Metabolism of anandamide by amidohydrolase
Metabolism of anandamide by amidohydrolase. Species, exposure and limitations are retained in each linked claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
The time-dependent reduction in potency of anandamide toward inhibition of cannabinoid agonist binding in rat cerebellar membranes was blocked by ibuprofen but not by acetylsalicylic acid, sulindac, acetaminophen or to any significant extent by ketoprofen and naproxen, a direct assay of anandamide amidase gave a half-maximal inhibitory concentration for ibuprofen of approximately 400 micromolar, and that potency was of the same order as required for inhibition of cyclooxygenase-2 in cell-free systems and as the peak plasma concentrations following a two times 200 milligram dose regimen, so following therapeutic doses the metabolism of anandamide may be affected.
