EC50: 0.16 μM (GIRK1/2), 18 μM (GIRK1/4)[1]

In Vitro ML 297 is completely inactive for GIRK2/3[1]. ML297 shows concentration-dependent efficacy in expressing GIRK1/2 cells and with an EC50 of 162 nM[2]. ML297 shows a complete inability to modulate the activity of HEK-293 cells expressing GIRK2 alone and GIRKGIRK2/3[2].
In Vivo ML297 (60 mg/kg; i.p.) shows a highly significant ability to both prevent convulsions and prevent fatality of the PTZ treatment[2]. Animal Model: 8-10 months old C57/BL6 male mice (approximately 30 g)[2] Dosage: 60 mg/kg Administration: Intraperitoneal injection Result: Most of the animals neither convulsions nor death.
