Biological Activity for ML 297

ML 297 is a selective K_ir3.1/3.2 (GIRK1/2) channel activator (IC₅₀ values are 160, 887 and 914 nM for GIRK1/2, GIRK1/4 and GIRK1/3 respectively). Exhibits no effect on GIRK2, GIRK2/3, K_ir2.1 and K_v7.4 channels, and has minimal effect on a panel of other ion channels, receptors and transporters. Prevents PTZ-induced epileptic seizures in mice. Brain penetrant.
