meridianins A, B, C, and E from the Antarctic tunicate Synoicum sp. In the process of verifying the structure of these compounds it was noted that the physical data reported for meridianins bore a striking resemblance to that of psammopemmins. The psammopemmins are alkaloids bearing similar structures to the meridianins, but reported from the Antarctic sponge Psammopemma sp. To verify the structure originally
我们从南极被膜类植物Synoicum sp中分离了子午线素A,B,C和E。在验证这些化合物的结构的过程中,应注意所报告的子午线的物理数据与psammopemmins的惊人相似。psammopemmmmins是具有与子午线相似结构的生物碱,但据南极海绵Psammopemma sp。报道。为了验证最初提出的针对沙眼氨苄青霉素A的结构,合成了该化合物。通过比较1 H和13个与meridianin A的报告和合成psammopemmin A的C NMR数据,我们推断psammopemmin A的正确的结构分离自Psammopemma藻。实际上就是子午线A
