Fenoprofen-¹³C₆ sodium hydrate  (Synonyms: LILLY-53858-13C6 sodium hydrate)

Fenoprofen-¹³C₆ (LILLY-53858-¹³C₆) sodium hydrate is the ¹³C labeled Fenoprofen (HY-B1456A).Fenoprofen (LILLY-53858) is a nonsteroidal anti-inflammatory agent (NSAID) and inhibits cyclooxygenase (COX). Fenoprofen is a melanocortin receptors (MCRs) positive allosteric modulator (PAM). Fenoprofen also increases ERK1/2 activation in HEK293T cells. Fenoprofen has anti-arthritic activities and can be used for the study of rheumatoid arthritis and osteoarthritis^[1][2][3].

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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].
