Structures of monodontamides A, B, C, D, E, and F, six new alkaloids isolated from the marine gastropod mollusc Monodonta labio (Linné)
摘要:
Six new alkaloids monodontamides A (1), B (2), C (3), D (4), E (5), and F (6) were isolated from the marine gastropod mollusc Monodonta labio (Linne). The structures of monodontamides were established on the basis of spectral data and unambiguous synthesis. Monodontamides exhibited weak inhibitory activity against a serine protease.
