Description

Biochem/physiol Actions

Astermizole is a potent hERG potassium channel blocker (IC₅₀ of 0.9 nM) and may used as a pharmacological chaperone to correct folding defects and restore protein function for some mutated forms of hERG channels. It has also been studied for treatment of malaria, hERG and hEAG channel function in cancer and as a second generation antihistamine H-1 antagonist.

Astermizole is a potent hERG potassium channel blocker (IC₅₀ of 0.9 nM).
