Three new isoaigialones, A, B, and C (1–3), along with aigialone (4), were isolated from the crude EtOAc extract of a Phaeoacremonium sp., an endophytic fungus obtained from the leaves of Senna spectabilis. The structures of these compounds were elucidated based on the analysis of spectroscopic data. Compounds 2 and 4 were active against the phytopathogenic fungi Cladosporium cladosporioides and C. sphaerospermum. This is the first report of metabolites produced by an Phaeoacremonium sp., associated with S. spectabilis.

由番泻叶的内生真菌Phaeoacremonium sp。生产的内酯衍生物

三个新的isoaigialones，A，B，和C（1 - 3）中，用aigialone（沿4），是从一个的粗乙酸乙酯提取物中分离Phaeoacremonium SP，从叶子上得到的内生真菌。美丽决明。根据光谱数据分析阐明了这些化合物的结构。化合物2和4对植物致病真菌Cladosporium cladosporioides和C. sphaerospermum具有活性。这是由Phaeoacremonium sp。产生的代谢产物与壮观链球菌相关的首次报道。
