Four new metabolites (1-4) were isolated from mycelium of Aspergillus terreus IFO 6123 producing asterriquinone (ARQ). The structures of 1 and 2 were shown to be 3,6-bis[1-(1,1-dimethyl-2-propenyl)-1H-indol-3-yl]-furo[3,2-b]furan- 2,5-dione (asterridinone) and 2,5-bis[1-(1,1-dimethyl-2-propenyl)-1H-indol-3- yl]-3-acetoxy-6-hydroxy-2,5-cyclohexadiene-1,4-dione (ARQ monoacetate), respectively, by the
从产曲霉菌的土生曲霉IFO 6123菌丝体中分离出四个新的代谢物(1-4)。1和2的结构显示为3,6-双[1-(1,1-二甲基-2-丙烯基)-1H-吲哚-3-基]-呋喃[3,2-b]呋喃-2 ,5-二酮(甾体酮)和2,5-双[1-(1,1-二甲基-2-丙烯基)-1H-吲哚-3-基] -3-乙酰氧基-6-羟基-2,5-环己二烯-1,4-二酮(ARQ单乙酸酯)分别由化学和光谱数据组成。化合物3和4已通过已知的星形醌异构体2- [1-(1,1-二甲基-2-丙烯基)-1H-吲哚-3-基] -5- [2-(3-甲基-2-丁烯基) )-1H-吲哚-3-基] -3,6-二羟基-2,5-环己二烯-1,4-二酮(isoARQ)和2,5-双[2-(3-甲基-2-丁烯基)- 1H-吲哚-3-基] -3,6-二羟基-2,5-环己二烯-1,4-二酮(neoARQ)。
