A new purine, 1,3-dimethyl-8-oxoisoguanine (2) was isolated from the New Zealand ascidian Pseudodistoma cereum. The structure of 2 was elucidated by the use of standard spectroscopic techniques, including natural abundance 1H-15N 2D NMR.
从新西兰海鞘Pseudodistoma cereum中分离出一种新的嘌呤,即1,3 - 二甲基 - 8 - 氧代异鸟嘌呤(2)。通过使用包括天然丰度1H - 15N二维核磁共振在内的标准光谱技术阐明了2的结构。
