Lamivudine, a nucleoside analog, is a potent reverse transcriptase inhibitor, with IC50 value of 0.316 µM against human immunodeficiency virus type 1 (HIV-1) [1].
Reverse transcriptase is a RNA-dependent DNA polymerase, playing a critical role in retroviral replication. Thus, reverse transcriptase has been made a target of antiretroviral chemotherapy [1].
Lamivudine was most potent against simian retrovirus types 1 and 2 (SRV-1, SRV-2), and HIV-1, with IC50 values of 10, 0.316 and 0.316 µM, respectively, but did not inhibit foamy viruses and amphotrophic murine leukaemia virus (MLV-A) [1].
In human coinfected with HIV-1 and hepatitis B virus (HBV), Lamivudine (150 mg, b.i.d., p.o.) displayed dual efficacy through both delayed HIV-1 disease progression and a favorable biochemical and HBV virologic response. Twelve months of Lamivudine therapy led to HBV DNA and hepatitis B e antigen (HBeAg) losses of ∼40% and ∼20%, respectively, and more alanine aminotransferase (ALT) normalization than that in the placebo group [2].

Peripheral blood mononuclear cells (PBMCs) |
|
Reaction Conditions |
10 d incubation |
|
Applications |
Lamivudine inhibited p24 antigen production by HIV-I in PBMCs, with ED50s ranging from 0.07 to 0.2 μM. There was no toxicity in uninfected PBMC with concentrations of lamivudine up to 10 μM over a 10-day culture period. |

|
Dosage form |
7 mg drug tablet containing lamivudine, abacavir and dolutegravir Re-suspended in 100 μl distilled water for daily gavage |
|
Applications |
Oral drug treatment led to full viral suppression and protection from CD4 T cell depletion. Cessation of therapy resulted in viral rebound and CD4 T cell loss. |
