Three novel isoquinoline alkaloids, TMC-120A, B and C (1–3) have been isolated from a fermentation broth of Aspergillusustus (Bain.) Thom & Church TC 1118, a fungus isolated from rhizosphere of grass. Their structures were determined through extensive spectroscopic analyses and chemical studies. TMC-120s (1–3) are found to be the first furo[3,2-h]isoquinoline-type alkaloids isolated from natural sources
从曲霉(Bain。)Thom&Church TC 1118的发酵液中分离出了三种新型异喹啉生物碱TMC-120A,B和C(1-3),这是一种从草根际分离的真菌。它们的结构是通过广泛的光谱分析和化学研究确定的。TMC-120s(1-3)被发现是第一种从天然来源中分离出来的呋喃[3,2 - h ]异喹啉型生物碱。
