Arachidonate 5-lipoxygenase inhibitor
Arachidonate 5-lipoxygenase inhibitors are compounds that slow or stop the action of the arachidonate 5-lipoxygenase enzyme, which is responsible for the production of inflammatory leukotrienes. The overproduction of leukotrienes is a major cause of inflammation in asthma, allergic rhinitis, and osteoarthritis.
Examples of 5-LOX inhibitors include the pharmaceutical drugs meclofenamate sodium, zileuton and myxochelins/pseudochelin.
Some chemicals found in trace amounts in food, as well as some dietary supplements, have been shown to inhibit 5-LOX; these include baicalein, caffeic acid, curcumin, hyperforin and St John's wort.
acetyl-keto-beta-boswellic acid , one of the bioactive boswellic acids found in Boswellia serrata has been found to inhibit 5-lipoxygenase strongly as an allosteric inhibitor. Boswellia administration has been shown to reduce brain edema in patients irradiated for brain tumor and it's believed to be due to 5-lipoxygenase inhibition.
