Abstract

The (-)-enantiomer of 2'-deoxy-3'-thiacytidine (3TC) was found to be a potent and selective inhibitor of human immunodeficiency virus types 1 (HIV-1) and 2 (HIV-2) in vitro. We determined its antiviral activity against a number of laboratory strains of HIV-1 and HIV-2 in a range of CD4-bearing lymphocyte cell lines (mean 50% inhibitory concentration [IC50] range, 4 nM to 0.67 microM). 3TC was also active against a range of HIV-1 strains in peripheral blood lymphocytes (mean IC50 range, 2.5 to 90 nM). The IC50 for cytotoxicity in seven lymphocyte cell cultures, including human peripheral blood lymphocytes, ranged from 0.5 to 6 mM. 3TC had no detectable antiviral activity against a range of other viruses or in cells chronically infected with HIV-1 or HIV-2. The effects of time of addition of the compound and varying the multiplicity of infection on the antiviral activity of 3TC were determined. The results showed that 3TC is a potent and selective inhibitor of HIV-1 and HIV-2 replication in vitro.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 3TC (Lamivudine) is a water-soluble nucleoside analog inhibitor of reverse transcriptase.

    “3TC (Lamivudine) is a water-soluble nucleoside analog inhibitor of reverse transcriptase38”

    From Pathogenic tau-induced piRNA depletion promotes neuronal death through transposable element dysregulation in neurodegenerative tauopathies (2018) · cites this paper as [38]

    The introduction identifies 3TC as a nucleoside analog, and the Discussion says its triphosphate form is assumed to inhibit viral reverse transcriptase; the paper presents its data as consistent with that mechanism. Our copy does not state that 3TC is water-soluble, and it does not directly establish reverse-transcriptase inhibition. (LLM, conf=0.86)

  • 3TC is FDA-approved for treatment of HIV/AIDS and Hepatitis B, both of which are caused by retroviruses.

    “that is FDA-approved for treatment of HIV/AIDS and Hepatitis B, both of which are caused by retroviruses”

    From Pathogenic tau-induced piRNA depletion promotes neuronal death through transposable element dysregulation in neurodegenerative tauopathies (2018) · cites this paper as [38]

    The Discussion reports that 3TC inhibits HIV-1 and HIV-2 replication in vitro and calls it a candidate for AIDS treatment, with clinical trials in progress. It does not support the claim that 3TC was FDA-approved or used to treat hepatitis B, nor does it classify hepatitis B as a retroviral disease. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
