IQM-266 is a Downstream Regulatory Element Antagonist Modulator (DREAM) ligand with a KD of 4.63 μM. IQM-266 inhibits the KV4.3/DREAM current in a concentration-, voltage-, and time-dependent-manner. IQM-266 also modulates A-type outward potassium currents (IA) from rat dorsal root ganglia (DRG) neurons. IQM-266 can be used for neurological disease research, such as Alzheimer’s disease and Huntington's disease (HD) [1].
