The known antibiotic and cytotoxic compounds griseorhodin A (1) and griseorhodin C (2) were produced in solid culture by Streptomyces puniceus AB10, which was isolated from the leaf-cutter ant Acromyrmex rugosus rugosus. Their absolute configurations were unambiguously established as 6S,6aR,7S,8S and 6R,6aR,7S,8R, respectively, using vibrational circular dichroism (VCD) and density functional theory (DFT) calculations.
