KIR6.2/SUR1 CHANNEL ACTIVATOR VU0071063 (C005B-229389)

General description

A xanthine derivative that serves as a fast acting, reversible, and selective activator of Kir6.2/SUR1 channels (EC₅₀ = 7 µM). Directly occupies the binding site located within SUR1. Shown to be a more potent activator of Kir6.2/SUR1 than diazoxide (EC₅₀ = 120 µM). However, it does not affect Kir6.1/SURA2A or Kir6.2/SURA2A channels and is inactive against Kir2.1 and Kir2.2 (IC₅₀ >100 µM) and exhibits very weak inhibitory activity against Kir3.1/3.2 (IC₅₀ = 65 µM) and Kir2.3 (IC₅₀ = 91 µM) channels. Inhibits glucose-stimulated Ca²⁺ influx into mouse pancreatic β-cells.
