Chemical structure definitions are available for many Cayman products. See Chemical Structure Database for details.

Methyl arachidonyl fluorophosphonate (MAFP) is a selective, active-site directed, irreversible inhibitor of cPLA₂ and iPLA₂.^1,2,3 It inhibits A23187-induced arachidonic acid release from human platelets with an IC₅₀ value of 0.6 µM.¹ The IC₅₀ value for inhibition of iPLA₂ from P388D1 cells is 0.5 µM.² MAFP is a potent inhibitor of fatty acid amide hydrolase, exhibiting an IC₅₀ value of 2.5 nM. MAFP also binds to the CB₁ receptor in rat brain membrane preparations. The IC₅₀ values for MAFP and arachidonyl ethanolamide in this assay are 20 and 40 nM, respectively.⁴
