What is UMBELLIFERYL ARACHIDONATE?
The Uses of UMBELLIFERYL ARACHIDONATE
7-hydroxycoumarinyl Arachidonate is the arachidonic acid ester of 7-hydroxycoumarin (umbelliferone) and behaves as a substrate for cPLA2. Hydrolysis of 7-hydroxycoumarinyl arachidonate by phospholipase results in the release of the fluorescent compound 7-hydroxycoumarin which can be monitored spectrophotometrically (excitation at 335 nm, emission at 450 nm).
The Uses of UMBELLIFERYL ARACHIDONATE
7-HC-arachidonate is a PLA2 fluorogenic substrate for use in assays with phospholipid and Ca2+. It is for use with purified enzymes, as this substrate is nonspecific. 7-HC-arachidonate is ideal for drug discovery, HTS, and similar applications.
What are the applications of Application
7-HC-arachidonate is a PLA2 fluorogenic substrate
Biological Activity
7-hydroxycoumarinyl-arachidonate (7-hca), a fluorogenic substrate for monoacylglycerol lipase (magl), can be used with magl as a novel fluorescence-based assay to screen small molecule inhibitors of magl.magl protein catalyzed the hydrolysis of 7-hca to generate arachidonic acid and the highly fluorescent 7-hydroxyl coumarin (7-hc). 7-hydroxycoumarin (7-hc) can be monitored spectrophotometrically (excitation at 335 nm, emission at 450 nm). release of 7-hc was measured using a fluorometer. magl protein catalyzed the hydrolysis of 7-hca with an apparent km of 9.8 μm and vmax of 1.7 mmol/min/mg of protein. the assay is specific for magl as assay buffer alone or heat-denatured magl protein showed no significant activity against 7-hca [1]. 7-hydroxycoumarinyl arachidonate is the arachidonic acid ester of 7-hydroxycoumarin (umbelliferone) and can be used as a substrate for cpla2. hydrolysis of 7-hydroxycoumarinyl arachidonate by phospholipase resulted in the release of the fluorescent compound [2,3].
