Ketorolac-¹³C₆  (Synonyms: RS37619-¹³C₆)

Ketorolac-¹³C₆ (RS37619-¹³C₆) is ¹³C labeled Ketorolac. Ketorolac (RS37619) is a non-steroidal anti-inflammatory drug (NSAID), acting as a nonselective COX inhibitor, with IC₅₀s of 20 nM for COX-1 and 120 nM for COX-2. Ketorolac tromethamine is used as 0.5% ophthalmic solution for the research of allergic conjunctivitis, cystoid macular edema, intraoperative miosis, and postoperative ocular inflammation and pain. Ketorolac tromethamine is also a DDX3 inhibitor that can be used for cancer research^[1][4].

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.
