In the course of our chemical screening program for new secondary metabolites, we isolated new compounds JBIR-37 (1) and -38 (2) from a culture broth of the marine sponge-derived fungus, Acremonium sp. SpF080624G1f01. The structures of 1 and 2 were determined to be di- and mono-O-β-d-glucopyranosyloxy-4-(1,1-dimethyl-2-propenyl)benzene on the basis of extensive NMR and MS spectroscopic data, respectively.
在对新的次生代谢物进行化学筛选的过程中,我们从海洋海绵真菌 Acremonium sp. SpF080624G1f01 的培养液中分离出了新化合物 JBIR-37(1)和 -38(2)。根据大量的核磁共振和质谱数据,我们确定了 1 和 2 的结构分别为二-O-β-d-吡喃葡萄糖氧基-4-(1,1-二甲基-2-丙烯基)苯和单-O-β-d-吡喃葡萄糖氧基-4-(1,1-二甲基-2-丙烯基)苯。
