Benzocaine-(ethyl-d₅)  (Synonyms: 苯佐卡因 d₅)

Benzocaine-(ethyl-d₅) is the deuterium labeled Benzocaine. Benzocaine shares a common receptor with all othe rLAs in the voltage-gated Na+ channel, with an IC50 of 0.8 mM tested with a potential of +30 mV.

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.
