Abstract

A large variety of antiherpes compounds was compared for their inhibitory activity against laboratory strains and clinical isolates of herpes simplex virus (HSV) type 1 and type 2. From studies performed in primary rabbit kidney cell cultures, six, E-5-(2-bromovinyl)-2'-deoxyuridine, E-5-(2-iodovinyl)-2'-deoxyuridine, 5-vinyl-2'-deoxyuridine, 2'-fluoro-5-iodoaracytosine, acycloguanosine, and 5-iodo-2'-deoxycytidine, emerged as the most potent and selective antiherpes agents. For HSV type 1, the 50% inhibitory doses (ID50) were 0.008, 0.012, 0.018, 0.017, 0.04, and 0.06 micrograms/ml, respectively; those for HSV type 2 were 1, 2, 0.1, 0.05, 0.04, and 0.3 microgram/ml, respectively. These compounds did not inhibit host-cell metabolism or replication of vaccinia virus except at concentrations 100--10,000 times greater than the ID50 for any HSV. All were significantly less inhibitory for a thymidine kinase (TK)-deficient mutant of HSV type 1 than for normal strains, suggesting that phosphorylation by virus-induced TK was required to produce specific inhibition of HSV replication.

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.
