PF-4191834 is a noniron chelating and non-redox inhibitor of the 5-Lipoxygenase (5-LOX) with an IC50 of 229 nM. PF-4191834 shows ~300-fold selectivity for 5-LOX over 12-LOX and 15-LOX and displays no activity toward the cyclooxygenase enzymes. PF-4191834

Phenidone (1-phenyl-3-pyrazolidinone) is a dual inhibitor of cyclooxygenases and lipoxygenases that ameliorates rat paralysis in experimental autoimmune encephalomyelitis by suppressing its target enzymes[1]. The lipoxygenase inhibitor phenidone is a potent hypotensive agent in the spontaneously hypertensive rat[2].
