Structural studies of new macrolide antibiotics, shurimycins A and B.
The structures of new antibiotics, shurimycins A and B produced by Streptomyces hygroscopicus A1491, were elucidated from the physico-chemical properties, 2D NMR techniques and chemical degradation experiments to be 36-membered macrolides related to azalomycins, scopafungin and guanidylfungins. Shurimycins were active against fungi and Gram-positive bacteria.
