The structures of octacosamicins A and B, two new antifungal antibiotics, were studied by spectrometries and chemical modifications. The 2D NMR techniques including 1Hdetected 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.
