋红树林真菌Aigialus parvus BCC 5311的次级代谢产物的重新研究导致分离出6种新的非肽代谢产物,aigialomycins F(4)和G(5a / 5b),7',8'-dihydroaigialospirol(7),4' -deoxy-7',8'-dihydroaigialospirol(8)和重排大环内酯9和10,以及六个先前描述的化合物,hypomycin(1),aigialomycins A(2)和B(3),aigialospirol(6),4 - ö -demethylhypothemycin(11),和aigialone(12)。通过结合化学方法对NMR光谱和质谱数据进行分析,阐明了新化合物的结构。
