Caffeic Acid is an orally bioavailable, hydroxycinnamic acid derivative and polyphenol, with potential anti-oxidant, anti-inflammatory, and antineoplastic activities.

Abietic Acid (Sylvic acid) is a diterpene extracted from Pimenta racemosavar. grissea with antimicrobial, antiproliferative and anti-obesity activities. It inhibits lipoxygenase activity and may be studied in allergic diseases.

Diethylcarbamazine citrate (Caritrol) is an anthelmintic used primarily as the citrate in the treatment of filariasis, particular infestations with Wucheria bancrofti or Loa loa. It is an inhibitor of arachidonic acid metabolism in filarial microfilaria.

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].

Setileuton (MK0633) is a specific 5-LOX inhibitor and can be used in research on asthma and atherosclerosis.
