(Rac)-Talinolol-d₅ 

(Rac)-Talinolol-d₅ is the racemate of Talinolol. Talinolol (Cordanum) is a long-acting, cardioselective β1-adrenergic receptor blocker. Talinolol exhibits cardioprotective and antihypertensive activities. Talinolol is also a well-known and frequently used probe substrate for P-glycoprotein (P-gp) activity[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.
