The molecule features an isoquinoline core, where a benzene and a pyridine ring are fused through two shared atoms, with the pyridine nitrogen positioned meta to one of the shared atoms.
At another carbon that is also meta to the pyridine nitrogen and ortho to the other shared atom, a carbon is attached. This carbon belongs to an imine group and also carries a hydroxyl group, forming -C(OH)=N-. The imine nitrogen is further bonded to a three-carbon straight chain that terminates with a nitrogen atom substituted with two n-propyl groups.
