Abstract:
The structures of octacosamicins A and B, two new antifungal antibiotics, were studied by spectrometries and chemical modifications. The 2D NMR techniques including 1H-detected heteronuclear multiple bond correlation method were successfully applied to this study. These antibiotics have unique linear chain structure possessing N-hydroxyguanidyl group at the terminal.
