Leukaemomycin-geblockte Mutanten desStreptomyces griseus und ihre Pigmente II. Neue 7-Hydroxy-bisanhydro-rhodomycinone aus der Mutante ZIMET 41707/1P

Abstract
Various blocked mutants were isolated from 3 leukaemomycin-producing strains IMET JA 3933, IMET JA 5142 and IMET JA 5570 of S. griseus by nitrosoguanidine and UV treatments. Among them, 1 class of 4 mutants ZIMET 43707/1P, IMET JA 5570/3P, IMET JA 5570/10P and IMET JA 5142/01Pl produced new blue and red pigments. Two red compounds designated 1PI and 1PII are the main components of the pigment complex produced by culture of the blocked mutant ZIMET 43707/1P. This paper describes the isolation of 1PI and 1PII; the spectral and physicochemical properties of these anthracyclinones and the elucidation of their structures are reported.
