Description

Application

ML133 hydrochloride may be used to study cell signaling that involves the function of potassium channels.

ML133 hydrochloride has been used as a Kir2.1 blocker to study the regulation of membrane excitability by inward-rectifier potassium channels (Kir2 family) in the dentate gyrus (DG) granule cells. It has also been used to study the effect of Kir2 on cortical neural activity.

Biochem/physiol Actions

Inhibitor of Kir2 family channels

ML133 hydrochloride is a selective inhibitor of the Kir2 family of inward rectifier (IRK, KCNJ) potassium channels. ML133 inhibits Kir2.1 with IC50 of 1.8 μM at pH 7.4 and 290 nM at pH8.5. It exhibits little selectivity against other members of Kir2.x family channels, but has no effect on Kir1.1 (IC50 > 300 μM), and displays weak activity for Kir4.1 (76 μM) and Kir7.1 (33 μM), making ML133 the most selective small molecule inhibitor of the Kir family reported to date. It also showed modest selectivity versus hERG and a larger panel of GPCRs, ion channels and transporters.
