Fenbufen-d₉ 

Fenbufen-d₉ (CL-82204-d9) is the deuterium labeled Fenbufen. Fenbufen (CL-82204) is an orally active non-steroidal anti-inflammatory drug (NSAID), with antipyretic effects. Fenbufen has potent activity in a variety of animal model, including carageenin edema, UV erythema and adjuvant arthritis. Fenbufen has inhibitory activities against COX-1 and COX-2 with IC50s of 3.9 μM and 8.1 μM, respectively. Fenbufen is a caspases (caspase-1, 3, 4, 5, 9) inhibitor[1][2][3][4][5].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
