Background:

Bromoenol lactone-d₇(BEL-d₇) contains seven deuterium atoms at the 2, 3, 4, 5, 6, 7, and 8 positions. It is intended for use as an internal standard for the quantification of BEL by GC-or LC-mass spectrometry (MS). BEL is a selective, potent, irreversible, mechanism-based inhibitor of phospholipase A₂(iPLA₂) with a K_ivalue of 180 nM.¹It also inhibits macrophage iPLA₂in a concentration-dependent manner with an IC₅₀value of 60 nM and is an effective enzyme-activated irreversible inhibitor of chymotrypsin (K_i= 636 nM).^2,3
