Avilamycin is an antibiotic complex produced by cultures of the organism Streptomyces viridochromogenes, strain NRRL 2860. These compounds belong to the orthosomycin family of antibiotics. Structural composition of the major avilamycins and several minor avilamycins are known. Nine additional minor avilamycins, designated F through N, have been isolated via semi-preparative silica gel or reverse-phase high performance liquid chromatography with final purification using a reverse-phase column loading solvent switching technique. 1H NMR and mass spectroscopy, negative ion fast atom bombardment (neg FAB) and electron impact, were used to structurally identify the avilamycins. All of the compounds were microbiologically
active and similar in structure to other known avilamycins.
