Imiloxan is an alpha(2) adrenoceptor antagonist and was developed for depression in the 1980's. In Phase 1 clinical trials imiloxan dosing led to hypersensitivity reactions; the molecule's development was discontinued. The present study revisits the in vitro metabolism of imiloxan using modern analytical methods. Human and rat liver microsomes convert imiloxan into a variety of metabolites many of which are unstable and or reactive. Imiloxan also yields high protein covalent binding in microsomal assays. Imiloxan is a useful test molecule for defining the relationship between liver covalent binding and idiosyncratic toxicity.
