Erythromycins H and I, shunt metabolites of the clinically important antibacterial drug erythromycin A, have been isolated from the new actinomycete Actinopolyspora sp. YIM90600. A. sp. YIM90600 joins Saccharopolyspora erythraea and Aeromicrobium erythreum as only the third actinomycete reported capable of producing erythromycins. In addition to producing new erythromycins, A. sp. YIM90600, even under suboptimal conditions, is a high titer producer of erythromycin C. The presence of the C-14 hydroxyl moiety and the 6,18-epoxide in the 14-membered lactone nucleus of erythromycin H and the spiro-fused dipyran moiety of erythomycin I sheds new insight into the size and structural diversity of erythromycin analog libraries accessible by combinatorial biosynthesis.
