Synthesis and Structure–Activity Relationships of N-Benzyl Phenethylamines as 5-HT2A/2C Agonists
摘要:
N-Benzyl substitution of 5-HT2A receptor agonists of the phenethylamine structural class of psychedelics (such as 4-bromo-2,5-dimethoxyphenethylamine, often referred to as 2C-B) confer a significant increase in binding affinity as well as functional activity of the receptor. We have prepared a series of 48 compounds with structural variations in both the phenethylamine and N-benzyl part of the molecule to determine the effects on receptor binding affinity and functional activity at 5-HT2A and 5-HT2c receptors. The compounds generally had high affinity for the 5-HT2A receptor with 8b having the highest affinity at 0.29 nM but with several other compounds also exhibiting subnanomolar binding affinities. The functional activity of the compounds was distributed over a wider range with lb being the most potent at 0.074 nM. Most of the compounds exhibited low to moderate selectivity (1- to 40-fold) for the 5-HT2A receptor in the binding assays, although one compound 6b showed an impressive 100-fold selectivity for the 5-HT2A receptor. In the functional assay, selectivity was generally higher with lb being more than 400-fold selective for the 5-HT2A receptor.
NOVEL SULFOXIMINE ACTIVATORS OF SEROTONIN RECEPTORS
摘要:
Methods of treating a stress-related disease or disorder such as PTSD and mood/depressive disorder, inducing neurite outgrowth, or inducing structural neuroplasticity, comprising administering to a subject a composition comprising an effective amount of a compound that does not have an agonist activity on 5-HT2Aserotonin receptor are disclosed. Also disclosed are pharmaceutical compositions comprising compound not having an agonist activity on 5-HT2Aserotonin receptor and a pharmaceutically acceptable carrier.
