| pubmed-article:2805177 | pubmed:abstractText | The new regioisomer derivatives 4a-f and 5a-f of 3-nitro-1,2,4-triazole (3-NTR) were synthesized for the development of new radiosensitizers of hypoxic cancer cells for radiotherapy. N(2)-Substituted 3-NTR derivatives 5a-f were stronger radiosensitizers of hypoxic cells in vitro (Chinese hamster V79 cells) than N(1)-substituted 3-NTR derivatives 4a-f, but in vivo they were weaker (SCCVII carcinoma cells inoculated into C3H/He mouse). | lld:pubmed |
