| Bioactivity | Fenspiride-d5 is the deuterium labeled Fenspiride. Fenspiride, an orally active non-steroidal antiinflammatory agent, is an antagonist of H1-histamine receptor. Fenspiride inhibites phosphodiesterase 3 (PDE3), phosphodiesterase 4 (PDE4) and phosphodiesterase 5 (PDE5) activities with -log IC50 values of 3.44, 4.16 and approximately 3.8, respectively. Fenspiride can be used for the research of respiratory diseases[1][2][3]. |
| Invitro | 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]. |
