Deltamycins, new macrolide antibiotics. II. Isolation and physicochemical properties.
The new macrolide antibiotics were isolated by silica gel chromatography. They showed a UV absorption maximum at 240 nm. Deltamycins A1, A2 and A3 were demonstrated to be new macrolide antibiotics on the basis of their physicochemical properties whereas deltamycin A4 was identified as carbomycin A.
