Novel 4-(Piperidin-4-yl)-1-hydroxypyrazoles as γ-Aminobutyric AcidA Receptor Ligands: Synthesis, Pharmacology, and Structure−Activity Relationships
摘要:
A series of substituted 1-hydroxypyrazole analogues of the GABA(A) receptor partial agonist 5-(4-piperidyl)-3-isoxazolol (4-PIOL) have been synthesized and pharmacologically characterized. Several of the analogues displayed K-i in the low nanomolar range at the native GABAA receptors and potent antagonism of the alpha(1)beta(2)gamma(2) receptor. It appears that several regions situated in proximity to the core of the orthosteric binding site of the GABA(A) receptor are able to accommodate large hydrophobic substituents.
