Bioactivity | 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]. |
Invitro | 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]. |
