1 The selectivity of S(+) flurbiprofen for inhibition of COX-1 was expressed as the ratio of IC50 for COX-2/COX-1. Flurbiprofen mitochondrially encoded cytochrome c oxidase II Homo sapiens
2 S(+) flurbiprofen inhibited PGE2 production of untreated tissue homogenates at an IC50 of 8 x 10(-10) M whereas, in the stimulated tissue, IC50 was found to be 3 x 10(-6) M. The selectivity of S(+) flurbiprofen for inhibition of constitutively present COX-1, relative to the inhibition of induced COX-2, was 3,600. Flurbiprofen mitochondrially encoded cytochrome c oxidase II Homo sapiens
