7-Hydroxycoumarinyl arachidonate  (Synonyms: 7-HCA; Umbelliferyl Arachidonate; 7-HC-arachidonate)

7-Hydroxycoumarinyl arachidonate (7-HCA) is a fluorogenic substrate of cytosolic phospholipase A2 (PLA2). 7-Hydroxycoumarinyl arachidonate is also a fluorogenic substrate for monoacylglycerol lipase (MAGL). MAGL protein catalyzes the hydrolysis of 7-Hydroxycoumarinyl arachidonat to generate Arachidonic acid (AA) and the highly fluorescent 7-hydroxyl coumarin (7-HC; HY-N0573). Release of 7-HC can be measured using a fluorometer^[1][2][3].

MAGL catalyzes the hydrolysis of 7-Hydroxycoumarinyl arachidonate (7-HCA) into arachidonic acid (AA) and 7-HC. Release of 7-HC, which is fluorescent, is monitored over time with excitation (Ex) at 355 nm and emission (Em) at 460 nm^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
