Fluorescein di-bD-glucopyranoside is a fluorescent probe that binds to the glucosylceramide receptor. The in vitro assays showed that it inhibits amide hydrolase and fatty acid amide hydrolase activities. Fluorescein di-bD-glucopyranoside can also inhibit the enzyme activity of gamma-aminobutyric acid (GABA) transaminase and oxadiazole synthase. This compound is a selective inhibitor of CB2 receptor, which is expressed in primary cells and has been shown to be involved in inflammatory responses.
Fluorescein Di-(?-D-glucopyranoside) is an ultrasensitive fluorogenic substrate for measurement of ?-glucosidase activity in vivo or in vitro.
