Tarenflurbil, Flurizan or '''R-flurbiprofen''', is a single enantiomer of the racemate NSAID flurbiprofen. For several years, research and trials for the drug were conducted by Myriad Genetics, to investigate its potential as a treatment for Alzheimer's disease; that investigation concluded in June 2008 when the company announced it would discontinue development of the compound.

==Mechanism of action== At proposed therapeutic concentrations, this molecule lacks anti-inflammatory activity, and does not inhibit either cyclooxygenase 1 (COX-1) or cyclooxygenase 2 (COX-2) enzymes. Only the S-enantiomers of arylpropionic acid NSAID can potently inhibit COX, whereas the R-enantiomers exert almost no COX activity. R-Flurbiprofen is inefficiently converted into S-flurbiprofen, with 1.5% of the R-enantiomer undergoing bioinversion to the S-form. Although this compound lacks activity against COX, studies have shown that this drug is a potent reducer of levels of beta amyloid, the main constituent of amyloid plaques in Alzheimer's disease, and therefore there was interest in this drug as a therapeutic agent.
