Introduction to 3-cyclohexylpiperidin-2-one (CAS No. 50549-23-0)

3-cyclohexylpiperidin-2-one, identified by the Chemical Abstracts Service Number (CAS No.) 50549-23-0, is a significant compound in the realm of pharmaceutical chemistry and medicinal research. This heterocyclic organic compound belongs to the piperidine class, characterized by a six-membered ring containing one nitrogen atom. The presence of a cyclohexyl substituent at the 3-position and a carbonyl group at the 2-position imparts unique chemical and pharmacological properties, making it a valuable scaffold for drug discovery and development.

The structural motif of 3-cyclohexylpiperidin-2-one combines the favorable pharmacokinetic properties of piperidine derivatives with the steric and electronic effects of the cyclohexyl group. This combination has been exploited in the design of novel therapeutic agents, particularly in the treatment of neurological and cardiovascular disorders. The compound’s ability to interact with biological targets such as enzymes and receptors is influenced by its rigid cyclohexyl ring, which can enhance binding affinity and selectivity.

Recent advancements in computational chemistry and molecular modeling have highlighted the potential of 3-cyclohexylpiperidin-2-one as a key intermediate in the synthesis of bioactive molecules. Studies have demonstrated its utility in generating derivatives with enhanced solubility, metabolic stability, and target engagement. For instance, modifications at the 3-position or introduction of additional functional groups have been shown to modulate activity against specific biological pathways.
