Usage And Synthesis

Description

ML297 (1443246-62-5) is a selective GIRK 1/2 (Kir3.1/3.2) channel activator, IC50= 160, 887 and 914 nM for GIRK1/2, GIRK1/4 and GIRK1/3 respectively. Has no effect on GIRK2, GIRK2/3, Kir2.1 and Kv7.4 channels.1,2Displays antiseizure activity2and decreases anxiety-related behavior without sedative or addictive effects3. Reduces glucose- and IBMX-stimulated GLP-1 secretion with no effect on GIP in murine L and K cells.4Brain penetrant.

Uses

ML 297 is an anxiolytic drug which acts as a selective Kir3.1/3.2 (GIRK1/2) channel activator. It may be used in the treatment of epileptic seizures.

in vitro

in thallium flux assays, ml297 showed concentration-dependent efficacy when tested on cells expressing girk1/2. ml297 could also activate girk channels comprised of girk1/3 and girk1/4 subunit combinations. however, ml297 diaplayed a complete inability to modulate the activity of hek-293 cells expressing girk2 alone. a similar complete lack of efficacy was seen when ml297 was tested on hek-293 cells expressing girk2/3. therefore, it appeared that ml297 is only capable of activating girk channels containing a girk1 subunit [1].

in vivo

previous study performed an ascending dose study in mice and it was found that the animals appeared normal and not under obvious distress at all doses tested. ml297’s effects on locomotor activity as well as effects on motor function and coordination were further evaluated. results showed that ml297 at 60 mg/kg could immediate decrease in locomotor activity compared to the control group [1].

storage

Store at -20°C
