The G protein-gated inwardly-rectifying potassium channels (GIRK, KO) are a family of inward-rectifying potassium channels, and there is significant evidence supporting the roles of GIRKs in a number of physiological processes and as potential targets for numerous indications. Previously reported urea containing molecules as GIRK1/2 preferring activators have had significant pharmacokinetic (PK) liabilities. Here we report a novel series of 1H-pyrazolo-5yl-2-phenylacetamides in an effort to improve upon the PK properties. This series of compounds display nanomolar potency as GIRK1/2 activators with improved brain distribution (rodent K-p > 0.6).
