(R)-Flurbiprofen is a COX-inactive enantiomer of the racemic non-selective COX inhibitor flurbiprofen (Item No. 70250) that has diverse biological activities. It inhibits γ-secretase activity in vitro and, in vivo, it reduces formation of amyloid-β peptide 1-42 (Aβ42) and improves axonal transport in young Aβ-plaque free mice but not old mice with existing Aβ plaques in the Tg2576 transgenic model of Alzheimer''s disease. (R)-Flurbiprofen inhibits NF-kB activation and DNA binding as well as AP-1 DNA binding in RAW 264.7 macrophages and reduces paw edema in a rat model of zymosan-induced inflammation via COX-independent inhibition of NF-κB and AP-1 activation when administered at doses of 1, 3, and 9 mg/kg. It also suppresses prostate tumor cell growth in vitro by inducing p75^NTR protein expression and reduces tumor growth and metastasis in multiple mouse models of intestinal neoplasia.

(R)-2-Flurbiprofen is the R-isomer of Flurbiprofen (F598700), an anti-inflammatory used as an analgesic.

ChEBI: (R)-flurbiprofen is a flurbiprofen. It is an enantiomer of a (S)-flurbiprofen.
