Responses of the L5178Y tk+/tk− mouse lymphoma cell forward mutation assay ii: 18 coded chemicals

Abstract

Eighteen chemicals were tested for their mutagenic potential in the L5178Y tk+/− mouse lymphoma cell forward mutation assay by the use of procedures based upon those described by Clive and Spector [Mutat Res 44:269–278, 1975] and Clive et al [Mutat Res 59:61–108, 1979]. Cultures were exposed to the chemicals for 4 hr, then cultured for 2 days before plating in soft agar with or without trifluorothymidine (TFT), 3 μg/ml. The chemicals were tested at least twice. Significant responses were obtained with benzofuran, benzyl chloride, bromodi‐chloromethane, butylated hydroxytoluene, chlorendic acid, o‐chlorobenzalmalo‐nitrile, 1,2,3,4‐diepoxybutane, dimethyl formamide, dimethyl hydrogen phosphite, furfural, glutaraldehyde, hydroquinone, 8‐hydroxyquinoline, and resorcinol. Apart from bromodichloromethane, butylated hydroxytoluene and dimethyl hydrogen phosphite, rat liver S9 mix was not a requirement for the activity of any of these compounds. Chemicals not identified as mutagens were water, tert‐butyl alcohol, pyridine, and witch hazel.

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.
