The present study describes the discovery and characterization of a series of N-(1-(1,1-dioxidotetrahydrothiophen-3-yl)-3-methyl-1H-pyrazol-5-yl)acetamide ethers as G protein-gated inwardly-rectifying potassium (GIRK) channel activators. From our previous lead optimization efforts, we have identified a new ether-based scaffold and paired this with a novel sulfone-based head group to identify a potent and selective GIRK1/2 activator. In addition, we evaluated the compounds in tier 1 DMPK assays and have identified compounds that display nanomolar potency as GIRK1/2 activators with improved metabolic stability over the prototypical urea-based compounds.

The G protein-gated inwardly-rectifying potassium channels (GIRK, Kir3) 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-5-yl-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 Kp > 0.6).
