Ipratropium-d₇ bromide  (Synonyms: Sch 1000-d₇ (bromide))

Ipratropium-d₇ (bromide)eis the deuterium labeled Ipratropium bromide. Ipratropium bromide (Sch 1000) is a muscarinic receptor antagonist, with binding IC50 values of 2.9 nM, 2 nM, and 1.7 nM for M1, M2, and M3 receptors, respectively. Ipratropium bromide can be used in the research for COPD (chronic obstructive pulmonary disease) and asthma[1][2][3].

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
