3-Aminobenzamide does not alter DNA repair in human fibroblasts through modulation of deoxynucleoside triphosphate
Abstract:
3-Aminobenzamide does not deplete cellular purine deoxynucleoside triphosphate pools as do the structurally-related ribonucleotide reductase inhibitors, the hydroxy- and amino-substituted benzohydroxamic acids. Thus, the previously reported ability of 3-aminobenzamide to inhibit de novo synthesis of DNA purines does not appear to be due to a direct effect on pools via inhibition of ribonucleotide reductase. The enhancement rather than inhibition by 3-aminobenzamide of DNA repair in the present studies, however, leaves open the possibility that pool modulation may play a role in cell systems where repair inhibitory effects are seen.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
