Abstract

A series of 4-(piperidin-4-yl)-1-hydroxypyrazole (4-PHP) 3- or 5-imidazolyl substituted analogues have been designed, synthesized, and characterized pharmacologically. All analogues showed binding affinities in the low micro- to low nanomolar range at native rat GABAA receptors and were found to be antagonists at the human α1β2γ 2s receptor. The structure-activity relationship of the compound series demonstrates distinct differences in size and architecture of previously discovered cavities in the vicinity of the 4-PHP scaffold in the orthosteric binding site.
