title: Actinopyrones A, B and C, new physiologically active substances. II. Physico-chemical properties and chemical structures.
abstract: The structure of physiologically active substances, actinopyrones A, B and C, produced by Streptomyces pactum S12538 were determined on the basis of their spectral and chemical character. These substances were structurally related to piericidin A1.
