Component

Time-dependent, slowly reversible inhibition of cyclooxygenase

Time-dependent, slowly reversible inhibition of cyclooxygenase. 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.

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 acts on it

  1. Conversion of the carboxylate moiety of flurbiprofen to an ester or amide abolishes slow tight-binding behaviour regardless of halogenation state, and contrary to prior predictions a halogen substituent is not sufficient to confer slow tight-binding behaviour.
