Reaction Steps
The solids obtained were chromatographed on Brinkmann 60F254 silica gel thin layer plates using an 80:20 toluene:methanol solvent system. The first band to elute was shown by thin layer chromatography to be a complex inactive mixture. The second band gave a characteristic pinkish red zone at about Rf =0.75. This fraction was also inactive and was found to comprise mainly η-pyrromycinone. The third fraction to elute gave a single zone with Rf ~0.3. This was determined to be musettamycin and was highly active when tested on both the L1210 and P388 mouse leukemia systems. The final band to elute gave a zone of Rf ~0.3 and comprised mainly marcellomycin but also a minor proportion of rudolphomycin. This component exhibited high activity when tested on L1210 and P388 mouse leukemia systems.
