A series of 4-(1-substituted piperidin-4-yloxy) benzamides and 6-(1-substituted piperidin-4-yloxy)-3,4-dihydro-2H-isoquinolin-1-one derivatives have been synthesized and tested for their binding affinity towards H3 receptor. Most of these synthesized compounds have displayed potent binding affinity for H3 receptor when tested in in vitro binding assay. Preliminary SAR studies, functional activity, pharmacokinetic profile and efficacy profile constitute the subject matter of this communication.
Keywords: Histamine H(3) receptor; Pharmacokinetic profile; Receptor occupancy; SAR.
