Erysolin is a naturally occurring aliphatic isothiocyanate found in certain Brassicaceae species. It features a methylsulfonyl functional group attached to a butyl chain terminated by an isothiocyanate moiety. This compound is studied for potential chemopreventive and anti-inflammatory activities similar to other isothiocyanates such as sulforaphane. It arises from the enzymatic hydrolysis of the corresponding glucosinolate by myrosinase upon plant tissue disruption. Erysolin exhibits lipophilic character due to its hydrocarbon chain and sulfur-containing groups, influencing its bioavailability and membrane permeability in biological systems.
