A new indoloquinazoline alkaloid, ophiuroidine 1, having an indolo[2,1-b]quinazoline-6,12-dione skeleton, was isolated from the Caribbean ophiuroid, Ophiocoma riisei. The structure of 1 was determined as 4,8,9-trihydroxyindolo[2,1-b]quinazoline-6,12-dione from spectroscopic data. Ophiuroidine 1 is the first example of an indoloquinazoline alkaloid found in a marine invertebrate.
一种新的吲哚喹唑啉生物碱,邻氨基吡啶[ 1],具有吲哚[ 2,1 - b ]喹唑啉-6,12-二酮骨架,是从加勒比海蛇形拟南芥(Ophiocoma riisei)分离得到的。从光谱数据确定1的结构为4,8,9-三羟基吲哚[2,1- b ]喹唑啉-6,12-二酮。phiurouroidine 1是在海洋无脊椎动物中发现的吲哚喹唑啉生物碱的第一个实例。
