- Abstract
The potassium (K
+ ) ion channel KCNK13 is specifically expressed in human microglia with elevated expression observed in post-mortem human brain tissue from patients with Alzheimer's disease. Modulation of KCNK13 activity by a small-molecule inhibitor is proposed as a potential treatment for neurodegenerative diseases. Herein, we describe the evolution of a series of KCNK13 inhibitors derived from a high-throughput screening campaign, resulting in CVN293 , a potent, selective, and brain permeable clinical candidate molecule. CVN293 demonstrated a concentration-dependent inhibition of the NLRP3-inflammasome mediated production of IL-1β from LPS-primed murine microglia. Cross-species pharmacokinetic data of CVN293 are also disclosed. These findings support the advancement of CVN293 in clinical trials., Competing Interests: The authors declare no competing financial interest., (© 2024 American Chemical Society.)- Published
