The two new indole alkaloids 2-amino-1,5-dihydro-5-(1H-indol-3-ylmethyl)-4H-imidazol-4-one (1), 2-amino-5-[(6-bromo-1H-indol-3-yl)methyl]-3,5-dihydro-3-methyl-4H-imidazol-4-one (2), and auramine (3) have been isolated from the sea anemone Heteractis aurora. Both indole alkaloids were synthesized for the confirmation of the structures. Homarine (4), along with uracil (5), hypoxanthine (6), and inosine (7) have been obtained from Octopus cyanea.
2-氨基-1,5-二氢-5-(1H-吲哚-3-基甲基)-4H-咪唑-4-酮（1）、2-氨基-5-[(6-溴-1H-吲哚-3-基)甲基]-3,5-二氢-3-甲基-4H-咪唑-4-酮（2）以及金胺（3）。为了确定结构，合成了这两种吲哚生物碱。从蓝环章鱼中获得了高甜菜碱（4）以及尿嘧啶（5）、次黄嘌呤（6）和肌苷（7）。
