The molecule consists of two fused ring systems (Sys1 and Sys2) connected through a carbonyl linkage (-C(=O)-).

Sys1 is composed of a benzene ring fused to a five-membered carbocycle.
- The five-membered ring is fully saturated except at the two fusion junctions with the benzene.
- At the carbon of the five-membered ring that is not a fusion carbon and not adjacent to the fusion carbons, this position bears two methyl groups (gem-dimethyl substitution).

Sys2 is a benzene ring fused to a pyrrole.
- The pyrrole nitrogen is located adjacent to the fusion junction.
- This nitrogen carries a straight n-hexyl chain (six-carbon straight line).

These two systems are joined via a carbonyl bridge (-C(=O)-):
- On Sys1, the carbonyl connects to a benzene carbon meta to the fusion junctions.
- On Sys2, the carbonyl connects to the pyrrole carbon that is meta to the ring nitrogen and adjacent to the fusion junction.
