title: [New anthracycline antibiotics taurimycins A and B produced by a Str. tauricus No. 7036-1 culture].
abstract: Taurimycins A and B are new anthracycline antibiotics belonging to the group of glycosides. They were isolated from the mycelium of culture 7036-1 classified with Str. tauricus. The empiral formula of taurimycin A is C14H51O16N,M+813. The empirical formula of taurimycin B is C41H49O16N,M+811. The absorption maxima in the UV spectra of the antibiotics (in alcohol solutions) were observed at 235, 257, 292, 466, 482, 494, 515 and 527 nm. The IR spectra showed absorption bands at 3450, 2945, 2870, 1740 and 1610 cm-1. Hydrolysis of the antibiotics with hydrochloric acid resulted in formation of an aglycone identified as epsilon-pyrromycinone.
