Lamivudine-¹⁵N,d₂  (Synonyms: BCH-189-¹⁵N,d₂)

Lamivudine-¹⁵N,d₂ is ¹⁵N and deuterated labeled Lamivudine (HY-B0250). Lamivudine (BCH-189) is an orally active nucleoside reverse transcriptase inhibitor (NRTI). Lamivudine can inhibit HIV reverse transcriptase 1/2 and also the reverse transcriptase of hepatitis B virus. Lamivudine salicylate can penetrate the CNS^[1][2].

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].
Lamivudine (1 μM) is potent inhibitor of hepatitis B virus (HBV) replication, shows antiviral activity in primary duck hepatocyte (PDH) cultures derived from ducklings congenitally infected with the duck hepatitis B virus (DHBV)^[2].
Lamivudine (0-20 μM; 2, 4, 9 d) inhibits DHBV replication with 50% inhibitory concentration of 0.55 μM^[2].
Lamivudine, combinded with penciclovir (9-[2-hydroxy-1-(hydroxymethyl)ethoxymethyl]guanine [PCV]), (1 μM; 2, 4, 9 d) shows synergistic effect, acts potent function in reducing the normally recalcitrant viral covalently closed circular (CCC) DNA form of DHBV^[2].

Lamivudine (20-500 mg/kg/d; p.o.; 15 or 45 d) causes oxidative stress and is toxic to rat liver^[3].
Lamivudine (50 mg/kg; i.p.; single dose) penetrates well in CNS and localizes in brain regions susceptible to HIV neurodegeneration in rat^[4].
