Structure of pamamycin-607, an aerial mycelium-inducing substance of Streptomyces alboniger

Abstract Pamamycin-607 with aerial mycelium-inducing activity has been isolated from Streptomyces alboniger , and its structure with the relative stereochemistry has been determined as a novel ionophore compound ( 1 ) on the basis of spectral analysis mainly by 2D 1 H 13 C and 1 H 1 H correlation NMR and NOE difference spectroscopy.
