Lamivudine 13C,15N2, an impurity of Lamivudine (BCH-189), functions as an inhibitor of both HIV-1/2 reverse transcriptase and hepatitis B virus reverse transcriptase, classifying it as a nucleoside reverse transcriptase inhibitor (NRTIs).
Lamivudine (BCH-189) salicylate is an orally active nucleoside reverse transcriptase inhibitor (NRTI) that effectively inhibits the reverse transcriptase activity of both HIV 1 2 and hepatitis B virus. Moreover, it demonstrates the ability to penetrate the central nervous system [1] [2].
