Abstract
As part of our efforts to develop better therapies for the treatment of cognitive impairment associated with Alzheimer's disease and Schizophrenia, we have focused our research towards 5-HT6 receptor (5-HT6R) in order to identify potent and selective ligands for this purpose. Herein, we report the synthesis, structure activity relationship and biological evaluation of a novel series of 3-(arylsulfonyl)-8-(piperidin-4-yl amino)quinoline derivatives, as 5-HT6 receptor (5-HT6R) antagonists. In this work, we have shown that moving from aryl sulfonamide platform to biaryl sulfone platform retains the 5-HT6R affinity when tested in vitro in cell based reporter gene functional assay.
