7-Acetoxy-4-methylcoumarin

7-Acetoxy-4-methylcoumarin is a fluorogenic substrate for carboxylesterase yielding a blue fluorescent solution upon cleavage. The compound has been used in aprotic media, a cell membrane environmental mimic, to study superoxide and related oxyl-radical reactions of model biological membranes dispersed in aqueous media. Due to the ability for AchE to cleave and activate 7-Acetoxy-4-methylcoumarin, the fluorogenic substrate has been used to study the AchE inhibitor Tacrine·HCl. The compound has also been isolated from Trigonella foenum graceum.
