A new antitumor antibiotic, LL-C10037 alpha was isolated from the fermentation filtrate of a Streptomyces by adsorption, partition and reverse phase column chromatography. Its chemical structure was determined by 1H NMR, 13C NMR, UV, IR and mass spectral data. LL-C10037 alpha is a gamma-aminoepoxysemiquinone and is related to the epoxyguinone class of antibiotics.
