Galnon is a low-molecular weight galanin receptor ligand, with affinity towards the three galanin receptors in the micromolar range. Galnon is of interest as a drug candidate due to its stability and ability to pass the blood-brain barrier. Like galanin, galnon has also been shown to affect various physiological functions; however, occasionally galanin and galnon act in opposing ways. Since its introduction in 2002, galnon has been characterized to inhibit seizures, decrease feeding behaviour, diminish physical signs of opiate withdrawal and to alleviate heat-hyperalgesic response to partial sciatic nerve injury. In this review, we will summarize what is known about galnon to date.

UI	MeSH Term	Description	Entries
D008024	Ligands	A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed)	Ligand
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D003374	Coumarins	Synthetic or naturally occurring substances related to coumarin, the delta-lactone of coumarinic acid.	1,2-Benzopyrone Derivatives,1,2-Benzopyrones,Coumarin Derivative,Coumarine,1,2-Benzo-Pyrones,Benzopyran-2-ones,Coumarin Derivatives,Coumarines,1,2 Benzo Pyrones,1,2 Benzopyrone Derivatives,1,2 Benzopyrones,Benzopyran 2 ones,Derivative, Coumarin,Derivatives, 1,2-Benzopyrone,Derivatives, Coumarin
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D044088	Receptors, Galanin	A family of G-protein-coupled receptors that are specific for GALANIN and galanin peptides. They are generally considered to be coupled to the GI, INHIBITORY G-PROTEIN to meditate the neurological effects of galanin. Several subtypes of galanin receptors occur with differing specificities for the full length galanin, galanin peptide fragments, and galanin-like peptide.
