tcsc3355 ML365

ML365 is a novel selective small molecule inhibitor of TASK1(KCNK3) with IC50 of 4 nM(thallium influx fluorescent assay) and 16 nM(automated electrophysiology assay).

IC50 value: 4 nM/16 nM(thallium influx fluorescent assay/automated electrophysiology assay) [1]

Target: KCNK3 blocker

ML365 possesses more than 60-fold selectivity for inhibition of TASK1 over a closely-related, two-pore domain potassium channel, TASK3. ML365 displays little or no inhibition at 30 μM of more distantly related potassium channels, Kir2.1, potassium voltage-gated channel, KQT-like subfamily, member 2 (KCNQ2), and human ether-a go-go-related gene (hERG). Based on these criteria, ML365 is a best-in-class probe and is a useful pharmacological probe for in vitro studies of TASK1 function and in further studies aimed at developing therapeutic intervention.
