Pyridine is a six-membered heterocyclic compound containing one nitrogen heteroatom. Pyridine and piperidine are the most frequently occurring heterocyclic building blocks in drug molecules. According to incomplete statistics, there are currently more than 180 drugs containing pyridine or piperidine structure that have been marketed, nearly 1/5 of the drugs approved for marketing in recent years contain these two structures.

Pyridine is a basic heterocyclic organic compound with the chemical formula C5H5N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom. It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish-like smell.
Pyrrolidine, also known as tetrahydropyrrole, is a saturated five-membered heterocyclic ring, which is miscible with water. Pyrrolidine exists in many alkaloids and drug molecules, such as kappa opioids, antagonists of dopamine D4 receptors, and HIV reverse transcriptase inhibitors.
Oxadiazoles are a class of heterocyclic aromatic compounds with the molecular formula C2H2N2O, which have special biological activities and thermodynamic properties. Five-membered heterocyclic moieties composed of three or two heteroatoms are of great interest to researchers because these compounds show significant therapeutic potential. These heterocycles can serve as a building block for the development of novel molecular structures.
Cyclohexane is an organic compound with a chemical formula C6H12. It is a colorless liquid with a pungent odor, insoluble in water, and soluble in most organic solvents such as ethanol, ether, benzene, and acetone. Cyclohexyl fragments are a common structure in both natural and synthetic drugs. It can be used as both core structure and part of achiral side chain.
