Possible Interaction: Arachidonic Acid and Zileuton

supplement:

Arachidonic Acid

Research Papers that Mention the Interaction

Zileuton is an inhibitor of the enzyme 5-lipoxygenase that catalyzes conversion of arachidonic acid to leukotrienes.
Chest  •  2005  |  View Paper
In conclusion, zileuton was an effective inhibitor of 5-LO activity resulting in marked suppression of urinary LTE4 levels and possible redirection of arachidonic acid into the COX-2 pathway in a subset of subjects.
Cancer Prevention Research  •  2013  |  View Paper
Pre-treatment of SZ95 sebocytes with Zileuton partially prevented short-term arachidonic acid-induced effects, such as induction of LTB(4), increase of neutral lipid content and stimulation of interlekin-6 release.

However, zileuton significantly decreased AA release in macrophages accompanied by inhibition of phospholipase A2 translocation to cellular membranes.

Zileuton and celecoxib prevented oral carcinogenesis at the post-initiation stage through their inhibitory effects on arachidonic acid metabolism.
Clinical Cancer Research  •  2005  |  View Paper
In experimental models of inflammation, zileuton significantly reduced arachidonic-acid induced mouse ear edema (ED50 = 31 mg/kg) and also attenuated inflammatory cell accumulation in the rat pleural Arthus reaction.
The Journal of pharmacology and experimental therapeutics  •  1991  |  View Paper
Zileuton is an inhibitor of the enzyme 5-lipoxygenase, which forms leukotrienes from arachidonic acid.
Respiration  •  2013  |  View Paper
Interestingly, zileuton was effective in inhibiting biosynthesis of multiple AA metabolites, including leukotriene B4 (LTB4), 5-, 12-, 15-hydroxyeicosatetraenoic acid and prostaglandin E2 (PGE2), while celecoxib only suppressed PGE2 biosynthesis significantly at a high dose.
Carcinogenesis  •  2006  |  View Paper
After oral dosing, CO inhibitors such as indomethacin (20-40 mg/kg) and ketoprofen (40-80 mg/kg), zileuton (5-LO inhibitor, 20-80 mg/kg) and MK886 (5-LO-activating-protein inhibitor, 640 mg/kg) potently suppressed arachidonic acid (AA, 0.25 mg)-induced ear edema in mice.
