The molecule is built on a pyridine ring, an aromatic six-membered ring containing one nitrogen atom. 

From the carbon adjacent to the ring nitrogen, a linear eight-atom side chain extends. All bonds in this chain are single bonds. All atoms of the chain are carbons except for position 3, which is a nitrogen atom. Numbering proceeds outward from the carbon attached to the pyridine ring.

There are three additional substituents on this chain. 
- The nitrogen at position 3 and the carbon at position 7, each carry a methyl group (-CH3). 
- At carbon 6, which is stereogenic, the configuration is R, and this carbon carries a primary amine substituent (-NH2).
