The Chem3D structures shown in this and following figures are low-energy conformers identified by a Monte Carlo conformation search performed in Macromodel 6.0 using the MM2 force field. No competing low energy conformers within the range of 2 kcal/mol were defined. Some hydrogens have been hidden for clarity. For this conformation search, the side chain was simulated as a methyl group.

Stereochemical descriptors for C-17, C-18, and C-19 were based on an arbitrary assignment of C-14 as S. For ease of reading, we have abbreviated 17R, 18R, 19R as RRR (etc.) in the discussion of the side chain stereochemistry.

We had observed this color change during purification of the initial fermentations. As the change in TLC behavior between 1 and 3 is almost imperceptible, we originally attributed the color change to decomposition of a minor component.

Antibacterial activity was determined using the standard discdiffusion assay. Neomangicol B (50 μg) caused a 10 mm zone of inhibition during a 24-h incubation period, compared to the standard gentamycin (10μg), which also resulted in a 10 mm zone of inhibition.
