Arachidonyl trifluoromethyl ketone (ATK) is an analog of arachidonic acid.[1] that inhibits some isoforms of the enzyme phospholipase A2.[2] Specifically it inhibits the 85 kDa cystolic PLA2 (cPLA2).[2]

It has been studied as a neuroprotective agent after spinal cord injury,[2][3] and in animal models of multiple sclerosis.[4]
